node.getNodeType is not working as expected in case of ELEMENT_NODE

I am trying to fetch all the elemnt type node only , and then i have some specific operation to do , but the node.getNodeType is not working as expected in case of ELEMENT_NODE - it is going in if block for all child node
Sample xml -
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:pain.002.001.05">
<CstmrPmtStsRpt>
<GrpHdr>
<MsgId>00990119071512383635</MsgId>
<CreDtTm>2019-07-15T12:38:36.304+05:30</CreDtTm>
<InitgPty>
<Nm>appSend</Nm>
</InitgPty>
</GrpHdr>
....
here is my code - what I want to do is for elements like MsgId i want to do something and for GrpHdr i want do some different operation
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setIgnoringComments(true);
dbf.setValidating(true);
dbf.setNamespaceAware(true);
dbf.setIgnoringElementContentWhitespace(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new File(fileName));
doc.getDocumentElement().normalize();
NodeList nodeList = doc.getElementsByTagName("*");
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
node.normalize();
if( node.getNodeType() == Node.ELEMENT_NODE ){
// do operation for only elements
}else{
// do other operation for non elements
}
}
}catch (Exception e){
}
Does anybody have faced similar issue ,
Thank you in advance

well , the following isn't a good workaround - but this is how i fixed it
Elements - will have just one child always.
So i tweaked it with below code -
if( node.getChildNodes().getLength() != 1 ){
// do operation for only non - elements
}else{
// do other operation for elements
}
I would say this is just a work around, not a good solution

how to parse xml to java in nodelist

that is my xml
<?xml version = "1.0" encoding = "UTF-8"?>
<ns0:GetADSLProfileResponse xmlns:ns0 = "http://">
<ns0:Result>
<ns0:eCode>0</ns0:eCode>
<ns0:eDesc>Success</ns0:eDesc>
</ns0:Result>
</ns0:GetADSLProfileResponse>
that is my code in java I need to know how to start in this
I tried some code online but still did not solve my problem
how to get the values in the result to loop in it and get 0 in ecode and Success in eDesc
CustomerProfileResult pojo = new CustomerProfileResult();
String body = readfile();
System.out.println(body);
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document dom = db.parse(new InputSource(new StringReader(body)));
XPath xpath =XPathFactory.newInstance().newXPath();
XPathExpression name = xpath.compile("/xml/GetADSLProfileResponse/Result");
NodeList nodeName = (NodeList) name.evaluate(dom, XPathConstants.NODESET);
if(nodeName!=null){
}

Summary
You can try to following expression which allows you to select nodes without caring the namespace ns0:
/*[local-name()='GetADSLProfileResponse']/*[local-name()='Result']/*
Explanation
In your syntax, several parts were incorrect. Let's take a look together. XPath syntax /xml means that the root node of the document is <xml>, but the root element is <ns0:GetADSLProfileResponse>; GetADSLProfileResponse is incorrect too, because your XML file contains a namespace. Same for Result:
/xml/GetADSLProfileResponse/Result
In my solution, I ignored the namespace, because your namespace provided is incomplet. Here's a full program to get started:
String XML =
"<?xml version = \"1.0\" encoding = \"UTF-8\"?>\n"
+ "<ns0:GetADSLProfileResponse xmlns:ns0 = \"http://\">\n"
+ " <ns0:Result>\n"
+ " <ns0:eCode>0</ns0:eCode>\n"
+ " <ns0:eDesc>Success</ns0:eDesc>\n"
+ " </ns0:Result>\n"
+ "</ns0:GetADSLProfileResponse> ";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document;
try (InputStream in = new ByteArrayInputStream(XML.getBytes(StandardCharsets.UTF_8))) {
document = builder.parse(in);
}
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xPath.compile("/*[local-name()='GetADSLProfileResponse']/*[local-name()='Result']/*");
NodeList nodeList = (NodeList) expr.evaluate(document, XPathConstants.NODESET);
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
System.out.println(node.getNodeName() + ": " + node.getTextContent());
}
It prints:
ns0:eCode: 0
ns0:eDesc: Success

navigating hierarchy of xml input file

How do I list the element names at a given level in an xml schema hierarchy? The code I have below is listing all element names at every level of the hierarchy, with no concept of nesting.
Here is my xml file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><?xml-stylesheet type="text/xsl" href="CDA.xsl"?>
<SomeDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:something">
<title>some title</title>
<languageCode code="en-US"/>
<versionNumber value="1"/>
<recordTarget>
<someRole>
<id extension="998991"/>
<addr use="HP">
<streetAddressLine>1357 Amber Drive</streetAddressLine>
<city>Beaverton</city>
<state>OR</state>
<postalCode>97867</postalCode>
<country>US</country>
</addr>
<telecom value="tel:(816)276-6909" use="HP"/>
</someRole>
</recordTarget>
</SomeDocument>
Here is my java method for importing and iterating the xml file:
public static void parseFile() {
//get the factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
//Using factory get an instance of document builder
DocumentBuilder db = dbf.newDocumentBuilder();
//parse using builder to get DOM representation of the XML file
Document dom = db.parse("D:\\mypath\\somefile.xml");
//get the root element
Element docEle = dom.getDocumentElement();
//get a nodelist of elements
NodeList nl = docEle.getElementsByTagName("*");
if (nl != null && nl.getLength() > 0) {
for (int i = 0; i < nl.getLength(); i++) {
Node node = nl.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
System.out.println("node.getNodeName() is: "+node.getNodeName());
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
The output of the above program is:
title
languageCode
versionNumber
recordTarget
someRole
id
addr
streetAddressLine
city
state
postalCode
country
telecom
Instead, I would like to output the following:
title
languageCode
versionNumber
recordTarget
It would be nice to then be able to list the children of recordTarget as someRole, and then to list the children of someRole as id, addr, and telecom. And so on, but at my discretion in the code. How can I change my code to get the output that I want?

You're getting all nodes with this line:
NodeList nl = docEle.getElementsByTagName("*");
Change it to
NodeList nl = docEle.getChildNodes();
to get all of its children. Your print statement will then give you the output you're looking for.
Then, when you iterate through your NodeList, you can choose to call the same method on each Node you create:
NodeList children = node.getChildNodes();
If you want to print an XML-like structure, perhaps a recursive method that prints all child nodes is what you are looking for.

You could re-write the parseFile (I'd rather call it parseChildrenElementNames) method to take an input String that specifies the element name for which you want to print out its children element names:
public static void parseChildrenElementNames(String parentElementName) {
// get the factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
// Using factory get an instance of document builder
DocumentBuilder db = dbf.newDocumentBuilder();
// parse using builder to get DOM representation of the XML file
Document dom = db
.parse("D:\\mypath\\somefile.xml");
// get the root element
NodeList elementsByTagName = dom.getElementsByTagName(parentElementName);
if(elementsByTagName != null) {
Node parentElement = elementsByTagName.item(0);
// get a nodelist of elements
NodeList nl = parentElement.getChildNodes();
if (nl != null) {
for (int i = 0; i < nl.getLength(); i++) {
Node node = nl.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
System.out.println("node.getNodeName() is: "
+ node.getNodeName());
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
However, this will only consider the first element that matches the specified name.
For example, to get the list of elements under the first node named someRole, you would call parseChildrenElementNames("someRole"); which would print out:
node.getNodeName() is: id
node.getNodeName() is: addr
node.getNodeName() is: telecom

Android - Reading XML issues

I've got an app that consumes a .NET web service which returns an XML string of data. I'm trying to read this XML and insert it into the local SQLite DB but I'm having some trouble. Here's a sample of the xml:
<?xml version="1.0" encoding="utf-8" ?>
<string xmlns="RemoteWebService"><OpenIssues> <Table> <IssueID>15351</IssueID> <IssueSummary>Computer keeps crashing. This continues to be a problem</IssueSummary> <LocationName>West Side</LocationName> <Status>WIP</Status> <CustomerID>89755</CustomerID> <CustomerName>West Side Computers</CustomerName> <CustomerShortName>WSC</CustomerShortName> <Notes /> <STATUS1>Work In Progress</STATUS1> <SubmittedBy>WSC - Tom Johns</SubmittedBy> <EQ_Replaced>true</EQ_Replaced></Table> </OpenIssues></string>
Using DOM, I'm trying to parse the results like so:
private void GetLatestData(String response) throws ParserConfigurationException, SAXException, IOException{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(response)));
//Normalize the document.
doc.getDocumentElement().normalize();
//Get Root Node.
NodeList nodeList = doc.getElementsByTagName("Table");
Node node = nodeList.item(0);
//Get Child Nodes.
for(int i = 0; i < node.getChildNodes().getLength(); i++){
IssueInfo issue = new IssueInfo();
Node tempNode = node.getChildNodes().item(i);
if(tempNode.getNodeName().equalsIgnoreCase("IssueID")){
issue.setIssueNumber(Long.parseLong(tempNode.getTextContent()));
}
if(tempNode.getNodeName().equalsIgnoreCase("IssueSummary")){
issue.setIssueNumber(Long.parseLong(tempNode.getTextContent()));
}
if(issue.getIssueNumber() > 0 && issue.getIssueSummary() != null){
creator = new IssueInfoCreator(this, DBVersion);
creator.open();
creator.InsertIssue(issue.getIssueNumber(), DateFormat.getDateInstance().format(new Date()), issue.getIssueSummary());
creator.close();
}
}
}
When I run it through the debugger, it gets "IssueID" just fine but how can I get it to pickup the next node "IssueSummary" right after that so I can insert the data at once? It seems like I need another loop somewhere, just not too sure where though.

If I understand your question correctly, this is what you may need to do.
Node node = nodeList.item(0);
Returns
<Table>
<IssueID>15351</IssueID>
<IssueSummary>Computer keeps crashing. This continues to be a problem</IssueSummary>
<Notes />
</Table>
node.getChildNodes().getLength();
Returns 3.
IssueInfo issue = new IssueInfo();
// Go through each child and find out node name and populate it.
for(int i = 0; i < node.getChildNodes().getLength(); i++){
Node tempNode = node.getChildNodes().item(i);
if(tempNode.getNodeName().equalsIgnoreCase("IssueID")){
issue.setIssueNumber(Long.parseLong(tempNode.getTextContent()));
}
if(tempNode.getNodeName().equalsIgnoreCase("IssueSummary")){
issue.setIssueNumber(Long.parseLong(tempNode.getTextContent()));
}
}
Move if logic out of the loop.
if(issue.getIssueNumber() > 0 && issue.getIssueSummary() != null){
creator = new IssueInfoCreator(this, DBVersion);
creator.open();
creator.InsertIssue(issue.getIssueNumber(), DateFormat.getDateInstance().format(new Date()), issue.getIssueSummary());
creator.close();
}

Seems like a simple DOM traversing issue.
If you can guarantee the next node is the summary, you could try using the getNextSibling() method for nodes
I modified your code so I could call it without using your classes. This is the code I used:
private static void GetLatestData(String response) {
try{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
/* the following 2 lines help you eliminate whitespace
from your xml DOM tree */
dbf.setValidating(true);
dbf.setIgnoringElementContentWhitespace(true);
DocumentBuilder db = dbf.newDocumentBuilder();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(response)));
//Normalize the document.
doc.getDocumentElement().normalize();
//Get Root Node.
NodeList nodeList = doc.getElementsByTagName("Table");
Node node = nodeList.item(0);
long issueNumber;
String summary;
//Get Child Nodes.
for(int i = 0; i < node.getChildNodes().getLength(); i++){
Node tempNode = node.getChildNodes().item(i);
if(tempNode.getNodeName().equalsIgnoreCase("IssueID")){
issueNumber = (Long.parseLong(tempNode.getTextContent()));
Node summaryNode = tempNode.getNextSibling();
summary = summaryNode.getTextContent();
System.out.println(String.format("Issue # %d, Summary: %s" , issueNumber,summary));
}
}
}catch(Exception exception){
exception.printStackTrace();
}
}
and I call it like this:
GetLatestData("<OpenIssues> " +
"<Table> " +
"<IssueID>15351</IssueID>" +
"<IssueSummary>Computer keeps crashing. This continues to be a problem</IssueSummary> " +
"<Notes />" +
"</Table></OpenIssues> ");
from a simple Java class. It's working all right for me, at least. It prints out:
Issue # 15351, Summary: Computer keeps crashing. This continues to be a problem

*smacks forehead*
issue will never have more than one value set, as it's created anew for each child node.
Just swap the two lines to create issue only once:
IssueInfo issue = new IssueInfo();
for(int i = 0; i < node.getChildNodes().getLength(); i++){
...
You should probably move the final if outside the for too, so it's not executed more than once.
AND you'll need to actually set the summary in the second if not. You're setting the 'issue number' twice.

Finally found the resolution to this with the help of my coworker and some digging around. It should be noted that we changed the WebService that returned a string from DataSet.GetXml() to an XmlDocument.InnerXml. This removed the spaces in between the nodes and then we were able to move forward from there. Here's the final code we used:
public void GetLatestData(SoapPrimitive xml)throws ParserConfigurationException, SAXException, IOException{
//get the factory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
//Using factory get an instance of document builder
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc;
//parse using builder to get DOM representation of the XML file
InputSource is = new InputSource(new StringReader(xml.toString()));
doc = db.parse(is);
//Clear out Issues table first.
creator = new IssueInfoCreator(this, DBVersion);
creator.open();
creator.ClearIssueTable();
creator.close();
NodeList nodes = doc.getElementsByTagName("Table");
for(int i = 0; i < nodes.getLength(); i++) {
IssueInfo issue = new IssueInfo();
Element e = (Element)nodes.item(i);
issue.setIssueNumber(Long.parseLong(XMLfunctions.getValue(e, "IssueID")));
issue.setIssueSummary(XMLfunctions.getValue(e, "IssueSummary"));
issue.setDateReceived(DateFormat.format("MM/dd/yyyy hh:mm:ss", System.currentTimeMillis()).toString());
if(issue.getIssueNumber() > 0 && issue.getIssueSummary() != null){
creator = new IssueInfoCreator(this, DBVersion);
creator.open();
creator.InsertIssue(issue.getIssueNumber(), issue.getDateReceived(), issue.getIssueSummary());
creator.close();
}
}
}
And here is the getValue method of the XMLfuntions class:
public static String getValue(Element item, String str) {
NodeList n = item.getElementsByTagName(str);
return XMLfunctions.getElementValue(n.item(0));
}
public final static String getElementValue( Node elem ) {
Node kid;
if( elem != null){
if (elem.hasChildNodes()){
for( kid = elem.getFirstChild(); kid != null; kid = kid.getNextSibling() ){
if( kid.getNodeType() == Node.TEXT_NODE ){
return kid.getNodeValue();
}
}
}
}
return "";
}
Definately not taking credit for this, I found it here:
Programmer XR and modified it to my needs.
Hopefully this will help other people out!

java xml dom parsing

I have this project I'm working on where I want to parse an xml file that looks like this:
<?xml version='1.0' encoding='UTF-8'?>
<projectlist>
<project>
<name>SuperDuperApp</name>
<type>batch</type>
<prod>
<server>testserver01</server>
</prod>
<qa>
<server>testserver01</server>

With this method parsing the file and trying to print out in the format:
name: SuperDuperApp
type: batch

server: testserver12
server: testserver13
server: testserver14
etc.
public void parseXML() {

} catch (Exception e) {
e.printStackTrace();

lstProject.validate();
}
So I rewrote my method and now I'm just stuck <---newb

Check the documentation for Node. Each node has a method getChildNodes. Check that for the existence of children nodes and than iterate over them like you are doing.

If your xml was created using an xsd schema, you could instead use JAXB to create classes for it, using the xjc tool. That should make your life a bit easier.

I think it's appropriate to use XSLT transform in your case (much less boilerplate code) Look at TransformerFactory and java api for xml processing.

As a q&d solution you could apply the same strategy as for getting "project" node:
...
System.out.println("servers:");
NodeList sList = eElement.getElementsByTagName("server");
for (int i = 0; i < sList.getLength(); i++) {
String stuff = sList.item(i).getFirstChild().getNodeValue();
System.out.println(stuff);
}
