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

Node (Java Platform SE 8)

Get node text with HTML task inside

I try to examine with Java XPath an html string like this:
<app>
<elem class="A">value1</elem>
<elem class="B">value2a<br />value2b</elem>
<elem class="C">value3</elem>
</app>
Actually for obtain the elem's value i use this code
public String getValue(String xml, String classValue){
XPath xpath = XPathFactory.newInstance().newXPath();
InputSource source = new InputSource(new StringReader(xml));
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
document = db.parse(source);
String xpathRequest = "//*[#class='"+classValue+"']/text()";
String value = xpath.evaluate(xpathRequest , document);
return value;
}
For classes A and C works fine, but when i ask the content of task with class B obtain only value2a
How i can get the complete string of node?

Simply run
String xpathRequest = "//*[#class='"+class+"']";
String value = this.xpath.evaluate(xpathRequest , document);
This will select the <elem> node and when converted to a String build the concatenation of all text content, e.g. Value2a Value2b
To get a list of all text contents below a Elem you need to select them as NodeSet:
String xpathRequest = "//*[#class='"+class+"']/text()";
NodeList textNodes = (NodeList)xpath.evaluate(xpathRequest , document, XPathConstants.NODESET);
ArrayList<String> texts = new ArrayList<>();
for (int i=0; i<textNodes.getLength(); i++)
texts.add(textNodes.item(i).getTextContent());

It is because xpath will return 2 value at this moment. Try below :-
List<WebElement> allprice = driver.findElements(By.xpath("//*[#class='B']/text()"));
for(WebElement a:WebElement allprice){
System.out.println(a.gettext());
}

Getting html string from xml document

I have the following xml:
<version>
<name>2.0.2</name>
<description>
-Stop hsql database after close fist <br />
-Check for null category name before adding it to the categories list <br />
-Fix NPE bug if there is no updates <br />
-add default value for variable, change read bytes filter, and description of propertyFile <br />
-Change HTTP web Proxy (the “qcProxy” field ) to http://web-proxy.isr.hp.com:8080 <br />
</description>
<fromversion>>=2.0</fromversion>
</version>
I want to return description tag string content using Java?

This is pretty standard Java XML parsing, you can find it anywhere on the internet, but it goes like this using XPath in standard JDK.
String xml = "your XML";
// load the XML as String into a DOM Document object
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = docBuilder.parse(bis);
// XPath to retrieve the content of the <version>/<description> tag
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("/version/description");
Node description = (Node)expr.evaluate(doc, XPathConstants.NODE);
System.out.println("description: " + description.getTextContent());
Edit
Since you are having XML <br/> in your text content, it cannot be retrieved from Node.getTextContent(). One solution is to transform that Node to XML String equivalent, stripping the root node <description>.
This is a complete example:
String xml = "<version>\r\n" + //
" <name>2.0.2</name>\r\n" + //
" <description>\r\n" + //
"-Stop hsql database after close fist <br />\r\n" + //
"-Check for null category name before adding it to the categories list <br />\r\n" + //
"-Fix NPE bug if there is no updates <br />\r\n" + //
"-add default value for variable, change read bytes filter, and description of propertyFile <br />\r\n" + //
"-Change HTTP web Proxy (the “qcProxy” field ) to http://web-proxy.isr.hp.com:8080 <br />\r\n" + //
"</description>\r\n" + //
" <fromversion>>=2.0</fromversion>\r\n" + //
"</version>";
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = docBuilder.parse(bis);
// XPath to retrieve the <version>/<description> tag
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("/version/description");
Node descriptionNode = (Node) expr.evaluate(doc, XPathConstants.NODE);
// Transformer to convert the XML Node to String equivalent
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter sw = new StringWriter();
transformer.transform(new DOMSource(descriptionNode), new StreamResult(sw));
String description = sw.getBuffer().toString().replaceAll("</?description>", "");
System.out.println(description);
prints:
-Stop hsql database after close fist <br/>
-Check for null category name before adding it to the categories list <br/>
-Fix NPE bug if there is no updates <br/>
-add default value for variable, change read bytes filter, and description of propertyFile <br/>
-Change HTTP web Proxy (the “qcProxy” field ) to http://web-proxy.isr.hp.com:8080 <br/>
Edit 2
In order to have them all you need to get a NODESET of the different nodes and iterate over it to do the exact same operation as above.
// XPath to retrieve the content of the <version>/<description> tag
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("//description");
NodeList descriptionNode = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
List<String> descriptions = new ArrayList<String>(); // hold all the descriptions as String
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
for (int i = 0; i < descriptionNode.getLength(); ++i) {
Node descr = descriptionNode.item(i);
StringWriter sw = new StringWriter();
transformer.transform(new DOMSource(descr), new StreamResult(sw));
String description = sw.getBuffer().toString().replaceAll("</?description>", "");
descriptions.add(description);
}
// here you can do what you want with the List of Strings `description`

Parsing xml name-value fields

In my xml, I am seraching for speciffic names and want to retrieve their value.
for example i have this field:
<n0:field>
<n0:name n4:type="n3:string" xmlns:n3="http://www.w3.org/2001/XMLSchema" xmlns:n4="http://www.w3.org/2001/XMLSchema-instance">LifePolicyID</n0:name>
<n0:value n6:type="n5:string" xmlns:n5="http://www.w3.org/2001/XMLSchema" xmlns:n6="http://www.w3.org/2001/XMLSchema-instance">1</n0:value>
</n0:field>
I try to get the value of the LifePolicyID name.
Is there a way to do it programatticly?
Right now i am usin Xpath like this:
XPathExpression xpe = xpath.compile("//*[name/text()='" + name +"']/value");
Where name is in this case is LifePolicyID. But it dont work.
Any ideas?

Your code seems to work for me
String xml =
"<n0:field xmlns:n0='http://test/uri'>" +
" <n0:name n4:type='n3:string' xmlns:n3='http://www.w3.org/2001/XMLSchema' xmlns:n4='http://www.w3.org/2001/XMLSchema-instance'>LifePolicyID</n0:name>" +
" <n0:value n6:type='n5:string' xmlns:n5='http://www.w3.org/2001/XMLSchema' xmlns:n6='http://www.w3.org/2001/XMLSchema-instance'>1</n0:value>" +
"</n0:field>";
String name = "LifePolicyID";
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression xpe = xpath.compile("//*[name/text()='" + name +"']/value");
Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(xml)));
System.out.println(xpe.evaluate(doc));

Parse XML with XPath & namespaces in Java

Can you help me adjust this code so it manages to parse the XML? If I drop the XML namespace it works:
String webXmlContent = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<foo xmlns=\"http://foo.bar/boo\"><bar>baz</bar></foo>";
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder builder = domFactory.newDocumentBuilder();
org.w3c.dom.Document doc = builder.parse(new StringInputStream(webXmlContent));
NamespaceContextImpl namespaceContext = new NamespaceContextImpl();
namespaceContext.startPrefixMapping("foo", "http://www.w3.org/2001/XMLSchema-instance");
XPath xpath = XPathFactory.newInstance().newXPath();
xpath.setNamespaceContext(namespaceContext);
XPathExpression expr = xpath.compile("/foo/bar");
Object result = expr.evaluate(doc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
System.out.println("Got " + nodes.getLength() + " nodes");

You must use a prefix in your XPath, e. g.: "/my:foo/my:bar" You can choose any prefix you like - it doesn't have anything to do with the prefixes you use or don't use in the XML file - but you must choose one. This is a limitation of XPath 1.0.
You must perform prefix mapping from "my" to "http://foo.bar/boo" (not to "http://www.w3.org/2001/XMLSchema-instance")
