I am really new to XML and JDOM so I have a noob question, sorry for that. I have a XML file and I want to insert value into it. My XML file is like that;
<?xml version="1.0"?>
<message>
<header>
<messageType> </messageType>
<sendFrom> </sendFrom>
<HostName> </HostName>
<sendTo> </sendTo>
<receiverName> </receiverName>
<date> </date>
</header>
<body>
</body>
</message>
So what I want is for example is to add value between <sendTo> </sendTo> and also I want to add <A> data </A> between <body> </body>. Can you please tell me how to do that ?
Thanks a lot.

If you use dom,you can do it as follows;
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(inputFile);
Node messageType= doc.getElementsByTagName("messageType").item(0);//zero tells the order in the xml
messageType.setTextContent("SMS");
I'd recommend using XStream for XML handling.

My XML file is in the following format:
<top>
<name></name>
<title></title>
<time></time>
</top>
<top>
...
</top>
<top>
...
</top>
I write the following code to read the xml file:
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new File(QUERY_FILE)); //LINE (*)
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("top");
But the problem is I get error as at line (*):
The markup in the document following the root element must be
well-formed.
It seems that error is because I have multiple root elements in the xml file. One solution could be I add maybe <doc></doc> outside all <top> elements. But is there any other way that I can directly read in such XML file as element arrays?
You can try to isolate each<top> element and trying to parse them separately, but that's a more troublesome solution than just wrapping <doc></doc> around the xml content..
One thing I've done in the past is instead of putting the root tags in the file itself, I just read the text into a string, and wrap the <doc></doc> tags around the string before I load the XML.
You are add this line for well-formed :
<?xml version="1.0" encoding="UTF-8"?> <!-- this line-->
<top>
<name></name>
<title></title>
<time></time>
</top>

I am trying to create an org.w3c.dom.Document object from an xml string. I have followed what many have suggested in other questions but the document ends up empty. What is wrong with the following code?
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(new InputSource(new StringReader(response.getResponseText())));
And the xml text in the string looks like the following (this comes from response.getResponseText())

Can anyone see what is wrong with my code? I ultimately just want to run a couple of xpath queries on the document...
I would suggest to start with setting docFactory.setNamespaceAware(true);, otherwise the parsing, the DOM built and the XPath implementation will not be able to work with XML with namespaces as you have posted.
I want to copy an node to a different Documentg, but it always has DOMException about
org.apache.harmony.xml.dom.NodeImpl.setNameNS(NodeImpl.java:227)
here is my code
private String getString(Node seqNode) {
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = factory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element root = doc.createElement("Test");
doc.appendChild(root);
/* following line will cause DOMException */
doc.importNode(seqNode, true);
...
...
} catch (Exception e) {
}
}
where seqNode belongs to other Document
does any body has idea about this issue? :-)
I ran into this problem too. I was getting this exception when calling either importNode() or cloneNode(). And BTW, the XML I was parsing/generating was not using namespaces.
It seems that the DOM parser (from Apache Harmony) that is included in Android is buggy. See this link: Issue 2735: Harmony DOM implementation is buggy and noncompliant. Everything works fine if the same code is executed using plain Java 1.6 (which isn't based on Harmony of course).
I tried setting setNamespaceAware(true) on the DocumentBuilder, but this did not help.
Eventually, I gave up and worked around the issue by using adoptNode() rather than importNode(). This is kind of incestuous, because it is stealing a node from one Document tree and putting it into another. But in my case, the first Document tree was only temporary, so I could do things this way.
I'm guessing, but it seems that you are trying to import node with namespace defined, where your target document does not have this namespace declared.
So, what namespaces are declared in source document? Did you declare any namespaces in target document?

and the original Document is generated by:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document dom = builder.parse(new ByteArrayInputStream(smil.getBytes()));
and the seqNode represents the "seq" node (the child of body tag)
I want to copy "seq" and all of it's childs to new Document
I want to create XML in Java.
DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder;
docBuilder = dbfac.newDocumentBuilder();
Document doc = docBuilder.newDocument();
but Java automatically creates declaration like this
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
How can I remove encoding="UTF-8" standalone="no" so it will be
<?xml version="1.0"?>
Thanks!
Why do you need to remove an encoding? But..
doc.setXmlStandalone(true);
will erase standalone="no"
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
This would resolve your issue, verified at JDK 6
I think there is no legal way to exclude theese attributes from generation.
But after it's generated you can use XSLT to remove this.
I think this is a good way.
Im in the process of creating XML as a Node for a RMI program I am developing but I have run across a problem. I can create the XML using DOM but I am struggling to add namespace and version to the top of my XML. I have tried using setAttribute and setAttributeNS but at the moment lost in what else I can do.
The java code to create the element is:
DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = dbfac.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Node root = doc.createElement("Request");
doc.appendChild(root);
//code ommited
The result I get currently is:
<Request>
<Identification>
<UserID>user</UserID>
<Password>pass</Password>
</Identification>
</Request>
In the request section I need it to look like:
<Request xsi:noNamespaceSchemaLocation="URL" Version="1.0">
Any help will be appreciated to help solve this issue!
Thanks
I think you'd want something like:
...
Element root = doc.createElement("Request");
root.setAttributeNS("http://www.w3.org/2001/XMLSchema-instance", "xsi:noNamespaceSchemaLocation", "URL");
root.setAttribute("Version", "1.0");
doc.appendChild(root);
...
Defining root as an Element gives you the .setAttribute* methods.
This would give you
<Request Version="1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="URL"/>
I know that includes a bit more, but the xmlns:xsi attribute is needed so that the xsi namespace is defined.
