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())
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">

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 am receiving following XML response via Jersey client
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><aaa><bbb key="Data"><?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<my-data xsi:noNamespaceSchemaLocation="MyData.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<data name="abc" uniqueId="4fe95637-a381-4e0c-bf7f-49f794df5f23">
<variable var1="xyz" value="44"/>
</data>
</my-data>
</bbb></aaa>
I am saving this as an XML file and getting 'premature end of file' error during parsing, since the XML is malformed (duplicate XML declarations)...is there a way to remove following duplicate entry from the output?
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
Following is my Java code snippet:
String output = response.getEntity(String.class);
file = writeResponseToFile(output,"MyData.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(file); //Error
Ideally, you should fix the problem at the source. What you're receiving is not XML because having more than one XML declaration violates XML's basic grammar, making the data not well-formed.
If it is impossible to properly fix the problem at the source, and you wish to attempt repair, you have to treat that data as text, not XML, until you remove the extra XML declaration (via text-level operations, not XML parsing).
Fix the xml that you are receiving. You receive two declarations in the xml.
The xml is malformed. Remember in Jersey, you can receive files on JSON, xml, html, etc, via annotations, with #Produces.
And remember that you have xml validators on internet, to valid your xml.

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 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.

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.
