XML DocumentBuilder.parse()

It seems that every example given is reading XML from a file. But if what I have is a String, and I do not want to write it to a file, how should I use this function?
Thanks.

Use a java.io.StringReader in the constructor of a org.xml.sax.InputSource object. This object can be used in methods such as org.apache.xerces.parsers.SAXParser.parse(InputSource)

URGENT: javax.xml.parsers.DocumentBuilder.parse() method issue

Hi folks,
I have an urgent parsing problem. I developed an app with JDK1.4 and now it needs to run on JDK1.3.1. The problem is this:
If I use the DocumentBuilder.parse() method shipped with JDK1.4 it will parse a document containing namespaces WITHOUT a namespace declaration in the root element. However, since XML support doesn't ship with JDK1.3.1 I need to use JAXP. If I try this with the DocumentBuilder.parse() version shipped with JAXP (latest version) the parse method throws a NullPointerException. If I put the namespace declaration in the document it will parse fine. I tried setting the DocumentBuilderFactory.setNamespaceAware() explicitly to false (should be the default) but no luck. Any ideas other than adding the declaration (long story why I don't want it there...)
thanks

example, with declaration of namespace:
<?xml version="1.0" encoding="UTF-8"?>
<pre:root xmlns:inn="http://blablabla/inn/version/1.0/">
<pre:metadata>
<pre:dublin-core>
<pre:title>mytitle</pre:title>
<pre:description>mydesc</pre:description>
<pre:creator>bjmann</pre:creator>
</inn:dublin-core>
</pre:root>
example, without declaration:
<?xml version="1.0" encoding="UTF-8"?>
<pre:root>
<pre:metadata>
<pre:dublin-core>
<pre:title>mytitle</pre:title>
<pre:description>mydesc</pre:description>
<pre:creator>bjmann</pre:creator>
</inn:dublin-core>
</pre:root>
this may help...

Java.lang.NullPointerException javax.xml.parsers.DocumentBuilder.parse

Hi all,
i have a problem by solving an error in my code. The Code is mainly from Ian Darwin.
The code i am running works with j2sdk1.4.2_04. But now i have to bring it to work with jdk1.6.0_13.
The code parses xml documents. With small xml documents the code works. With large xml documents i get the following error while running the produced class file.
Exception in thread "main" java.lang.NullPointerException

I know what a java.lang.NullPointerException mens. But i don't know where i have to look for. Specially i don't know what or where "com.sun.org.apache...." is.
Is there a package that a have to add to the environment? Can some one tell my where i can find this package?
I wrote the code for some years ago, 2006 or so. With the knew jdk1.6.0_13 some thinks chance in the environment. Couldn't find what exactly.
The code has only 215 lines, but some how i can't add it to this Message, because Maximum allowed is only 7500.
Is there an other Forum, which may is better for my question?

DocumentBuilder parser, DOM doucment object from a XML file error

Hi guys
I created a program which parses a xml and creates a DOM document object from
it. The parser is validating.
class xmlParser
    //create arrylist to store employee in
    private ArrayList<Employee> employeeStore = new ArrayList<Employee>();
    private DocumentBuilder parser;
    private static Document document;
    //create an instant of Employee to be added to the arraylist
    private Employee theEmployee = new Employee();
    //create an instant of Address to be added to Employee to again be
    //added to Employee
    private Address employeeAddress = new Address();
    public xmlParser()
    public xmlParser(String myfile) throws IOException
          //validate the XML document agaisnt the given dtd
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setValidating(true);
          factory.setIgnoringElementContentWhitespace(true);
          try {
              parser = factory.newDocumentBuilder();
          }catch(javax.xml.parsers.ParserConfigurationException d) {
               System.out.println("error with new document builder");
          //create document object (DOM tree) from xml file
          try {
              document = parser.parse(new File(myfile));
          }catch(org.xml.sax.SAXException e) {
              System.out.println("Error with parser file still creating xml personnel2");
    } In my main method when i call:
xmlParser parsertree = new xmlParser("personnel.xml"); the exception keeps getting thrown and i get my my message back "Error with parser file still creating xml personnel2"
Can't seem to figure it out, any ideas would be great.
Thanks alot

Hi,
A - Check that the xml file is located in the same directory where you
run your app.
B - Check that the xml file is correct (in XML way).
Suggestion : you may print the exception message, it might help.
Hope that help,
Jack

DocumentBuilder.parse classpath problem

Hi, I've the "xerces.jar" in my classpath, and
I'm using it like this:
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.servlet.http.HttpServletRequest;
import org.xml.sax.helpers.DefaultHandler;
import org.xml.sax.SAXException;
//... etc..
Document mapDoc = null;
Element mapRoot = null;
try {
DocumentBuilderFactory docbuilderfactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder docbuilder = docbuilderfactory.newDocumentBuilder();
mapDoc = docbuilder.parse("/usr/home/tomsicp/site.xml");
//..... etc
The file compiles just fine, but when I run it on a
"SunOS 5.8 sun4u sparc, Ultra-60" I'm getting
"java.lang.NoClassDefFoundError: org/xml/sax/InputSource
at javax.xml.parsers.DocumentBuilder.parse(Unknown Source)
at <linenumber in my file>
When I run it on a "Linux 2.4.7-10smp #1"
everything is just fine.
I've got the exact same profile on both boxes, and the xerces.jar
file is exactly the same.
Any thoughts on why this is happening?
thanks,
Paul

XML newbie - parsing RSS

Hello Everbody,
i started playing around with xml and i am finding it very interesting...i have a question, how does one transform an rss feed using Java.(to use on my home page for example)? I know that they have an RSSUtilities package here on java.sun.com but i wanted to try it out on my own so that i get more experience using it..
i was successfully able to parse xml docs using sax and dom approaches..(i use jaxp by the way..) also, i can transform xml to html using dom and xslt stylesheets but feeds?? if i use the same program that i used for sml files, at run time i get the following errors..
Error: URI=file:D:/javapractice/inrss.xml Line=2: Element type "rss" is n
ot declared.
Error: URI=file:D:/javapractice/inrss.xml Line=2: Attribute "version" is

Error: URI=file:D://javapractice/inrss.xml Line=10: Element type "image" i

i think the above is understood because there is no dtd for these rss feeds... please, help me understand this as i am going crazy with this problem

Hi Nachida,
The code is very simple and I am posting it as below.. Please note that if I use a regular xml file, it gives me correct results but if I use an RSS feed, it complains..

                 dbFactory.setValidating(true);
                dbFactory.setIgnoringElementContentWhitespace(true);
                DocumentBuilder documentBuilder = dbFactory.newDocumentBuilder();
                document = documentBuilder.parse(new File("inrss.xml"));
          catch (SAXException e)
          {System.out.println("This is a SAX Exception");
          catch (ParserConfigurationException e)
          {System.out.println("This is a Parser Configuration Exception");
          catch (IOException e)
          {System.out.println("This is a IO Exception");
     public void transformTheDocument(File stylesheet)
          {try
               {Transformer transformer = TransformerFactory.newInstance().newTransformer(new                 StreamSource(stylesheet));
                transformer.transform(new DOMSource(document), new StreamResult( new File("alteredRss.html")));
          catch (TransformerConfigurationException e)
               {System.out.println("This a transformer configuration exception");
          catch (TransformerException e)
               {System.out.println(" this is a transformer exception");
     public static void main(String[] args) throws Exception
          {TransformRss transformRss = new TransformRss();
           transformRss.transformTheDocument(new File("program.xsl"));
Now instead of rss.xml if I want to transform lets say resumexml.xml it works fine... I am posting both resumexml.xml and inrss.xml
resumexml.xml-----------------------------------------------------------------------------------------

Has anybody used DocumentBuilder.parse(URL)

Hi friends
Has anybody used DocumentBuilder.parse(URL) for make document object.
I have the following piece of code
<code>
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
System.out.println("| Start | Fetch xml"); // ------------ 1
Document document = builder.parse("http://some url that gives back XML");
System.out.println("| Stop | Fetch xml"); // ------------- 2
</code>
Now the problem is .. once in a while the code will hang at point 1 and will never reach point 2. Exception handling has been done.. but there are no exceptions being logged. The code simply hangs.
Please let me know if you have also faced the same or similiar problem.
Thanking in anticipation
Partha.

Is it similar with a file URL instead a http URL.
Use
Document document = builder.parse("file://c:/xmlFile");
instead of
Document document = builder.parse("http://some url that gives back XML");

Make DocumentBuilder.parse ignore DTD references

Thanks to everyone in advance -
So this issue looks to be pretty popular, I have found a few solutions, but nothing seems to stop the downloading of dtd files, for instance ones sitting up on w3.org.
Here are some of the solutions i have found:
http://stackoverflow.com/questions/155101/make-documentbuilder-parse-ignore-dtd-references
http://forums.sun.com/thread.jspa?threadID=284209&forumID=34
When I use this solution:
myDocumentBuilder.setEntityResolver(new EntityResolver() {
          public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId)
                 throws SAXException, java.io.IOException
            if (publicId.equals("--myDTDpublicID--"))
              // this deactivates the open office DTD
              return new InputSource(new ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8'?>".getBytes()));
            else return null;
});it still continues to download the dtd.
Any suggestions?
Thanks,
Sam

                    MyDocumentBuilder.setEntityResolver(
                         new EntityResolver() {
                              public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId) throws SAXException, java.io.IOException {
                                   if(true){
                                        throw new IOException(publicId +"|"+ systemId);
                                   return null ;
                    );Good eye - It looks like that IOException is never being called - any suggestions?
Thanks,

Optimizing DocumentBuilder.parse ??

Hello,
I am loading XML files and am finding that once they get into the range of 500 kb or so they get really slow to load. I stuck in a bunch of timing statement and have found DocumentBuilder.parse(file) is the guitly party.
Does anyone know of any optimization possibilities for this or is this the nature of the beast? Is writing my own parser the only other option?
Thanks,
Shannon Goodman

Yes, the larger and more complex the XML the longer it takes to parse. But writing your own parser is not the only option (and if it were I would still recommend against it, because it's more complicated than you think). XML is designed so that you can use any parser you like, and the one you are using is not the only one available. Look for others and try them out.

Eastern European characters in XML and parsing

Hi all,
I have a problem with XML parsing within Java code with special Eastern European characters.
Whenever there is EE character within tags it reports:
WARNING (12847): CORE3283: stderr: org.xml.sax.SAXParseException: The element type "CodeMeaning" must be terminated by the matching end-tag "</CodeMeaning>".
at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:134)
Obviously special character is in CodeMeaning XML tag. XML is well formed and syntactically OK and without special characters works OK. Does anyone have any suggestion how to force special characters in XML?

Would you send a sample data for test? What is the encoding for your XML doc?

Variable xml and parser

I have a String containing xml code and i want to parse ths string
but method parse don't accept string so it returns "no protocol : String ".
Could you helpe please, it's very important.
my code (simplified):
String entete_xml="<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
String xml=entete_xml+"<aaa><bbb>aaaa</bbb><essai>reussi</essai></aaa>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
doc = builder.parse(xml);

builder.parse(new InputSource(new StringReader(xml)));

XML SAX parser that support LexicalHandler

Hello,
I'm looking for an XML SAX parser that support a LexicalHandler.
I have xml files that are not well formed, ie: (&, <, >, etc...) characters within tags and I need to ignore them.
Anyone have a link to some opensource library ??
Thanks,
Samir

Don't waste your time. Using a LexicalHandler isn't going to help with parsing malformed XML. You should get the person who produced those files to replace them with correct XML.

Using XDKs XML Schema Parser

I want to parse an XML schema(XSD file) and extract the types from it, ComplexType etc. Does anyone know to even begin this. Ive managed to parse and any XML file sucessfully returning all element types,names and values using the DOM parser but cant seem to find suitable methods in the oracle.xml.parser.schema library. I have started along these lines
XSDBuilder bob =new XSDBuilder();
XMLSchema sch = (XMLSchema)bob.build(url);
where URL is string referencing the xsd file. But after that all I can get is the targetnamespace using
String display = sch.getSchemaTargetNS();
Any help greatly appreciated.

Srinivas,
Thanks for the reply. But that is not my requirement.Suppose I have a schema representing the following xml
<Student>
<Name>ABC</Name>
<Class>XYZ</Class>
<Course>PQR</Course>
</Student>
When I parse the XML Schema representing the above XML, it should give me a Java object that represents this XML structure. (Similar to Document object that is obtained when we an XML is parsed)
Hope this is more clear.

XML C++ Parser in Solaris 2.6 could not parse with encoding UTF-16

I tried to use UTF-16 encoding in the XML C++ Parser in Solaris 2.6.
xmlinit() fails and returns error 201 - i.e.Unknown encoding. Though the ORACLE documentation has many encodings including UTF-16. Quite a few of these encodings are not working.
Can any one help about UTF-16.
Thanks
Vijay Kumar

Do you have Oracle's NLS data files?

XML C++ Parser in Solaris 2.6 could not parse with base64

I am using XML C++ Parser (version 2.0.4) in Solaris 2.6
I am using the following definition in dtd file to process binary data.
<!ELEMENT Agent (base64)>
I have two problem from xmlparse() function.
1. This declaration always produces a warning:
LPX-00103: warning: document structure does not match DTD.
2. This causes the parser to fail completely if the corresponding data is empty. This field needs to be optional.
Any ideas how to handle this situation.
Thanks in advance
Vijay Kumar

You can either turn off validation or read section 3.2 of http://www.w3.org/TR/1998/REC-xml-19980210 on how to write a proper DTD.
