How to parse xml string

Hi! I'm having problems parsing an xml string. I've done DOM and SAX parsing before. But both of them either parse a file or data from an input source. I don't think they handle strings. I also don't want to write the string into a file just so I can use DOM or SAX.
I'm looking for something where I could simply do:
Document doc = documentBuilder.parse( myXMLString );
So the heirarchy is automatically established for me. Then I could just do
Element elem = doc.getElement();
String name = elem.getTagName();
These aren't the only methods I would want to use. Again, my main problem is how to parse xml if it is stored in a string, not a file, nor comming from a stream.
thanks!

But both of them either parse a file or data from an input source. I don't think they handle strings.An InputSource can be constructed with a Reader as input. One useful subclass of Reader is StringReader, so you'd use something likeDocument doc = documentBuilder.parse(new InputSource(new StringReader(myXMLString)));

How to parse XML string fetched from the database

i want to parse the XML string which is fetched from the oracle database.
i have inserted the string in xml format in the database. The type of the field in which it is inserted is varchart2.
I am successfully getting it using jdbc, storing it in a String.
Now it is appended with xml version 1.0 and string is ready for parsing.
Now i am making following programming.
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = Builder.parse(xmlString);
Element root = doc.getDocumentElement();
NodeList node = root.getElementsByTagName("product");
But i am getting IOException at the statement
Document doc = Builder.parse(xmlString);
there fore i request u to kindly help me in solving this error.
-regards
pujan

DocumentBuilder does not have a method parse with xml string as aparameter. The string should be a xml document uri.
Convert xml string to StringReader.
parse(new InputSource(new StringReader(xmlString)));

Help: How to parse XML string into Node Context

Hi Experts,
I am trying to work with a web dynpro for java application which calls a Web Service. I can call the web service successfully, however I have a problem on interpreting the response result into table. The response result is in (XML) string format, like this:
I followed this , but it resulted to an error:
com.sap.engine.lib.xml.parser.NestedSAXParserException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: Name expected: 0x20(:main:, row:158, col:59)(:main:, row=158, col=59) -> com.sap.engine.lib.xml.parser.ParserException: Name expected: 0x20(:main:, row:158, col:59)
do anyone of you had a similar experience and were able to resolve it, please post it here. it will be highly appreciated. thanks in advance.

Try this :
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new org.xml.sax.InputSource(new StringReader(strXml)));Hope this helps.

How to parse XML against XSD,DTD, etc.. locally (no internet connection) ?

i've searched on how to parse xml against xsd,dtd,etc.. without the needs of internet connection..
but unfortunately, only the xsd file can be set locally and still there needs the internet connection for the other features, properties.

Thanks a lot Sir DrClap..
I tried to use and implement the org.w3c.dom.ls.LSResourceResolver Interface which is based on the SAX2 EntityResolver.
please give comments the way I implement it. Here's the code:
LSResourceResolver Implementation
import org.w3c.dom.ls.LSInput;
import org.w3c.dom.ls.LSResourceResolver;
import abc.xml.XsdConstant.Path.DTD;
import abc.xml.XsdConstant.Path.XSD;
public class LSResourceResolverImpl implements LSResourceResolver {
     public LSResourceResolverImpl() {
      * {@inheritDoc}
     @Override
     public LSInput resolveResource(String type, String namespaceURI, String publicId, String systemId, String baseURI) {
          ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
          LSInput input = new LSInputImpl(publicId, systemId, baseURI);
          if ("http://www.w3.org/2001/xml.xsd".equals(systemId)) {
               input.setByteStream(classLoader.getResourceAsStream(XSD.XML));
          } else if (XsdConstant.PUBLIC_ID_XMLSCHEMA.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.XML_SCHEMA));
          } else if (XsdConstant.PUBLIC_ID_DATATYPES.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.DATATYPES));
          return input;
}I also implement org.w3c.dom.ls.LSInput
import java.io.InputStream;

public class LSInputImpl implements LSInput {
     private String publicId;

     private String stringData;
     public LSInputImpl(String publicId, String systemId, String baseURI) {
          super();
          this.publicId = publicId;
          this.systemId = systemId;
          this.baseURI = baseURI;

How to parse XML for internal table

hi guys, I would like to know how to parse xml for an internal table. I explain myself.
Let's say you have a purchase order form where you have header data & items data. In my interactive form, the user can change the purchase order quantity at the item level. When I received back the pdf completed by mail, I need to parse the xml and get the po qty that has been entered.
This is how I do to get header data from my form
lr_ixml_node = lr_ixml_document->find_from_name( name = ''EBELN ).
lv_ebeln = lr_ixml_node->get_value( ).
How do we do to get the table body??
Should I used the same method (find_from_name) and passing the depth parameter inside a do/enddo?
thanks
Alexandre Giguere

Alexandre,
Here is an example. Suppose your internal table is called 'ITEMS'.
lr_node = lr_document->find_from_name('ITEMS').
lv_num_of_children = lr_node->num_children( ).
lr_nodechild = lr_node->get_first_child( ).
do lv_num_of_children times.
    lv_num_of_attributes = lr_nodechild->num_children( ).
    lr_childchild = lr_nodechild->get_first_child( ).
   do lv_num_of_attributes times.
      lv_value = lr_childchild->get_value( ).
      case sy-index.
         when 1.
           wa_item-field1 = lv_value
         when 2.
           wa_item-field2 = lv_value.
      endcase.
      lr_childchild = lr_childchild->get_next( ).
   enddo.
   append wa_item to lt_item.
   lr_nodechild = lr_nodechild->get_next( ).
enddo.

Spry can not parse xml string

while designind an mvc architecutre in php I found display
data on site was slow so I generate a xml sheet an used spry Data
loading was fast an dproduced and I also performed many operations
like sorting ,galeery making ..etc... but main thing is that I can
not parse a xml string using spry only a xml file can be parsed
my application required to parse xml string

I'm not sure if this is valid in your situation, but OC4J comes with Oracle XMLParser.
Simply use the JAXP API to parse/build/modify XML and the Oracle XMLParser implementation will be used behind the scenes.
If you must use xerces/xalan, try putting the jars in OC4J_HOME/j2ee/home/lib instead.

Hi Mandya,
This is outside of the normal use case for TestStand. It would be best to use a code module (developed in LabVIEW, C, or any other language) to accomlish this and then call it from a step in TestStand. You can find examples on ActiveX here:

There are lot of Java XML parsing API's available, e.g. JAXP, DOM4J, JXPath, etc.
Of course you can also write it yourself. Look which methods the String API offers you, e.g. substring and *indexOf.

JDOM: Parsing XML String, getting error

Hello,
I am new to this forum, so please forgive me
if this has already been asked before. I want to
parse an XML string. I know the JDOM parser works
great with a file, but apparently I have been
unsuccessful parsing an XML String. Below is how I
initialize the parser:
import java.io.*; //Import proper packages
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.output.*;
import java.util.*;
import java.lang.*;
public class XMLParser{
private Document doc = null;
public XMLParser(String xml){
doc = readDocument(xml);
private Document readDocument(String xml) {
try {
SAXBuilder builder = new SAXBuilder();
org.jdom.Document result = builder.build(new
StringReader(xml));
return result;
} catch(JDOMException e) {
e.printStackTrace();
} catch(NullPointerException e) {
e.printStackTrace();
return null;
} //readDocument
The following is the error I receive:
JDOM/xmlparser.java [81:1] cannot resolve symbol
symbol : method build (java.io.StringReader)
location: class org.jdom.input.SAXBuilder
org.jdom.Document result = builder.build(new
StringReader(filename));
--> Arrow pointing to builder.build
Please if someone can help me out. If JDOM does not
have this feature, then can someone please recommend a
parser that can parse an XML String.

Thank you for your help, although it seems like it was JDom 9 beta. When I tried with JDOM 8 beta, everything worked fine even with the StringReader. So if anyone is having similar problems with JDom 9 then try with JDom 8.
