XML string parsing

Is there any class method to parse an XML string into tags and contents?
I have a response in XML and would like to read a tags contents.
Thanks

Hi KP,
look at the iXML library. http://help.sap.com/saphelp_nw04/helpdata/en/47/b5413acdb62f70e10000000a114084/frameset.htm
Depending what release you are developing on you might also want to look at SImple Transformations.

Getting Error while creating Document object after parsing XML String

Hi All,

XML string to XML parsing in JCD

I have stored an XML file as a CLOB in the Oracle DB. While fetching this data into JCD using Oracle OTD, I am getting this CLOB field as a string containing the XML. Now I want to parse this XML string to XML, as I need to map the individual fields to an XSD OTD, which will be my output.
Kindly suggest a way to achieve this.

An XSD OTD has an unmarshalFromString() method:
inputFormat.unmarshalFromString( strData );
When putting the XML into the CLOB it could be a good idea to wrap an outputstream into a Writer object in order to make certain that the encoding is correct, depending how the data is represented. When retrieving CLOB data using getCharacterStream() you will get a Reader object where the encoding is already given.

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)));

inStream.setCharacterStream(new StringReader(xmlstring));
Document doc1 = db.parse(inStream);
I notice that all the values i set in XML are available in the doc1 field. But I was not able to get them as a string..
Can Some one tell me how to get the attributes out of the doc1? I tried getElementBytag and other options.. Do i need to take out the tag items in the sequence in which they are given? or can i select a tag random and pick up the attributes??
Plzz help me out!!

Hope this helps you, let me know.

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.

Parsing an xml string into id-value pair format

Hi,
I am new in oracle BPEL.
My requirement is that I need to parse an xml string containing tag name and coressponding value into an 'id -value' pair.
For example-
The input xml format is -
<employee>
<empid>12345</empid>
<name>xyz</name>
<city>London</city>
</employee>
The required xml format is-
<employee>
<item id="empid" value="12345"/>
<item id="name" value="xyz"/>
<item id="city" value="London"/>
</employee>
Please let me know if there is a work-around for this.
Thanks

Something like this (have not tested):
<xsl:for-each select="//employee">
<employee>
<xsl:for-each select="./*">
<item>
<xsl:attribute name="id">
<xsl:value-of select="name()"/>
</xsl:attribute>
<xsl:attribute name="value">
<xsl:value-of select="text()"/>
</xsl:attribute>
</item>
</xsl:for-each>
</employee>
</xsl:for-each>

Parsing an XML string

How would I get the Oracle XML Parser to parse an XML string?
The example ("DOMSample") only demonstrates how to parse an XML
file -- I would like to do something of the form...
parser.parse("<test>testing</test>");
On a related note, whilst the PL/SQL utilities are helpful, I
would like to see more in the way of documentation and examples
for the Parser itself, showing more examples of DOM API calls and
perhaps a complete worked example (including a DTD).
Keep up the good work!
Many thanks,

With the latest version, 1.0.0.1, now available, you can use the
InputStream and InputSource methods. Please see the doc for
details.

Parsing XML string with XPath

Hi,-
I am trying to parse an XML string with xpath as follows but I am getting null for getresult.
I am getting java.xml.xpath.xpathexpressionexception at line where
getresult = xpathexpression.evaluate(isource); is executed.
What should I do after
xpathexpression = xPath.compile("a/b");in the below snippet?
Thanks
String xmlstring ="..."; // a valid XML string;
Xpath xpath = XPathFactory.newInstance().newPath();
xpathexpression = xPath.compile("a/b");
// I guess the following line is not correct
InputSource isource = new inputSource(new ByteArrayInputStream(xmlstring.getBytes())); right
getresult = xpathexpression.evaluate(isource);My xml string is like:
<a>

<result> valid some more tags here
</result>

<c> 10
</c>

I've never used the version of evaluate that takes an InputSource. The difficulty with using it is that it does not save the DOM object. Each expression you evaluate will have to create the DOM object, use it once and then throw it away. I've yet to write a program that only needs one answer from an XML document. Usually, I use XPath to locate somewhere in a document and then read "nearby" content, add new content nearby, delete content, or move content. I'd suggest you may want to parse the XML stream and save the DOM Document.
Second, all of the XPath expressions search from a "context node". I have not had good luck searching from the Document object, so I always get the root element first. I think the expression should work if you use the root as the context node. You will need one of the versions of evaluate that uses an Object as the parameter.

How to Parse an XML string

I need some help to parse an XML String instead of an XML file. The string can be like.
String myRecords =
"<data>"+
" <employee>"+
" <name>John</name>"+
" <Designation>Manager</Designation>"+
" </employee>"+
" <employee>"+
" <name>Sara</name>"+
" <Designation>Clerk</Designation>"+
" </employee>"+
"<data>"+

I tried it in a servlet, it and it worked. The entire code is long. But here it is most of it:
assuming that x is a string and has the xml of
<?xml version="1.0" ?>
- <company>
- <employee>
<firstname>Tom</firstname>
<lastname>Cat</lastname>
</employee>
- <employee>
<firstname>Paul</firstname>
<lastname>Enderson</lastname>
</employee>
- <employee>
<firstname>George</firstname>
<lastname>Jungle</lastname>
</employee>
</company>
=========================
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
InputSource inStream = new InputSource();
inStream.setCharacterStream(new StringReader(*x*));
Document doc = db.parse(inStream);
doc.getDocumentElement().normalize();
out.println("Root element " + doc.getDocumentElement().getNodeName() + " ");
NodeList nodeLst = doc.getElementsByTagName("employee");
out.println("Information of all employees ");
for (int s = 0; s < nodeLst.getLength(); s++) {
Node fstNode = nodeLst.item(s);
if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
Element fstElmnt = (Element) fstNode;
NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("firstname");
Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
NodeList fstNm = fstNmElmnt.getChildNodes();
out.println("First Name : " + ((Node) fstNm.item(0)).getNodeValue() + " ");
NodeList lstNmElmntLst = fstElmnt.getElementsByTagName("lastname");
Element lstNmElmnt = (Element) lstNmElmntLst.item(0);
NodeList lstNm = lstNmElmnt.getChildNodes();
out.println("Last Name : " + ((Node) lstNm.item(0)).getNodeValue() + " ");
} catch (Exception e) {
System.out.println(e);
out.close();
==============
The output is
Root element company
Information of all employees
First Name : Tom
Last Name : Cat

Problem in parsing a xml string using dom parser

i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........

i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs.

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)));

Getting null value while parsing "XML String" with encoding WINDOWS-1252.

Hi,
when I am converting the Follwoing "xml string " to Document, I am getting the "null" as a document value.
 String strXML = "<?xml version="1.0" encoding="WINDOWS-1252"?>
 <category name="SearchByAttributes" value="Search By Attributes">
 <item name="ORDER_LINE_ID" description="Application Search Attributes" >
 <attribute name="Sequence" value="0001"/>
 </item>
 </category>"
My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
 String strXML = //my above string xml.
 DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
 docBuilderFactory.setIgnoringElementContentWhitespace(true);
 docBuilder = docBuilderFactory.newDocumentBuilder();
 doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
 System.out.println("doc value.."+doc)//I am getting null value for "doc".
Can anyone help me to resolve the issue.

System.out.println("Element Attibrute list....."+elementAtt);
//getting Element Attribute list as an...."null"(I am expecting output value object reference but it is printing "null"
(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums.
