Parse xml string not file

Hi
Can anyone help me I am trying to parse a xml file that is in a StringBuffer and not a file.
Any suggestions would be great.
Thanks ;>

You can create a StringReader object from your StringBuffer. Once you have a StringReader object, you can create an InputSource object. Then, you can parse the InputSource with a DocumentBuilder object. I enclosed the code to illustrate. The method printXml is only used to check that the XML string is properly parsed and retrieved.
import java.io.IOException;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

         StringReader strReader = new StringReader(yourStringBuffer.toString());
         //throws SAXException, IOException, IllegalArgumentException
         Document doc = docBuilder.parse(new InputSource(strReader));

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.

Create Business Partner from XMl String not a file

Hi,
Is it possible to create a BP from an XML string.
I know about GetBusinessPartnerFromXml(string FileName, int index)
but I dont want to save the string in a file before creating a BP from it
Hope there's a method to do that

Marc,
This looks like it is a duplicate of this post, so I am closing this thread as it looks like you answered your own question!

Parse XML Inbound Interface file

What are SAP best practices to parse XML Inbound Interface file?
Currently we are parsing XML Inbound file with custom ABAP code, but it is somewhat cumbersome and requires maintenance.
We do not any middleware that can parse file for us.
Is there is any best way we can handle this without lot of maintenance..

You can do it thro XLST..
Check this links..
Upload XML to internal table and vice versa in SAP 4.6C
/people/r.eijpe/blog/2005/11/10/xml-dom-processing-in-abap-part-i--convert-an-abap-table-into-xml-file-using-sap-dom-approach
YOu can do it through XLST. it is supported in ABAP from 4.7. you can create a XSLT, and read you XML, then CALL TRANSFORMATION to convert a XML into ABAP data structure.

How to convert information of a job posting into a xml string or file

hi hr experts,
I hope to find some answers.
Is there a function in the ERP system that converts all the information of a job posting into a xml string or file?
This could be used to communicate with external job databases, e.g. monster or jobpilot.
The function CALL TRANSFORMATION converts data to XML. Is this really the only way to convert the job posting?
Thanks for your feedback and help.

Hi Elena,
The issue is caused by XSLT is not script enabled by default. Please provide XsltSettings in the loading to fix the issue. For more information, please see:

Parsing xml string does not see the dtd inside jar

Hello,
I have problem parsing an XML string because the DTD file is not found (my DTD file is located inside my application's jar file). I am trying to instruct the parser where the DTD is located. If my DTD would have been on the filesystem directlly things would be working just fine, but i need to keep the DTD inside my JAR.
String dtdLocation = ClassLoader.getSystemResource("mydtd.dtd").toURI().toString();
Document xmlDocument = builder.parse(new ByteArrayInputStream(xmlFile.getBytes()),dtdLocation);The XML string looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Properties SYSTEM "mydtd.dtd">
<Properties>
<Prop>val<Prop>
</Properties>

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.

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

DocumentBuilder does not have a method parse with xml string as aparameter. The string should be a xml document uri.

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>
<b>
<result> valid some more tags here
</result>
</b>
<c> 10
</c>
</a>Edited by: geoman on Dec 8, 2008 2:30 PM

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.

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">

                               <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.

//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.

Passing / parsing XML String IN / OUT from PL / SQL package

Hello, People !
I am wondering where can I find exact info (with code sample) about following :
We use Oracle 8.1.6 and 8.1.7. I need to pass an XML String (could be from VARCHAR2 to CLOB) from VB 6.0 to PL/SQL package. Then I need to use built in PL/SQL XML parser to parse given string (could be large hierarchy of nodes)
and the return some kind of cursor thru I can loop and insert data into
different db Tables. (The return value may have complex parent/child data relationship - so I am not sure If this should be a cursor)
I looked online many site for related info - can't find what I am looking
for - seems like should be a common question.
Thanx a lot !
