StringReader problem in CLDC to parse String XML

hello..
i'm newbie in java mobile...
i have problem to parse my XML string to my web service..
i had develop client mobile to access my web service with KSOAP2, and in the first time, i devlop in CDC not CLDC, so there is no problem when i use some of java.io, i use java.io.StringReader to parse my string XML...
the code i use in CDC when using java.io.StringReader is like this :
XmlPullParser parser = new KXmlParser();
String a = "<n1:ClientHeader xmlns:n1=\"http://www.myweb.web.id\">" +
 "<n1:ClientUser>" + client.user + "</n1:ClientUser>" +
 "<n1:ClientIP>" + client.ip + "</n1:ClientIP>" +
 "</n1:ClientHeader >";
parser.setInput(new StringReader(a));
Document doc = new Document();
doc.parse(parser);
Element headSoap = new Element();
headSoap = doc.getRootElement(); then, i use this code in CLDC, the error was found, becouse java.io.StringReader in CLDC not found.
so, my question is ...
any solution to solve my problem when i have string which the value is in XML, like in my code before, and i want to parse it to kxml2.kdom.Element, how..?
please help me...

Parsing String XML Document

I didn't find a method that parses a XML document when it's not a file. I have a String that I want to parse and the method DocumentBuilder.parse only accepts a String that is a uri to a file.
I write this code:
String strXML = "<?xml version='1.0' ?><root><node>anything</node></root>";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
domDoc = docBuilder.parse(strXML);
Please gimme a light!!

I have a similar problem, I'm trying to do the same BUT in a servlet, it compiles and it actually works if I use it outside my servlet, but, when I mount the servlet with the code similar to this one here it doesn't read the string (at least that's what appears to be, because it doesn't writes to my DB as it should and it doesn't display anything as I'm specifying as my servlet response). Any help? I'm posting my code here:

Not able to parse string-xml through parseEscapedXml

Hi all,
What I am doing is, I am getting some data through polling and populating a schema variable. Because of having extra namespace in the resultant xml, I again used processXSLT and assigned the resultant xml to a string variable (after converting it to string).
Now I want to pass this string to my web service. When I tried the
ora:parseEscapedXML(ora:getContentAsString(bpws:getVariableData('niku_xog_project_write_xml_as_string')))
It is giving the xpath error ORABPEL-09500. However when I remove the parseEscapedXML function, I am able to see the correct data on server. But it doesn't work because web-service expecting the xml instead of string.
Below is the xml in string format. I picked it from server log.

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.

Parse an XML String

hi lets say i got an XML String which looks like this..
String xmlstring = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><GET_REALIZED_GAIN_LOSS_DETAIL_RESPONSE xsi:schemaLocation=\"http://www.statementone.com/webservice/schemas D:\\PMTSchema.xsd\" xmlns=\"http://www.statementone.com/webservice/schemas\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><STATUS>true</STATUS><ERRORS><ERROR><TYPE>String</TYPE><MESSAGE>String</MESSAGE><ERROR_ID>1</ERROR_ID></ERROR><ERROR><TYPE>String</TYPE><MESSAGE>String</MESSAGE><ERROR_ID>1</ERROR_ID></ERROR></ERRORS><GET_REALIZED_GAIN_LOSS_RESULT><XYZ>String</XYZ></GET_REALIZED_GAIN_LOSS_RESULT></GET_REALIZED_GAIN_LOSS_DETAIL_RESPONSE>";
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
InputSource inStream = new InputSource();
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.

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
First Name : Paul
Last Name : Enderson
First Name : George
Last Name : Jungle

Problem in parsing an XML using SAX parser

Hai All,
I have got a problem in parsing an XML using SAX parser.
I have an XML (sample below) which need to be parsed
<line-items>
<item num="1">
 <part-number>PN1234</part-number>
 <quantity uom="ea">10</quantity>
 <lpn>LPN1060</lpn>
 <reference num="1">Line ref 1</reference>
 <reference num="2">Line ref 2</reference>
 <reference num="3">Line ref 3</reference>
</item>
<item num="2">
 <part-number>PN1527</part-number>
 <quantity uom="lbs">5</quantity>
 <lpn>LPN2152</lpn>
 <reference num="1">Line ref 1</reference>
 <reference num="2">Line ref 2</reference>
 <reference num="3">Line ref 3</reference>
</item>
<item num="n">
</item>
</line-items>
There can be any number of items( 1 to n). I need to parse these
item values using SAX parser and invoke a stored procedure for
each item with its
values(partnumber,qty,lpn,refnum1,refnum2,refnum3).
Suppose if there are 100 items, i need to invoke the stored
procedure sp1() 100 times for each item.
I need to invoke the stored procedure in endDocument() method of
SAX event handler and not in endelement() method.
What is the best way to store those values and invoke the stored
procedure in enddocument() method.
Any help would br greatly appreciated.
Thanks in advance
Pooja.

VO or ValueObject is a trendy new name for Beans.
So just create an item class with variables for each of the sub elements.
<item>
<part-number>PN1234</part-number>
<quantity uom="ea">10</quantity>
<lpn>LPN1060</lpn>
<reference num="1">Line ref 1</reference>
<reference num="2">Line ref 2</reference>
<reference num="3">Line ref 3</reference>
</item>
public class ItemVO
String partNumber;
int quantity;
String quantityType;
String lpn;
List references = new ArrayList();
* @return Returns the lpn.
public String getLpn()
return this.lpn;
* @param lpn The lpn to set.
public void setLpn(String lpn)
this.lpn = lpn;
* @return Returns the partNumber.
public String getPartNumber()
return this.partNumber;
* @param partNumber The partNumber to set.
public void setPartNumber(String partNumber)
this.partNumber = partNumber;
* @return Returns the quantity.
public int getQuantity()
return this.quantity;
* @param quantity The quantity to set.
public void setQuantity(int quantity)
this.quantity = quantity;
* @return Returns the quantityType.
public String getQuantityType()
return this.quantityType;
* @param quantityType The quantityType to set.
public void setQuantityType(String quantityType)
this.quantityType = quantityType;
* @return Returns the references.
public List getReferences()
return this.references;
* @param references The references to set.
public void setReferences(List references)
this.references = references;

Can someone help me with a problem of parsing an XML file?

Hello,
I'm having some problems parsing an xml file. I get a SAXNotSupportedException when setting a property value.
Here is the piece of code where I have the problem:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
SAXParser saxParser = spf.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
DefaultHandler defHandler = new DefaultHandler();
xmlReader.setProperty("http://xml.org/sax/properties/lexical-handler", defHandler);
and the log is:
Problem with the parser org.xml.sax.SAXNotSupportedException: PAR012 For propertyID "http://xml.org/sax/properties/lexical-handler", the value "org.xml.sax.helpers.DefaultHandler@4ff4f74a" cannot be cast to LexicalHandler.
http://xml.org/sax/properties/lexical-handler org.xml.sax.helpers.DefaultHandler@4ff4f74a LexicalHandler
I've been working on this problem but I can't find the error.
Does anyone have an idea of what to do to solve it?
Thanx in advance,
M@G

before deciding which XML technology to use, you should see if your application fit in the category below:
use SAX:
1. The XML file is rather large (30 or 40+ MB)
2. I don't need the xml document in memory. I will parse the document and store the data in my own object.
use DOM or JDOM
1. The XML file is relatively small (less than 30 MB) or I can increase the runtime memory for larger xml file.
2. I will need to walk up and down the xml document tree severals time.
3. My application is in Java and it's not going to be rewritten in C++, etc (use JDOM)
NOTE:
JDOM is rather easier to use (for Java developer), but it's not an www.org.com standardlized xml parser.
personally, i like JDOM for traversing the DOM.

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.

Problem in parsing huge XML document

Hi,
i am getting the problem when trying to parse xml doc. which contains data more then 1 lacs. using jaxp (i.e. NodeList). i get the execption outofmemory.

Which implementation of JAXP are you using? If it is a large file containing many of the same "documents", then consider using SAX as it is an event driven parser meaning it does not have to read the whole of the file before it can start processing it. Instead, it fires events when it sees the beginning and end of a "document" and also on completion of the elements. You can then create and destroy objects during the document processing stage which helps keep the memory consumption under control.

How to parse whole xml elements into a java String

hello everybody,
I am trying to parse whole xml into a string for example
my xml file is as below:
<root>
 <element>
 <data id="1">1</data>
 </element>
 <element>
 <data id="2">2</data>
 </element>
</root>
in java whole data should be transfered as
String xmlString ="<root><element><data id=\"1\">1</data></element><element><data id=\"2\">2</data></element></root>";or in a simple way can xml be copied into a string? any assistance ...
thanQ in Advance.
Han.

This code is to convert xml document to a string.
 try {
 javax.xml.transform.TransformerFactory tfactory = TransformerFactory.newInstance();
 javax.xml.transform.Transformer xform = tfactory.newTransformer();
 javax.xml.transform.Source src = new DOMSource(xmlString);
 java.io.StringWriter writer = new StringWriter();
 StreamResult result = new javax.xml.transform.stream.StreamResult(writer);
 xform.transform(src, result);
 //System.out.println(writer.toString());
 } catch (TransformerConfigurationException e) {
 e.printStackTrace();
 }catch(Exception ex )
 ex.printStackTrace();
 }

Parsing a XML file using Jdom-Problem.

Hi all,
I am reposting it as I was told to format the code and send it again.
I am trying to parse a xml file using a jdom java code.This code works fine if I remove xmlns attribute in the root element. (I get the expected result) .If the "xmlns" attribute is put in the xml as it should be then the parsing and retrieving returns null. Please tell me how to fix this issue.

// create a XML parser and read the XML file
SAXBuilder oBuilder = new SAXBuilder();
Document oDoc = oBuilder.build(new File("**xml file location**"));
Element root = oDoc.getRootElement();
System.out.println(root.getName());
String tgtns= root.getAttributeValue("targetNamespace");
System.out.println("tgt ns "+ tgtns);
List list= root.getChildren("partnerLinks");
Iterator it1= list.iterator();
System.out.println("Iterator 1 - "+list.size());
while(it1.hasNext()){
Element partnerlinks = (Element)it1.next();
List list2= partnerlinks.getChildren("partnerLink");
System.out.println("iterator 2 - "+list2.size());
}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Result:
Without Xmlns in xml file(Expected and correct output)
process
tgt ns http://serena.com/CreateKBEntryService
Iterator 1 - 1//expected and correct result that comes when I remove xmlns attribute from xml
iterator 2 - 2
Result with xmlns:
process
tgt ns http://serena.com/CreateKBEntryService
Iterator 1 - 0 //instead of 0 should return 1

LOL
This is what you get for working 12 hours straight....
I changed:
xmlObject["mydoc"]["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"] 
to:
#mydoc["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"]# 
xmlObject is the name of my xml object in memory, and then you reference from the root of the xml doc down the chain.
Sorry for the inconvenience,
Rich
