How to parse XML content in JMS Message...
Hi everybody,
I am currently developing a Message-Driven Bean and has some problem parsing the XML data that contains in the JMS body.
The XML data is contained in TextMessage (JMS message type) and in order to parse the data, I need to use the DOM builder, which is expecting to read from a file (e.g. abc.xml).
My question is how can I use TextMessage (can be output to a String) as the input source instead of a file.
Thanks in advance.

What about this:
DocumentBuilder db = ...
Document doc = db.parse(new InputSource(new
StringReader(textMessage.toString()));
or
Document doc = db.parse(new
ByteArrayInputStream(textMessage.toString().getBytes()));

Does JMS parse xml content in TextMessages
Hi
I am working on WLS 6.1sp2 and I am using jms TextMessage type of message to
send XML messages from one subsystem to another. I have added an XML registry
for my version of XML parser. Now I do not have any entries for the entity declarations
nor for the parser entries in the registry.
When I send in an XML message in a TextMessage envelope I find the following
errors in the log.
<Jun 9, 2003 3:56:57 PM PDT> <Error> <XML> <Failed to parse given XML document.
Failed to retrieve PUBLIC id. The root element is required in a well-formed docu
ment.>
<Jun 9, 2003 3:56:57 PM PDT> <Error> <XML> <Failed to open XML document. Failed
to retrieve PUBLIC id or SYSTEM id from the document. Decrease the number of cha
r between the beginning of the document and its root element.>

<Jun 9, 2003 3:56:57 PM PDT> <Error> <XML> <Failed to parse given XML document.
Failed to retrieve PUBLIC id. The root element is required in a well-formed docu
ment.>
Now from the logs I understand that the message is being parsed and since the
parser does not find any PUBLIC ID or SYSTEM id it dumps the error, since I am
using schemas there is none of the PUBLIC and SYSTEM ids in my xml, also this
is not logged by any component of my subsystems, this is a weblogic XML Service
log and when I trace through the code I find that it comes up after the first
subsystem sends the message and before the second subsystem receives it.
The question then is does JMS parse XML content in TextMessages and if so how
can I disable that parsing?
Thanks
Sandeep
JMS does not automatically parse TextMessages. Check the XML declaration in
your application's deployment descriptors. That's often the source of this
error.
FYI, you can use XMLMessage for xml payloads. As far as I can remember, the
XMLMessage is an extension of the TextMessage with xml parsing built in.

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 GiguereAlexandre,
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. -

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;
import java.io.Reader;
import org.w3c.dom.ls.LSInput;
public class LSInputImpl implements LSInput {
private String publicId;
private String systemId;
private String baseURI;
private InputStream byteStream;
private String stringData;
public LSInputImpl(String publicId, String systemId, String baseURI) {
super();
this.publicId = publicId;
this.systemId = systemId;
this.baseURI = baseURI;
//getters & setters
}Then, here's the usage/application:

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)));

Regards,
Menaka.H.BHello,
For how to get the node name, you have to refer to this :
[https://wiki.sdn.sap.com/wiki/display/ABAP/Upload%20XML%20file%20to%20internal%20table|https://wiki.sdn.sap.com/wiki/display/ABAP/Upload%20XML%20file%20to%20internal%20table]
Check the code after:
WHEN if_ixml_node=>co_node_element
It tells you how to get the node name.

How to parse xml and import to execel
pls let me know how to parse XML file and import all data to execel sheet.
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:

How to read XML content from IPortalComponentRequest and parse them
Hi ,
I have a portal application.The application has 2 components(Comp1,comp2).
Comp1 is JspDynpage and Comp2 is AbstractPortalComponent.
Comp1- has a iframe element which point to the external url and has a parameter return_url.
retrun_url has a value as url to Comp2(http://ibm0343:50000/irj/servlet/prt/portal/prtroot/NewUrlProj.NewUrlComp)
When an event occurs in the external site,i suppose to receive XML content in return_url(ie Comp2),how can i check using the request if the received content is XML and how do i parse them.
I have already seen blogs from Prakash singh in which it refers a xml fixed location in webserver.Hi Detlev,
i am reposting this once again as the previous
reply didnt align good.
Thanks for your reply.The scenario is that
My portal application has to communicate with external GIS(Graphical information system)
service provider client application.
They say that i have to use iframe in my portal application.
Here is the snipet of the iframe tags.
<iframe

When my portal application is started, comes the GIS map in the iframe with in my portal application.
When the user clicks in the area of the map,Gis application returns xml data to the return_url.
The reurn_url is my PortalAbstractComponent in which i have to parse the xml and use it for further processing in R3 system. -

System.out.println("elName.geText() = " + room.getText(j));
else if (room.getName().equals("Name")) {
System.out.println("elName.getName() = " + room.getName());
System.out.println("elName.geText() = " + room.getText(j));
} // end for(int j...)
} // end if (root.getType(i)
} //for (int i...)
The problem is that I don't know how to get the values out of the tags:
<ID>1</ID>
<Name>Rum 101</Name>
<Type>Dubbelrum</Type>
<NumberOfBeds>2</NumberOfBeds>
<Rate>980,00</Rate>
<Currency>SEK</Currency>
<Description>Ett genomtrevligt rum</Description>
It's no problem to get the value from the firsts i.e. <ID> but I don't know how to get the value from <Name> ... <Description>. I have looked att examples but I don't understand how to do this. Can someone please help me =)okay, sorry, I only read the half of your problem ;-)
You can read the content using the getText(0) method. the 0 indicates the number of the children which you want to get. That is always a 0 because you have always just one text-children in your text-tags. The content is again a children of type text!

How to Parse XML with SAX and Retrieving the Information?
Hiya!
I have written this code in one of my classes:
/**Parse XML File**/
SAXParserFactory factory = SAXParserFactory.newInstance();
GameContentHandler gameCH = new GameContentHandler();
try
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(recentFiles[0], gameCH);
catch(javax.xml.parsers.ParserConfigurationException e)
e.printStackTrace();
catch(java.io.IOException e)
e.printStackTrace();
catch(org.xml.sax.SAXException e)
e.printStackTrace();
/**Parse XML File**/
games = gameCH.getGames();And here is the content handler:
import java.util.ArrayList;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
class GameContentHandler extends DefaultHandler
private ArrayList<Game> games = new ArrayList<Game>();
public void startDocument()
System.out.println("Start document.");
public void endDocument()
System.out.println("End document.");
public void startElement(String namespaceURI, String localName, String qualifiedName, Attributes atts) throws SAXException
public void endElement(String namespaceURI, String localName, String qualifiedName) throws SAXException
public void characters(char[] ch, int start, int length) throws SAXException
/**for (int i = start; i < start+length; i++)
System.out.print(ch);
public ArrayList<Game> getGames()
return games;
}And here is the xml i am trying to parse:<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<Database>
<Name></Name>
<Description></Description>
<CurrentGameID></CurrentGameID>
<Game>
<gameID></gameID>

<update></update>
<mods></mods>
<guide></guide>
<walkthrough></walkthrough>
<cheats></cheats>
<savegame></savegame>
<completed></completed>
</Game>
</Database>I have been trying for ages and just can't get the content handler class to extract a gameID and instantiate a Game to add to my ArrayList! How do I extract the information from my file?
I have tried so many things in the startElement() method that I can't actually remember what I've tried and what I haven't! If you need to know, the Game class instantiates with asnew Game(int gameID)and the rest of the variables are public.
Please help someone...OK, how's this?
public void startElement(String namespaceURI, String localName, String qualifiedName, Attributes atts) throws SAXException
current = "";
public void endElement(String namespaceURI, String localName, String qualifiedName) throws SAXException
try
if(qualifiedName.equals("Game") || qualifiedName.equals("Database"))
{return;}
else if(qualifiedName.equals("gameID"))
{games.add(new Game(Integer.parseInt(current)));}
else if(qualifiedName.equals("name"))
{games.get(games.size()-1).name = current;}
else if(qualifiedName.equals("publisher"))
{games.get(games.size()-1).publisher = current;}
etc...
else
{System.out.println("ERROR - Qualified Name found in xml that does not exist as databse field: " + qualifiedName);}
catch (Exception e) {} //Ignore
public void characters(char[] ch, int start, int length) throws SAXException
current += new String(ch, start, length);

How to parse XML files from normal FTP Servers?
I want to parse xml files from a normal FTP Servers , NOT the sap application severs itself. How can i do that?
I know how to use the SAPFTP getting and putting files ,but I don't want to download and then parse it.
