How to Parse XML into String in BPEL?

Hi,
Can anyone tell me, how can I parse XML into String?
I am taking input from File Adapter, File adapter is reading that XML.
Then in assign activity i am using XPath expression(built functions) using XMLParser(),doTranslateToNative() etc.. many functions I have tried but XML is not getting parsed into String Variable.
Please help me asap.
Thanks
Shikha

Thanks a lot Eric.
I am trying this, oraext:get-content-as-string('receiveInput_Read_InputVariable','body','/ns3:orders')
but getting this error
<bpelFault><faultType>0</faultType><subLanguageExecutionFault xmlns="http://schemas.oracle.com/bpel/extension"><part name="summary"><summary>XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is oraext:get-content-as-string('receiveInput_Read_InputVariable','body','/ns3:orders').

 <FileName>FileName123</FileName>
 <Type/>
 < TemplateName/>
 </DrawingSpecification>
 <Image contentType=""/>
 < /Drawing>
Output should be like:
 < File>

what about something like this
package test;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
public class Test {
 public static void main(String args[]) throws Exception {
 DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
 DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
 Document doc = docBuilder.parse(new File("test.xml"));
 StringBuffer buffer = new StringBuffer();
 appendChildren(buffer, doc.getChildNodes());
 System.out.println(buffer.toString());
 private static void appendChildren(StringBuffer buffer, NodeList list) {
 for (int i = 0; i < list.getLength(); i++) {
 Node node = list.item(i);
 if (node.getNodeValue() != null) {
 if (node.getNodeValue().trim().length() > 0) {
 buffer.append(node.getNodeValue()).append("|");
 appendChildren(buffer, node.getChildNodes());
...btw: IMHO the use of this forum is to get an answer to an particular question - not to ask for complete solutions - create the solution yourself an ask if you are stuck somewhere (with a bit of research (google) it is not hard to find a solution for your problem)

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 to Java object... please help really stuck

Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
 id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
 <family> Yoshi </family>
 <given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, Yo

Hi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

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;

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.

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 parse xml string using JSTL

Suppose this is my string:-----
<books>
<book>
<title id=1>Book Title A</title>
<author>A. B. C.</author>
<price>17.95</price>
</book>
<book>
<title id=2>Book Title B</title>
<author>X. Y. Z.</author>
<price>24.99</price>
</book>
</books>
and I want to read title id = 1 then, how to parse it, I found tutorials regarding parsing simple xml document but how to parse attributes of a given XML

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 a delimited string and insert into different columns?

Hi Experts,
I need to parse a delimited string ':level1_value:level2_value:level3_value:...' to 'level1_value', 'level2_value', etc., and insert them into different columns of one table as one row:
Table_Level (Level1, Level2, Level3, ...)
I know I can use substr and instr to get level value one by one and insert into Table, but I'm wondering if there's better ways to do it?
Thanks!

However, there is one tiny problem - the delimiter from the source system is a '|' When I replace your test query with | as delimiter instead of the : it fails. Interestingly, if I use ; it works. See below:
with t as (

select '|str2|str3|str4|str5|str6' from dual union all
select 'str1|str2|str3|str4|str5|' from dual union all
select 'str1|str2|||str5|str6' from dual)
select x,
regexp_replace(x,'^([^|]*).*$','\1') y1,
regexp_replace(x,'^[^|]*|([^|]*).*$','\1') y2,
regexp_replace(x,'^([^|]*|){2}([^|]*).*$','\2') y3,
regexp_replace(x,'^([^|]*|){3}([^|]*).*$','\2') y4,
regexp_replace(x,'^([^|]*|){4}([^|]*).*$','\2') y5,
regexp_replace(x,'^([^|]*|){5}([^|]*).*$','\2') y6
from t;
The "bar" or "pipe" symbol is a special character, also called a metacharacter.
If you want to use it as a literal in a regular expression, you will need to escape it with a backslash character (\).
Here's the solution -

2    select 'str1|str2|str3||str5|str6' x from dual union all

PS - it works for semi-colon character ";" because it is not a metacharacter. So its literal value is considered by the regex engine for matching.

Xerces - Parse XML from String

I am trying to parse an xml string using Xerces.
I have the following code:
String xml = <segments meters="8643" seconds="538" distance="5.4 mi" time="8 mins"><segment id="seg0" pointIndex="0" meters="122" seconds="11" distance="0.1 mi" time="11 secs">Head southwest from B Ave NE
