Parsing an xml document using XPATH

Hello,
I am pretty new to programming "Java and XML" and right now very confused with the range of available xml parsers,xpath engines and xslt processors.I need some guidance on how to parse a xpath expression with variables in it .
Thanks,
Chan.

Gregory . Thank you so much for the insight into parsing and xpath expression evalaution . I downloaded the XpathExamples.java file , practical xml jar file and executed the program to see the output for various example functions that you have created .All of them worked perfectly without any issues.
In the variablesExample() function , I added the following lines to check if it works :
variables.put(new QName("myvar"), "foo");
System.out.println("myvar bound as 'argle' = " + xpath.evaluate("/$foo/bar/baz", dom));
I ran into exceptions like ..
Exception in thread "main" javax.xml.transform.TransformerException: Extra illegal tokens: '$', 'foo', '/', 'bar', '/', 'baz'
Can you please tell me what was I doing wrong ? I am also planning to use starts-with() function in xpath expression . Will it work ?
Thank you for your reasoning.

Parse xml document with xpath

I would like to parse an xml document using xpath, see:
http://www.onjava.com/pub/a/onjava/2005/01/12/xpath.html
however, in the documentation (in the link above), it states that I need J2SE 5.0.
Currently, I have:
$ java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)
Does that mean that I really have to install J2SE 5.0 in order to use J2SE 5.0's XPath support? Does anybody know anything about getting started with XPath, and whether I can just use my existing version of Java? I've never used XPath.
For more documentation, one can view:
http://www.w3.org/TR/xpath20/
Thank you.

I have copied the code for the xpath tutorial on
http://www.onjava.com/pub/a/onjava/2005/01/12/xpath.html
exactly as it is on the tutorial, and imported the correct jars (I think).
But still my code is giving lots of errors!

Parsing an xml document inside a Thread

Hi Friends
I have to do some processing in my application for which i need to use multithreading.
Inside every new thread created i have to parse an xml document using s parsing tool like castor or jibx.
My question is that is it possible to parse a xml document inside a new thread everytime it gets created.
is it a good coding practice as it involves java code to do it.
Thanks
Vikeng

Hi
Thanks for the reply.
Well i need to do some kind of a batch processing in my application.
I need to parse an xml document and upload the data i get after parsing into columns in the database.
Since its a batch what i was asking was is it possible to do it for every request as batch needs to handle hundreds of records during the daily or nightly sync.
Is it a good practice to do parsing for every record in a batch
Thanks
VikengI don't get it. One batch is one document, and that document contains e.g. 100 records? What's one request? A request for one batch? I would execute one batch in one thread.

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.

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,

Unable to display tree view; Error when parsing an XML document (Premature end of file.)

Hi folks,
I am using a cascaded mapping in my OM. I have a graphical mapping followed by the Java mapping. It is a flat file to IDOC mapping. Everything works fine in Dev but when I transport the same objects to QA, the Operation mapping though it doesn't fail in ESR testing tool, gives the following message and there is no output generated for the same payload which is successfully tested in DEV. Please advise on what could be the possible reasons.
Unable to display tree view; Error when parsing an XML document (Premature end of file.)

kalyan,
There seems to be an invalid xml payload which causes this error in ESR not generating the tree view. Please find the similar error screenshot and rectify the payload.

SSMS 2012:FOR XML PATH Using XPath Node Tests-Columnn name 'test()' contains an invalid XML identifier as required by FOR XML?

I feel this xml output is not like the regular xml output. Do you know why it is diffrent from the regular xml xml output? Please comment on this matter.
Thanks,
Scott Chang
What do you mean by regular xml document? Are you referring to fact that its missing a root element? if yes it can be added as below
USE AdventureWorks;
GO
SELECT
p.NameStyle AS "processing-instruction(nameStyle)",
p.BusinessEntityID AS "Person/@ID",
p.ModifiedDate AS "comment()",
pp.PhoneNumber AS "text()",
FirstName AS "Person/Name/First",
MiddleName AS "Person/Name/Middle",
LastName AS "Person/Name/Last",
EmailAddress AS "Person/Email"
FROM Person.Person p
INNER JOIN Person.EmailAddress e
ON p.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.PersonPhone pp
ON p.BusinessEntityID = pp.BusinessEntityID
FOR XML PATH('ElementName'),ROOT('RootName');
replace ElementName and RootName with whatever name you need to set for element as well as the root element

How to parse multiple xml documents from single buffer

Hello,
I am trying to use jaxb 2.0 to parse a buffer which contains multiple xml documents. However, it seems that it is meant to only parse a single document at a time and throws an exception when it gets to the 2nd document.
Is there a way I can tell jaxb to only parse the first complete document and not fetch the next one out of the buffer? Or what is the most efficient way to separate the buffer into two documents without parsing it manually. If I have to search the buffer for the next document root and then split the buffer, it seems like that defeats the purpose of using jaxb as the parser.
I am using the Unmarshaller.unmarshall method and the exception I am getting is:
org.xml.sax.SAXParseException: Illegal character at end of document, <.]
 at javax.xml.bind.helpers.AbstractUnmarshallerImpl.createUnmarshalException(AbstractUnmarshallerImpl.java:315)
 at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.createUnmarshalException(UnmarshallerImpl.java:476)
 at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal0(UnmarshallerImpl.java:198)

 at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:137)
 at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:184)
Thank you for your help

It's just like any other XML parser, it's only designed to parse one XML document. If you have something that concatenates two XML documents together (that's what your "buffer" sounds like), then stop doing that.

Validation of an XML document using an XMLSchema !

Hi all,
i have an xml document and an XmlSchema.
Well, my mission is validate the xml document using the XmlSchema and give the message true or false to the user.
What is the best,easier and faster way to do this ?
Cheers.
Stefano

I would like to do the same thing only I would like to use JAXP. The JAXP 1.2 samples show the following code to accomplish this:
final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
final String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
//create and configure SAX parser factory
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
spf.setValidating(true);
//create and configure SAX parser
SAXParser saxParser = spf.newSAXParser();
saxParser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
saxParser.setProperty(JAXP_SCHEMA_SOURCE, new File(schemaSource));
//parse XML document
saxParser.parse(new InputSource(xmlURI), myDefaultHandler);
However, I would like to use the default Crimson parse that ships with J2SE 1.4. Is there a way to accomplish this using the default Crimson parser that only support JAXP 1.1?

Create xml document by xpath in java

as i know, i can navigate existing xml document by xpath in java, i wonder if i can create a xml document framework by xpath in java?
something like:
Document doc = someobject.create(xpath expression);
then i can use DOM to fill the framework?
Thanks

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!!

Hi Rodrigo,
Do you use a specific "encoding" like UTF-8 or ISO-8859-1 in your Sender CC.
Try changing the Transfer mode to Binary instead of Text.
Also go through these links:-

Invalid char in XML from inbound IDoc
Hope this provides a solution.

How do I parse a XML document?

Hello
I have a problem parsing a XML-document like the one below: Can anyone help me with a code example or something to get the tag "<Name>" out so that I get the string "Example5" and "Example3" out.
Thnx for any help!
Jimmy
The XML file looks like this (but without the line in the beginning of each row):
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE ThisExample SYSTEM "C:/example.dtd">
<?xml-stylesheet type="text/xsl" href="first.xslt"?>
<ThisExample>
____<Product>
________<Product_number>no1</Product_number>
________<Number>number1</Number>
____</Product>
____<Product>
________<Product_number>no2</Product_number>
________<Number>number2</Number>
____</Product>
____<Group>
________<Type>EX1</Type>
________<ProductVersionAllowed>Y</ProductVersionAllowed>
________<Preprocess>precmd.csh</Preprocess>
________<Postprocess>echo Finished</Postprocess>
________<Document>
____________<Name>Example1</Name>
____________<Product_number>no1</Product_number>
____________<Ticked_by_default>Y</Ticked_by_default>
________</Document>
________<Document>
____________<Name>Example2</Name>
____________<Product_number>no1</Product_number>
____________<Ticked_by_default>Y</Ticked_by_default>
________</Document>
________<Document>
____________<Name>Example3</Name>
____________<Product_number>no1</Product_number>
____________<Ticked_by_default>Y</Ticked_by_default>
________</Document>
____</Group>
____<Group>
________<Type>EX2</Type>
________<ProductVersionAllowed>N</ProductVersionAllowed>
________<Preprocess>precmd.csh</Preprocess>
________<Postprocess>echo Finished</Postprocess>
________<Document>
____________<Name>Example4</Name>
____________<Product_number>no2</Product_number>
____________<Ticked_by_default>Y</Ticked_by_default>
________</Document>
________<Document>
____________<Name>Example5</Name>
____________<Product_number>no2</Product_number>
____________<Ticked_by_default>Y</Ticked_by_default>
________</Document>
____</Group>
</ThisExample>

Thnx :O)
Now it worx!
Just one more thing. Can I get the number of elements there is in a tag? I.e. how many "Document"'s there are in 1 "Group"? I need this because I have too loop through a "Group" and print the name of every "Document".
At the moment I'm doing it like below, but that is not a nice solution, and it realy does not work that well:
Jimmy
int i = 1;
do
node = org.apache.xpath.XPathAPI.selectSingleNode(doc, "/PosttoolControl/Group[position()=" + i + "]/Type");
if (node.getFirstChild().getNodeValue() != null)
type = node.getFirstChild().getNodeValue();
PostToolDocGroupeComboBox.addItem(type);
i++;
} while (node.getFirstChild().getNodeValue() != null);

Poweshell script to parse a XML document to get all Leaf level nodes with Node names in CSV

Hi Experts,
I want to write a Powershell script to parse a XML document to get all Leaf level nodes with Node names in CSV
<?xml version="1.0" encoding="UTF-8"?>
<CATALOG>
 <CD>
 <TITLE>Empire Burlesque</TITLE>
 <ARTIST>Bob Dylan</ARTIST>
 <COUNTRY>USA</COUNTRY>
 <COMPANY>Columbia</COMPANY>
 <PRICE>10.90</PRICE>
 <YEAR>1985</YEAR>
 </CD>
</CATALOG>
Need to display this as
CD_Tiltle, CD_ARTIST, CD_COUNTRY, CD_COMPANY, CD_PRICE, CD_YEAR
Empire Burlesque, Bob Dylan,USA,Columbia,10.90,1985
and so on..
I do not want to hard code the tag names in the script.
current example is 2 level hierarchy XML can be many level till 10 max I assume
in that case the csv file field name will be like P1_P2_P3_NodeName as so on..
Thanks in advance
Prajesh

Thankfully, I have writtenscript for ths same $node_name="";
$node_value="";
$reader = [system.Xml.XmlReader]::Create($xmlfile)
while ($reader.Read())
while ($reader.Read())
if ($reader.IsStartElement())
$node_name += "," + $reader.Name.ToString();
if ($reader.Read())
$node_value += "," + $reader.Value.Trim();
Thanks and Regards, Prajesh Please use Marked as Answer if my post solved your problem and use Vote As Helpful if a post was useful.

Error while loading an XML document using a structured application

Hi,
I try to load an XML document using a structured application defined in the default structapps.fm
My code is shown down, extracted from the FDK API code sample.
Problem, I always have the same message :
"Cannot find the file named e:\xml\AdobeFrameMaker10\file. Make sure that the file exists. "
Where "e:\xml\AdobeFrameMaker10\" is my install directory.
So I assume that frame try to find the structapps.fm file but does not find it.
What else can it be ?
Does anyone knowns how to achieve this simple task using extendScript ?
Thanks for any comments, Pierre
function openXMLFile(myLastFile) {
    var filename = myLastFile.openDlg("Choose XML file ...", "*.xml", false);
    if (filename != null) {
        /* Get default open properties. Return if it can’t be allocated. */
        var params = GetOpenDefaultParams();
        /* Set properties to open an XML document*/
        /*Specify XML as file type to open*/
        var i = GetPropIndex(params, Constants.FS_OpenAsType)
        params[i].propVal.ival = Constants.FV_TYPE_XML;
        /* Specify the XML application to be used when opening the document.*/
        i = GetPropIndex(params, Constants.FS_StructuredOpenApplication)
        params[i].propVal.sval = "myApp";
        i = GetPropIndex(params, Constants.FS_FileIsOldVersion)
        params[i].propVal.ival = Constants.FV_DoOK
        i = GetPropIndex(params, Constants.FS_FontNotFoundInDoc)
        params[i].propVal.ival = Constants.FV_DoOK
        i = GetPropIndex(params, Constants.FS_FileIsInUse)
        params[i].propVal.ival = Constants.FV_DoCancel
        i = GetPropIndex(params, Constants.FS_AlertUserAboutFailure)
        params[i].propVal.ival = Constants.FV_DoCancel
        /*The structapps.fm file containing the specified application must have
        already been read. The default structapps.fm file is read when FrameMaker is
        opened so this shouldn't be a problem if the application to be used is
        listed in the structapps.fm file.*/
        var retParm = new PropVals()
        var fileObj = Open(filename, params, retParm);
        return fileObj
    } else {
        return null;

Pierre,
Depending on the object "myLastFile", the method openDlg might not even exist (if the myLastFile object is not a File object, for instance). And I do not see any need for the myLastFile anyhow, as you are presenting a dialog to select a file to open. I recommend using the global ChooseFile( ) method instead. This will give you a filename as string in full path notation, or null when no file was selected in the dialog. I am not sure what your ExtendScript documentation states about the return value for ChooseFile, but if that differs from what I am telling you here, the documentation is wrong. So, if you replace the first lines of your code with the following it should work:
function openXMLFile ( ) {
    var filename = ChooseFile ( "Choose XML file ...", "", "*.xml", Constants.FV_ChooseSelect );
While writing this, I see that Russ has already given you the same advice. Use the symbolic constant value I indicated to use the ChooseFile dialog to select a single file (it can also be used to select a directory or open a file - but you want to control the opening process yourself). Note that this method allows you to set a start directory for the dialog (second parameter). The ESTK autocompletion also gives you a fifth parameter "helplink" which is undocumented and can safely be ignored.
Good luck
Jang
