Using jaxen to parse xpath expressions
Hi,
I want to parse this XPath expression with jaxen: +$X//employee[@id=0529]/salary+
after parsing i got this: +$X/descendant-or-self::node()/child::employee[(attribute::id = 529.0)]/child::salary+
Jaxen doesn't parse +//employee+ as I expected.
Is descendant-or-self::node()/child::employee equivalent to descendant-or-self::employee ?

If I had to choose whether I think Jaxen interprets the XPath specs correctly or whether you do, I would choose Jaxen. But if you don't think so, wouldn't it be better to ask questions about Jaxen on the Jaxen mailing list?

Is there a Java API that parses XPath expressions and produces the resultant XPath tree in memory?
For example the xpath expression: /a/b[c/d]/e/f
will produce a tree with "a" as the root node, "b" as a sub-node, "c" and "e" as subnodes of "b" and so on.
I don't want one that is to be evaluate against and XML document. I just want the XPath Expression tree to be build in memory.
Thankshi,
look at javacc, a compiler very popular, with many examples.

Using substring in the XPATH expression for Receiver Determination
Hello, I need a little help please. In my receiver determination, I have a condition and I need to do a "not like" check. Basically, if the first three positions of the source field does not start with a specific code, then I need to execute the condition. The condition editor does not support a "not like" operand, so I went to the XPATH expression editor. I tried to used the XPATH substring function to get the first three characters and then do a "not equal" operand, but it doesn't appear to work. There are not any runtime errors, but the condition is not executing. Any ideas on this? Does the XPATH expression support the substring function?
Hi Jesse,
Can you please explain what is the meaning of http:// in the statement
/p1:PRODUCT/MATNRhttp://not(substring(.,string-length(.) - 2) = '123')
Please explein, I am having same issue. It is not working here.In My case it is
/p1:ORDERS01/IDOC/E1EDP01/E1EDP19/IDTNR[http://not(starts-with(.,\"D\"))]
also tried with
/p1:ORDERS01/IDOC/E1EDP01/E1EDP19/IDTNR[http://not(starts-with(.,'D'))]
Thanks in advance! -
Evaluate XPath expression using SAXON/JAXP/JDOM
I have a somewhat unique requirement. Working on a legacy application with XML code / libraries littered all over the place. Trying to improve performance.
First requirement (to avoid massive refactoring):
Can I use Saxon to process Xpath Expressions using the JAXP apis (because this is what's used in the app currently) on JDOM documents?
I'm not familiar with saxon api enough....any help/code samples is appreciated.

Reuse a variable in OSB XPATH expression editor
I have a problem with replacing activity in Oracle Service Bus.
I created a variable with the follow content
<response>
<operationResponse name="OPERATION1" result=""/>
<operationResponse name="OPERATION2" result=""/>
<operationResponse name="OPERATION3" result=""/>
<operationResponse name="OPERATION4" result=""/>
</response>
For each operationResponse I call a businessProxy that invokes an external webservice. If this call is made with success, I replace `result=""` with `result="1"`.
I have created a replace activity like this:
<con3:replace contents-only="true" varName="responseElement"> <!-- var responseElement = <response>.*</response> -->
<con2:id>_ActionId-3886365367816551561--27a55993.13f0a38ab8f.-7c95</con2:id>
<con3:location>
<con2:xpathText>./operationResponse/@result</con2:xpathText>
</con3:location>
<con3:expr>
<con2:xqueryText>"1"</con2:xqueryText>
</con3:expr>
</con3:replace>
After running this program, all the attributes "results" are replaced by "1", if the businessService is called successfully.
The problems is that I need to replace the attribute "result" only for the element operationResponse that have the attribute "name" equal to the operationResponse that invokes the businessService.
I have created a variable called operationName that contains the current response/operationResponse. I used ./operationResponse[@name=$operationName]/@result.
The OSB XPATH expression editor is throwing the follow error:
Variable "$operationName" used but not declared for expression
Can anyone help with this?Hi, XPath and XQuery are conceptually different. XPath expression can not have variables while an XQuery expression can have a variable inside the XPath when the expression is bound to a variable.
To work around the issue, instead of using the condition in XPath expression inside replace you should write the XQuery expression of REplace in such a way that it results in what you need.
For ex. if I take the example above:
say the content of $body is as below:
<soap-env:Body>
<aaa>
<bbb>
<ccc>A</ccc>
<key>1</key>
</bbb>
<bbb>
<ccc>B</ccc>
<key>2</key>
</bbb>
</aaa>
</soap-env:Body>
and you wanted to replace values of ccc to X for any bbb elements which have key=1(and you have saved a variable called keyCheck with value '1' earlier in the flow), then you could do the following:
Replace contents of . in body with
<aaa>
for $bbb in $body/aaa/bbb
if ($bbb/key/text() = $keyCheck)
then
<bbb>
<ccc>X</ccc>
<key>{$bbb/key/text()}</key>
</bbb>
else
$bbb
</aaa> -

Now I have converted my solution to use a structured index. As such, I want to write the where clauses in terms of column names rather than XPath expressions.
I hoped it was as simple as changing the code that generates the XPath expression to generate a SQL expression. After making that change, I'm now getting this error:

Using xpath expressions in Document-Builder
Hi all
we have re-designed our (existing) DDX-templates with the Document Builder in LC Workbench. The DDX templates are used to assemble PDFs with LC Assembler-Service.
Now my question: Is it still possible to use XPath-expression in the DDX template? Please find our example below:
The XPath expression works only if we copy&paste the DDX source code directly to the Assembler-Service property view (picture below). But referring the DDX-template doens't interpret the xpath path at run time (2nd picture below). Any help on that will be appreciated!
Works (using DDX source code directly):

Using a xpath expression stored in a variable
Hi All,
I have an xpath expression which is stored in the database which I need to use against the request XML. I am able to retrieve this Xpath expression from the database, but not able to use it against the request XML.
Xpath expression got from the database is: /request/param//name.
I have tried $body/$XpathVariable, this does not work. I can not hard code this expression during my design time, so the details of the expression has to be fetched at run time.
Any ideas to get the value would helpful.

Selecting nodes using an XPath expression
Assuming that I have a DOM Document object containing a valid XML file, what is the quickest way to select a subset of nodes from the document using an XPath expression. I would like the results in either a NodeList object or another Document object.
Microsoft has a way to do this using a single method named 'selectNodes'. Why is querying an XML document so hard to do using java? Am I missing something?In case you're using Xalan take a look at org.apache.xpath.XPathAPI. The function selectNodeList(...) probably does what you want.
Good luck. -
