Hi,

Can anyone lead me to examples of using xpath functions in filters. I am working on Mule 3.1

For example: If I use the xpath filter with the function 'exists', or even the jaxen filter I get the error below.

The idea is to check for the existence of the <error> element in the response.

<mule-xml:xpath-filter pattern="exists('//sam:NewOperationResponse/error')"/>

Just a shot in the dark: did you endorse your JDK as described in the
"Installing Required Software" -> "Java" section?

Hi Dirk,

I had missed that step. So I copied the endorsed directory available in the mule distribution (mule-standalone-3.1.0\lib\endorsed) into jre\lib.

But the issue persists.

Mule 3.1 is running within Mule IDE(Eclipse Helios).
JDK: 1.6.0_21-b07

Hi,

Has anyone been able to use xpath functions within filter expressions. Kindly let me know. I have copied the endorsed dir available under mule-standalone-3.1.0\lib to jre\lib. It doesn't work for me. May be I am still missing something. It works within the XSLT tranformer but not in the filter expression.

Here is my config.

Hi,

Instead of the "exists" function I used the "boolean" function to identify the existence of an element in the source XML.

Here are my findings on using xpath functions in filters,

When using jaxen-filter, we need to prefix function with the default xpath function namespace alias *fn:* But while using the xpath-filter we don't need to use this function namespace prefix.

Note: Jaxen supports only few of the xpath functions. For the supported functions have a look at the below api link.
