Use sys.property in xpath filter

[bhusted]

Is it possible to refer to a Java System property in a camel:xpath filter?

For example:

<camel:filter>
   <camel:xpath>/myns:SomeTag = ${sys.SomeSystemProp}</camel:xpath>
</camel:filter>


Any suggestions if this isn't possible for combining xpath and expression language would be REALLY helpful.

Thanks

Hi

See this wiki page
http://camel.apache.org/xpath

that may help a bit.

I reviewed that page extensively and found a reference to using the namespace

http://camel.apache.org/xml/variables/system-properties

What I am really looking for is an example that shows if it is possible to use a variable in the Xpath expression.

So in Java I do the following:  System.setProperty("MY_PROP", "MY_VALUE");

Then I define the system-property namespace and give it a prefix of "sys".  

What would the resulting Xpath expression look like?  Below are the examples I tried with no luck.

<camel:filter>
   <camel:xpath>/myns:SomeTag = ${sys.MY_PROP}</camel:xpath>
</camel:filter>

AND

<camel:filter>
   <camel:xpath>/myns:SomeTag = sys:MY_PROP</camel:xpath>
</camel:filter>

Hi

Do you mind putting together a small camel route that tries to filter
using xpath with that system property.
And provide a XML document that passed and one that does not.

Then we can use that for unit test to see if there is a gap in Camel.

Create a ticket in JIRA about this and attach the files there.
