Parsing a XML in DSL

["anish.somadevan" <ne...@gmail.com>]

Am trying to parse the input XML of a route to get a particular node's value.
I tried this way,

<xpath>/CamelData/Provider/text()</xpath>

But this throws an error,

java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault
cannot be cast to org.apache.xml.dtm.DTMManager:
java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault

	at
org.apache.camel.builder.xml.XPathBuilder.doInEvaluateAs(XPathBuilder.java:860)
[camel-core-2.10.3.jar:2.10.3]

Is there a way to get this resolved, or a better approach to parse the XML
in DSL?

Thanks,
Anish

You should use Saxon for many reasons...

I suggest adding the camel-saxon dependency and use:
<xpath saxon="true">/CamelData/Provider/text()</xpath>

Best,

<convertBodyTo type="String"/>
<xpath>/CamelData/Provider/text()</xpath>

Looks like your message is not in the expected format. Add a convertBodyTo
String before xpath. It should work.
