Hi
See this page
http://camel.apache.org/xpath
About namespace auditing. If your xml has namespaces, then your xpath
expression must have that as well.
And then its not so easy to get working.
There may be some xpath tools / tutorials you can take a look at to make the
count work
Maybe something like
"count(//h3)"
Mind that if you have namesapces, you need to add that to the count
"count(//foo:h3)"
Where foo is your namespace "key".
