Extract the value from property
The input looks like below,
<book author="ABC" type="Children">
<id>123</id>
<name>XYZ</name>
</book>
I have set the above in property in an xml route as:
<camel:setProperty propertyName="REQUEST">
<camel:xpath>/node()</camel:xpath>
</camel:setProperty>
Then I do some other processing and based on the new response. I want to
extract the value of an author(i.e. ABC) from this Property and compare it
with a element's text string from the response.
I tried a few ways using camel:xpath and camel:simple but am not able to
extract the value from property.
What is the correct way to extract this property?

Just replace "setHeader" with "setProperty" ...

Thanks for replying, but I know how it is done with header. I want the
solution using property.

Haven't tried SpringDSL, but this works for me.
