Extract a value from a property in camel-context.xml

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?

To access the REQUEST property using simple you can do this:

${property.REQUEST}

To access properties using xpath:

<camel:xpath>
    function:properties("REQUEST")/[add your xpath expression here]
</camel:xpath>

More info on the properties function can be found here - https://camel.apache.org/xpath.html

I don't know if it's possible using properties, but you should be able to do it with headers.

Firstly:

<setHeader headerName="REQUEST">
    <xpath>/node()</xpath>
</setHeader>

Then if you wanted to set another header with just the author value:

<setHeader headerName="REQUEST2">
    <xpath headerName="REQUEST" resultType="java.lang.String">/book/@author</xpath>
</setHeader>

Or if you wanted to evaluate the value as a <choice> condition:

<when>
    <xpath headerName="REQUEST">/book/@author = 'ABC'</xpath>
