XpathExtract - using an extracted value

[Bob C]

I am not sure how to access an extracted property in a later stage of the pipeline. The extract seems to be working, but when I try to use an extracted value in a later stage, an exception is thrown. Here is a snippet of my stage instance xml (a transform stage) :
<option>
<option-name>transformationFile</option-name>
<option-value>data/$document.get("carrier")</option-value>
</option>

Is it as simple as using document.get, or is there a little more setup involved.

Thanks,
Bob

Hello,

if you have something like
        <stage-inst>
            <stage-name>extract</stage-name>
            <stage-desc>this extracts stuff from the xml document</stage-desc>
            <stage-type>XpathExtract</stage-type>
            <option>
                <option-name>XPath</option-name>
                <option-value></option-value>

                <sub-option>
                    <option-name>id</option-name>
                    <option-value>/data/id/text()</option-value>
                </sub-option>

then, in a later stage, you could access the value as ${document.get("id")}
