I have the following problem.
Source structure:
<header>
<segment>
<value1>A</value1>
<value2>B</value2>
</segment>
<segment>
<value1>C</value1>
<value2>D</value2>
<segment/>
<segment>
<value1>E</value1>
<value2>F</value2>
<segment/>
</header>
If the field value1 concatenated with value2 is equal to CD somewhere in the source structure then I want to produce the following target.
<header> <indicator>X</indicator> </header>
If the source structure value fileds concatenated is equal to XY then the following target.
<header> <indicator>B</indicator> </header>
Otherwise the following target.
<header> <indicator/> </header>
How would I solve this with a gra
