David KarrSubject: Map element to element, but only for instance with a particular attribute value?
Author: David Karr

I'm finding I know what I need to do in xslt, but I'm having trouble
visualizing how to do it graphically in the mapper. I'll try to
describe what I have so far.

I have a source and target schema, and I've set the source and target
context on each side.

In my source schema, I have an element "AdditionalOutputData" that has a
sequence of "DataAttribute" elements, which have a "name" attribute. I
know that in my source document, one of the "DataAttribute" elements
will have a "name" value of "id". I need to copy the "DataAttribute"
body in that case to the "UID" element in my target schema.

I figured the XSLT for this might look something like this:


xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:a="..."
xmlns:b="...">


select="b:AdditionalOutputData/b:DataAttribute[@name='id']"/>




It's the condition part that's stumping me. I don't see how I would
best represent this in the mapper canvas, so the logic is represented
graphically (as much as possible).

David,
Can you attach the two schemas?
Thanks much,

Ok. I was assuming this could be answered with a general strategy, but
I'll attach them.

David,

As you suggested, you need to create this value-of:

<xsl:value-of select="AdditionalOutputData/DataAttribute[@name='id']"/>

Mapper has no graphical representation for predicates, so you need to first create the simple value-of

<xsl:value-of select="AdditionalOutputData/DataAttribute"/>

graphically, then edit the XSLT code in the source pane, adding the [@name='id'] attribute.
