I have input XML which transforms to an output XML. The transformation
works fine, but I need to fill in one field that is dependent on the
number of nodes in a section of the *output *document. Due to
confidentiality, I can't post the actual document. Here is what the
output looks like:
<doc>
<header>
...
</header>
<body>
<data>
<elem1/> <!-- actual names vary -->
<elem2/>
</data>
<summary dataCount="2"/>
</body>
</doc>
The number of elements within <data> is variable. I need to calculate
the dataCount attribute from the number of <data> elements. What is a
good solution for this? I'd rather not use a second transform step
unless absolutely necessary.
