Bit of a newbie here. I want do some quite simple file processing. I have a
basic source file with file references in it. These files should be merged
into a variable, which can then be further processed; in my example below the
@amount of each line[(_at_)ref] is summed. But I'm already stuck in the first
part of this, how do I correctly put file1.xml and file2.xml into a variable
which then contains (psuedo)
"<root><data><lines/></data>><data><lines/></data></root>"? And how can I
then use that variable as a basis for further processing?
I'm using XSLT 1.0.
<!-- To XML to process -->
<?xml version="1.0"?>
<files>
<file href="file1.xml"/>
<file href="file2.xml"/>
</files >
<!-- file1.xml -->
<data>
<line ref="A" amount="2"/>
<line ref="B" amount="3"/>
</data>
<!-- file2.xml -->
<data>
<line ref="A" amount="4"/>
<line ref="B" amount="8"/>
</data>
<!-- result should be -->
<data>
<line ref="A" amount="6"/>
<line ref="B" amount="11"/>
</data>
