Document Function Befuddlement
I'm working on an application where I have to periodically run a number of xml
files that I'm given through the same xsl transform.
Conveniently, I also get another xml file that lists the names of all of the
data files, so this seemed like the perfect chance to
put the document function to good use (my first time).
I'm on a PC running XP SP2, using IE 7 & xsl 1.0. Below I've included a much
reduced test process that I've been using to get it
working - it simply lists the position, name and value of all element nodes.
'day1.xml' & 'day2.xml' are the data files, 'monthly list.xml' is the list of
file names and I use 'list nodes.xml' to trigger the
whole thing by loading it into IE.
My befuddlement comes in because I'm getting more output from a more
restrictive selection criteria than I am from a less
restrictive selection criteria.
If, in 'monthly process.xsl', I use
<xsl:for-each select="document($monthly_link/@link)/daily//*">
I get, correctly:
Pos Name Value
--- ---- -----
1 client
2 day 1
3 name John
4 client
5 day 2
6 name Margaret
However, this doesn't show the daily nodes, which I wanted included also, so I
tried:
<xsl:for-each select="document($monthly_link/@link)//*">
I get, unexpectedly:
Pos Name Value
--- ---- -----
1 daily
2 client
3 day 1
4 name John
What I expected (and wanted) from the use of //* is:
Pos Name Value
--- ---- -----
1 daily
2 client
3 day 1
4 name John
5 daily
6 client
7 day 2
8 name Margaret
Would someone please explain why this is happening and what I should do to get
the results I need?
Thanks in advance
