Hi All,
B
Thank youB to all your valuable suggestions but I am still not
completely clear on how to apply document() function to query node-set from
secondary documents using XPath just yet, even though the concept is simple
enough. Let's look at an example found on
http://www.ibm.com/developerworks/xml/library/x-tipcombxslt/ with the
following documents:
cListing 1. geneva.xml -- an XML description of a photo
<?xml version="1.0"?>
<ph:photo xmlns:ph="http://ananas.org/2003/tips/photo">
B <ph:title>The Jet d'Eau fountain</ph:title>
B
<ph:location>Geneva</ph:location>
B <ph:date>April 2003</ph:date>
B
<ph:description>
B B B The Jet d'Eau fountain is the most recognizable symbol
of Geneva.
B B B The fountain reaches 140 meters (460 feet) high, roughly the
same height
B B B as the Embassy Suites hotel in Times Square.

</ph:description>
</ph:photo>
Listing 2. london.xml -- another XML
description of a photo
<?xml version="1.0"?>
<ph:photo
xmlns:ph="http://ananas.org/2003/tips/photo">
B <ph:title>Double-decker
bus</ph:title>
B <ph:location>London</ph:location>
B <ph:date>October
2002</ph:date>
B <ph:description>
B B B An inescapable symbol of London, the
double-decker bus is much taller
B B B than typical buses to carry many
passengers through the city'sB B
B B B overcrowdedB streets.
B
</ph:description>
</ph:photo>
Listing 3. index.xml lists the secondary
sources
<?xml version="1.0"?>
<ph:index
xmlns:ph="http://ananas.org/2003/tips/photo">
B <ph:title>City
sights</ph:title>
B B <ph:entry>geneva</ph:entry>
B
<ph:entry>london</ph:entry>
B <ph:entry>paris</ph:entry>
B
<ph:entry>roma</ph:entry>
</ph:index> c
Listing 4. merge.xsl -- the
stylesheet processes the documents listed in the main source
1<?xml
version="1.0"?>
2<xsl:stylesheet version="1.0"

I
would like the following clarification on the merge.xsl:
B
( i ) Is it true
that lines 8 - 13 retrieves content of /ph:index/ph:title? If so what is the
purpose of lines 15 - 17?
( ii ) What does line 21 do especially the concat()
function and which document is it reading from? Is it index.xml? Does it mean
that lines 8 - 23 all uses the same document as a result from this line?
Likewise, where in this stylesheet that references the secondary source
index.xml?
( iii ) Lines 25 - 39 appears to retrieve content of various nodes
in the primary source (either geneva.xml orlondon.xml). Exactly which one of
them is the primary source document? Or is it able to lookup both at the same
time?
( iv ) Lines 25 - 39 all uses
( v ) Lastly, is URI in XSLT is
equivalent to filename? e.g. document('geneva.xml')
B
Again, this area is
very new area to me so your patient would be much appreciated.
B
Thanks,
Jack
B <xsl:apply-templates/>. Does this statement navigates to the node-set
matched within the template only? Or does it also returns the content as well?
I thought that only <xsl:value-of select="..."/> could accept the target value
being queried.

perhaps here should be xsl:value-of??
