Hi Mike,
I was trying to solve this problem the XSLT 1.0 way,
but am facing some problem. I am using Saxon 6.5.3.
The XML file I used is -
<?xml version="1.0" encoding="UTF-8"?>
<root>
<statement-message>Your account is now seriously in
arrears.
To</statement-message>
<statement-message>avoid further action a payment
of</statement-message>
<statement-message>$82.00 is required immediately.
Any</statement-message>
<statement-message>purchases will now be
declined.</statement-message>
<statement-message>
</statement-message>
<statement-message> More text </statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
</root>
The XSLT file I used was -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes" />
<xsl:template match="/root">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="node() | @*" />
</xsl:copy>
</xsl:template>
<xsl:template match="statement-message" />
</xsl:stylesheet>
This is a usual modified identity stylesheet..
But I am getting output -
<?xml version="1.0" encoding="utf-8"?>
Press any key to continue . . .
Can you please tell, is there problem somewhere?
Regards,
Mukul

When you do xsl:value-of select="." directly inside
xsl:for-each-group, "."
refers to the first item in the group. You want to
output the concatenation
of all the items in the group, which you can do with
string-join(current-group(), ' ')
Also, each empty element that's followed by another
empty element is being
treated as a group containing a single member.
I think I would tackle this using
group-adjacent="string-length(.)=0"
This will create a sequence of groups, alternating a
sequence of empty
elements with a sequence of non-empty elements. You
can then test if the
first element in the current group is non-empty, and
if so, output the
string-join as above.

Subject: [xsl] Group problem with blank elements
Hiya,
Having loads of trouble with this. On the face of
it a really easy
problem.
I have a bunch of elements like so:
<statement-message>Your account is now seriously
in arrears.
To</statement-message>
<statement-message>avoid further action a payment
of</statement-message>
<statement-message>$82.00 is required immediately.
Any</statement-message>
<statement-message>purchases will now be
declined.</statement-message>
<statement-message>
</statement-message>
<statement-message> More text
</statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
I want to strip out the empty tags and merge
adjacent elements as
follows:
<statement-message> Your account is now seriously
in arrears. To avoid
further action a payment of
82.00 is required immediately. Any purchases will
now be
declined.</statement-message>
<statement-message> More text
</statement-message>
My code at the moment is:
<xsl:for-each-group select="statement-message"
group-ending-with="statement-message[string-length(normalize-s
pace(follo
wing-sibling::statement-message[1]))=0]">
<statement-message>
<xsl:value-of select="."/>
</statement-message>
</xsl:for-each-group>
My understanding of this is that it should start
grouping from the 1st
statement message, with the groups ending as soon
as an empty
element is
reached. The empty tags at the end would still be
there, but at least
it should do the merge. However, the result looks
like:
<statement-message>Your account is now
seriously in arrears.
To</statement-message>
<statement-message>
</statement-message>
<statement-message> More text
</statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
<statement-message>
</statement-message>
So where am I going wrong?
Ed
