RE: [xsl] A more complicated Muenchian Method exercise

["Greg Johnson" <gjohnson@xxxxxxxxxxxx>]

There is a slight weakness to this approach: I am unable to do an alphabetic
sort of the entire set, because although I may be able to build the key on
the entire "Trading Partner" set, I am subsequently forced to test for
membership in that set in two steps:

<!-- Sender -->
<xsl:for-each select="DTSEnvelopes[count(. |
key('DTSEnvelopes-by-arrived-tp',concat(substring-before(arrived, 'T'), ' ',
Sender/tpid) )[1]) = 1]" >...</xsl:for-each>

and then

<!-- Recipient -->
<xsl:for-each select="DTSEnvelopes[count(. |
key('DTSEnvelopes-by-arrived-tp',concat(substring-before(arrived, 'T'), ' ',
Sender/Recipient/tpid) )[1]) = 1]" >...</xsl:for-each>

because the Method uses the concat() function to test membership as well as
building the key.  How do I combine the above into one looping block?

Any suggestions?

  but the conversion of the OR'd set to a string does not work.  It seems to
  ignore the rec_id, and I only get the sender set.


Yes, it is a general feature of Xpath1 string functions, that if you
give them a node set and theey want a string, they take teh firat node
of the node set and take its string value, and junk everything else.

I think you just want two xsl:key statements:

<xsl:key name="key2_name", match="header" use="concat(arrive_date, ' ',
sender/sen_id )"/>
<xsl:key name="key2_name", match="header" use="concat(arrive_date, '
',sender/recipient/rec_id )"/>


multiple xsl:key statements with the same name form a combined key.
