Re: [xsl] shortest way to write this xsl:if statement

[henry human <henry_human@xxxxxxxx>]

Now the problem is, the loop bellow of xsl:if is only one time created but I
have more findings in the if statement 
regarding A, B, C, D (founds at least
4 times because D4/G100/6id = 'A' , D4/G100/9id = 'B' , D4/G100/10id = 'C' ,
D4/G100/11id ='D')
=> the code bellow of the xsl:if statemnt should be
repeated as much as if statement find A, B, C, D,..

Element names cannot begin with digits, so I'm unclear how you are
going to be testing elements such as <6id>.

But, assuming you had elements
D4/G100/X and D4/G100/Y and D4/G100/Z, you could have in XSLT2 the following:
<xsl:if test="D4/G100/(X,Y,Z) = ('A','B','C')">

... which is equivalent to:
  D4/G100/X = 'A' or
  D4/G100/X = 'B' or
  D4/G100/X = 'C' or
  D4/G100/Y =
'A' or
  D4/G100/Y = 'B' or
  D4/G100/Y = 'C' or
  D4/G100/Z = 'A' or
 
D4/G100/Z = 'B' or
  D4/G100/Z = 'C'

When using the "=" comparison operator,
either operand can be a set.  The processor walks through the comparisons in
an arbitrary order eventually testing each of the left operand with each of
the right operand and stops when it hits a true() result and returns true(). 
If you get a false() returned, you know the processor has checked every
possible combination and every combination has returned false().

I hope this
helps.
