Re: [xsl] position() > 1 not working

["Michele R Combs mrrothen@xxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi David b

Ah.  Ok, so if I understand correctly, I need to change the variable
assignment to grab the position of the <DATA> element within the parent <ROW>,
rather than within the for-each?  How would I do that?

But then also, why didnbt the second option work, where I for-each all the
<DATA> elements and then test the position (<xsl:if test="position() > 1" />)?

Thanks

Michele

there are 4 DATA children so

<xsl:for-each select="fmp:COL[3]/fmp:DATA[position() > 1]">

selects the 2nd, 3rd and  4th

the scope of that position() is just that step of the xpath, within the body
of the for-each, position() counts the selected items
so as there are three items selected position() as stored in $parent-position
will have values 1,2,3 which is one less than you expected.

I want to select all the child <DATA> elements of a <COL> except for the first
one.  Ibve tried several different things but I must be missing something
stupidly obvious since it isnbt working.

Input data:

<ROW>
   <COL><DATA></DATA></COL>
   <COL><DATA>Adult Education Audio and Video Collection</DATA></COL>
   <COL>
      <DATA>SULF</DATA>
      <DATA>Bird</DATA>
      <DATA>Bird</DATA>
      <DATA>Hawkins</DATA>
   <COL>
   <COL>
      <DATA></DATA>
      <DATA>24:F:4</DATA>
      <DATA>36:G:5-7</DATA>
      <DATA>234:A:1-5</DATA>
   <COL>
   <COL>
      <DATA>Box 1-22</DATA>
      <DATA>Adds, 3 boxes</DATA>
      <DATA>Box 23-45</DATA>
      <DATA>Oversize items</DATA>
   <COL>
</ROW>


In my XSL:
<xsl:for-each select="fmp:COL[3]/fmp:DATA[position() > 1]">
  <xsl:variable name="parent-position" select="position()" />
  <xsl:value-of select="../../fmp:COL[3]/fmp:DATA[$parent-position]"/>
  <xsl:value-of select="../../fmp:COL[4]/fmp:DATA[$parent-position]"/>
  <xsl:value-of select="../../fmp:COL[5]/fmp:DATA[$parent-position]"/>
</xsl:for-each>

Expected output:
   Bird 24:F:4 Adds, 3 boxes
   Bird 36:G:5-7 Box 23-45
   Hawkins 234:A:1-5 Oversize items

Actual output:
   SULF Box 1-22
   Bird 24:F:4 Adds, 3 boxes
   Bird 36:G:5-7 Box 23-45
   Hawkins 234:A:1-5 Oversize items


I also tried just getting all the <DATA> elements and then testing the
position:

   <xsl:for-each select="fmp:COL[3]/fmp:DATA">
      <xsl:if test="position() > 1" />

But that gave the same results.  Just to be sure I wasnbt crazy, I added an
<xsl:value-of> statement to spit out the value of position() at each point,
and I see exactly what I expect there (1, 2, 3, 4).  What am I missing?
