Hallo Mr Kay,

Please excuse me for bothering you again, but i am close to presenting my
MSc dissertation project
and being under a lot of pressure, i find my self getting stuck with things
that i would
normally manage to confront with, under diferrent circumstances. My new
question and hope the last related
to the current project i am working relates to the code for comparing
numbers to node-sets
that you send me yesterday.

The source xml is the one following, slightly diferrent from the one i sent
you yesterday(it
just includes and a second SHAPE element).

<?xml version="1.0" encoding="ISO-8859-7"?>

                  </ORDINATES>
            </SHAPE>
      </ROW>
</ROWSET>


I am using the following stylesheet to select all ORDINATE_ITEM contents in
a string
as the content of a new polygon element of the output xml.



<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
      <xsl:output indent="yes"/>
      <xsl:template match="/">
      <PolygonSet>
      <xsl:for-each select="ROWSET/ROW">
      <polygon>
                  <xsl:for-each select="SHAPE/ORDINATES/ORDINATES_ITEM">
                        <xsl:choose>
                              <xsl:when test="position() mod 2 = 1">
                                    <xsl:value-of
select="format-number(.,'#')"/>
                                    <xsl:text>,</xsl:text>
                              </xsl:when>
                              <xsl:when test="position() mod 2 = 0">
                                    <xsl:value-of
select="format-number(.,'#')"/>
                                    <xsl:text> </xsl:text>
                              </xsl:when>
                        </xsl:choose>
                  </xsl:for-each>
            </polygon>
            </PolygonSet>
      </xsl:template>
</xsl:stylesheet>


This results to an xml output like the one following:

<?xml version="1.0" encoding="UTF-8"?>
<PolygonSet>
   <polygon>483640,4314481 483653,4314497 483697,4314548 483640,4314481
</polygon>
   <polygon>483168,4314455 483171,4314466 483184,4314517 483203,4314600
483205,4314605 483168,4314455 483199,4314726 483199,4314729 483193,4314853
483199,4314726 </polygon>
</PolygonSet>

If now i also want to make use of the code you sent me in order to mark
ORDINATE_ITEM element's
content whose position is specified like :
position() =
     /ROWSET/ROW/SHAPE/ELEM_INFO/ELEM_INFO_ITEM[position() mod 3 = 1]
by adding a d infront of them, can it be achieved through this same
stylesheet?



I tried adding another <xsl:when statement  to the when node-set of the
previous stylesheet like

<xsl:when test="position() =
/ROWSET/ROW/SHAPE/ELEM_INFO/ELEM_INFO_ITEM[position() mod 3 = 1]>
<xsl:text>d</xsl:text><xsl:value-of select="."/>
</xsl:when>

or

<xsl:when test="position() =
/ROWSET/ROW/SHAPE/ELEM_INFO/ELEM_INFO_ITEM[position() mod 3 = 1]>
<xsl:value-of select="concat('d',.)"/>
</xsl:when>

but it didn't work.

I also tried adding a second template to the previous stylesheet like:

<xsl:template match="SDO_ORDINATES_ITEM[position() =
     /ROWSET/ROW/SHAPE/SDO_ELEM_INFO/SDO_ELEM_INFO_ITEM[position() mod 3 =
1]]">
            <xsl:copy>
                  <xsl:text>d</xsl:text>
                  <xsl:value-of select="."/>
            </xsl:copy>
      </xsl:template>
but it was also ignored.


The output i am aftering will just have the character d added in front of
the relevant
ORDINATE_ITEM values in the polygon content string:


<?xml version="1.0" encoding="UTF-8"?>
<PolygonSet>
   <polygon>d483640,4314481 483653,4314497 483697,4314548 483640,4314481
</polygon>
   <polygon>d483168,4314455 483171,4314466 483184,4314517 483203,4314600
483205,4314605 483168,4314455 d483199,4314726 483199,4314729 483193,4314853
483199,4314726 </polygon>
</PolygonSet>

Do you think that i will definitely have to use a second stylesheet in
order to obtain
this output, or can it also be managed through the same stylesheet?


I understand i may be making questions with obvious answers but i don't
think that
my mind works properly right now.

Please send me any comments, and excuse me if i have bothered you again for
something obvious.
