Hello

I am trying to write a function that suppose to have an inside counter that updated after each loop. I will try to explain with an example:
counter = 10.
for(temp1>0)
   { for the 1st 4
     do something with name=current1
     temp1--
     )
for the second 4 do the same thing, but now give name=current2 and so on
until temp1=0.

I am having difficulties to do the inside loop and to write the method. the method that I have is:


<xsl:if test = "$counter-db_columns[@class='statistic']">
  <xsl:for-each select = "counter > 0">
    <case>
       <xsl:attribute name = "v2">
     <xsl:value-of select="concat'STATISTIC_COUNTER_', $current)"/>
       </xsl:attribute>
       <xsl:for-each select = "$counter-db_columns[@class='statistic']">
        <column>
            <xsl:attribute name = "name">
                <xsl:value-of select="@dbcolumn"/>
                </xsl:attribute>
        </column>
    </xsl:for-each>
     </case>
   </xsl:for-each>
</xsl:if>

Hope it was clear enough
Thank for the help

XSLT is a functional language, not a procedural one, and you are attacking your problem in a procedural way. Instead of describing the code you want to write (and can't write), it's better to describe what you want your function to do: what is its input, and what is it's output?

the input is:
10 times the for will run on $counter-db_columns[@class='statistic']
(I have 10 classes of name statistic).

the required out put is:
divide this input $counter-db_columns[@class='statistic'] into groups of 4.
to each group to give an unique name.
I should have 3 groups (first 2 groups with 4 classes, and one group with 2 classes).
each should have a unique name.

hope that this is more clear and correct in XSLT matter.

Try this:

<xsl:for-each select="$counter-db_columns[@class='statistic'][position() mod 4 = 1]">
  <group name="name{position()}">
    <xsl:variable name="start" select="(position()-1)*4 + 1"/>
    <xsl:copy-of select="$counter-db_columns[@class='statistic'][position() &gt;= $start and position() &lt; $start+4]"/>
  </group>
</xsl:for-each>

It can be made a bit less verbose in XSLT 2.0

this is correct in general, but it still doesnt solve the main problem. since in the input there are a lot of $class=statistic, I run in a for loop to get over all the $claa and to rap it in a counter and I get more counters then needed.

the input:
                        <xsl:for-each select = "$counter-db_columns[@class='statistic']">
                            <xsl:call-template name="common-time-display-statistic">
                                <xsl:with-param name="v2" select="@dbcolumn"/>
                                <xsl:with-param name="display" select="/etd/counters/counter/data[@class='statistic']/../display/@sum-format"/>
                                <xsl:with-param name="column_key" select="@dbcolumn"/>
                                <xsl:with-param name="column_display" select="concat($tech_id,'-', @dbcolumn)"/>

you can see the there is 2 extra un needed output (statistic_counter_3/4, they are empty and should be calculated.)

sorry for the long mail, hope this is clear enough.
thanks for the help.

Sorry, but there's no way I'm going to read that amount of code. Try a cut-down example - you probably won't need to post it, because you'll be able to debug it yourself.
