how to generate striped table?

[alepac]

Hi everybody!

this is my first post here but I would like to start saying thank you 'cos even if I never wrote here I read so many useful posts!

Here is the issue coming...

I need to generate an html table for a prods catalogue starting from xml.

So, it has been easy to get the data I need but it seems to be not that easy to style it up!

I'll let the code speak for me now...

[code=txt]
<table>
<xsl:for-each select="Fields/field">
<xsl:if test="not(conta ins(pName, 'blabla') or pValue = '' or @hiddenField='t rue')">
<tr>
<td class="label">
<xsl:text> • </xsl:text>
<xsl:value-of select="pName"/>
</td>
<td class="value">
<xsl:value-of select="pValue"/>
</td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
[/code]

so the DREAM is to have something like a counter to find out if a row is odd or even and then to give it a class (like tr class=evenrow ..)

Of course the first idea I had was to check the value of position() of a node but since I dont get all the nodes (because of the if condition) the value i get it's useless...

Does anybody know some trick or just some easy solution for this?
I know it probably can be a really stupid question for you but I'm a newbie with xsl and xpath...I'm founding it really exciting and in few days i learnt a lot but...not enough to solve this :)

thanks in advance for any help!

You could have something like
[code=xml]
<xsl:variable name="position" >
<xsl:choose>
<xsl:when test="position( ) mod 2 = 0">evenrow</xsl:when>
<xsl:otherwise> oddrow</xsl:otherwise>
</xsl:choose>
</xsl:variable>

<tr class="{$positi on}"/>
[/code]
Note, use of braces {} in the attribute that tells the processor that this is an xpath to be evaluated as opposed to a string.

If you want this only on your filtered rows, you have to move the if test to the for-each like so:
[code=xml]
<xsl:for-each select="Fields/field[not(contains(pN ame, 'blabla') or pValue = '' or @hiddenField='t rue')]">
[/code]
and get rid of the if element.

you cant imagine how stupid (and grateful to you) i feel!

i had the key! i could get the position to filter my table elems but...i was not filtering them all together in the for-each! that's it!!! there was no reason to have a for-each and then a xsl if after! having them together i get just the elements I want and THEN i can use the position element! I obviously need to learn a little more xpath stuff :D

I was looking for a really difficult solution for a really difficult problem when I could make the problem....real ly easy! Thanks for the help! thanks a lot!!! :)



and...thank you again!!! :)
