Hi Jacobo,

no worries. :) Based on your description the following should be able to produce the result:

<xsl:choose>

    <xsl:when test="umbraco.library:Request('tag') = '' ">

        [do your own operations here]

    </xsl:when>

    <xsl:otherwise>

      [list nodes as above]

    </xsl:otherwise>

</xsl:choose>

This obviously is an exclusive arrangement, so if you just want to perform a couple of operations AND list the nodes you can add an if statement before listing the nodes, like

<xsl:if test="umbraco.library:Request('tag') != '' ">

   [do your own stuff here]

</xsl:if>

Hope that helps,

Sascha

Hello Sascha and thanks for helping! Sorry for not answering earlier but I've been away for a few days without Internet connection.

Following your post, I haven't been able to exactly accomplish my mission :). I now have:

<xsl:choose>
   <xsl:when test="umbraco.library:Request('tag') = '' ">

<!-- Do my operations and output successfully -->

   </xsl:when>

   <xsl:otherwise>

   <ul>
        <p>Hello world?</p>
<!--
 <xsl:for-each select="$currentPage/node [string(data 
[@alias='umbracoNaviHide']) != '1' and (umbraco.library:Request('tag') =
 '' or contains(data [@alias = 
'tags'],umbraco.library:Request('tag')))]"> -->
 <xsl:for-each select="$currentPage/* [name() = $documentTypeAlias and string(umbracoNaviHide) != '1' and (umbraco.library:Request('tag') =
 '' or contains(data [@alias = 
'tags'],umbraco.library:Request('tag')))] ">
    <li>
       <a href="{umbraco.library:NiceUrl(@id)}">
      <xsl:value-of select="@nodeName"/>
    </a>
  </li>
</xsl:for-each>
</ul>

    </xsl:otherwise>

</xsl:choose>

I am still not able to list the nodes which have the passed tag with any of the for-each statements above. I have also tried eliminating the umbraco.library:Request('tag') = '' , with the same result: no listing.

I did put the "Hello world?" to see if it at least reachs there and it effectively does, so it's not a matter on the conditional block.

Anything I'm missing?

Thanks a lot!

Hi Jacobo,

I can't see anything why the first statement shouldn't work. I assume the nodes you want to display sit directly under the node where the Xslt file is used? The alias of the property is 'tags' and you are using Umbraco v 4.0.*? Just triple checking.

I would suggest trying to eliminate one possible error after the other:

replace <p>Hello world?</p> with 
requested tag: |<xsl:value-of select="umbraco.library:Request('tag')" />|

just to see if the tag string from the request gets through okay of if there are any encoding issues etc.

Then maybe do something simple first and output all child nodes with their node name, their associated tags and if the query tag matches a node's tags:

<xsl:for-each select="$currentPage/node">
    node name: <xsl:value-of select="@nodeName" />
    <br />
    tags: <xsl:value-of select="data[@alias='tags']" />
    <br />
    has query tag: <xsl:value-of select="contains(data[@alias='tags'], umbraco.library:Request('tag')" />
    <br /><br />
</xsl:for-each>

Can you have a go with the above and let me know what that gives you?

And you are right, you definitely don't need the (umbraco.library:Request('tag') = '' statement as that has been taken care of by the outer choose statement.

Hello again and thanks for the interest!

About the triple check: The nodes are child types of the document type from which template I call the XSLT file; is that all right or should I look somewhere else. The property I have realised now is not called simply "tags" but "thm_new_tags" (the nodes are "thm_new"), more on this below. I am using Umbraco 4.5, that's why I changed the xsl:for-each statement... is there anything else I should do?

Copypasting your code (I just had to had one more parenthesis before closing the select statement) , it outputs the passed tag all right. If don't change the for-each like below instead o the $currentPage/node it outputs nothing else, so I continue using it with the new way (as far as I've understood!). I've also tried putting the alias as "tags" as well as below "thm_new_tags". The output is the same... it outputs all the nodes but all of them with no tags associated and all with the "requested tag" as "false", even the news rightly associated with the specified tag (I double checked that). Here's how the code is now:

<ul>
  <xsl:for-each select="$currentPage/* [name() = $documentTypeAlias]">
  <li>
    <span>node name: <xsl:value-of select="@nodeName" /></span>
    <br />
    <span>tags: <xsl:value-of select="data[@alias='thm_new_tags']" /></span>
    <br />
    <span>has query tag: <xsl:value-of select="contains(data[@alias='thm_new_tags'], umbraco.library:Request('tag'))"></xsl:value-of></span>
    <br /><br />
  </li>
</xsl:for-each>
</ul>

Knowing that the property is "thm_new_tags", and that I'm using Umbraco4.5... what can be missing in the picture? As I said, it does list all the nodes, but doesn't seem to be able to get their tags correctly...

Thank you so much for helping!

Hi!

Issue solved! Thanks for helping me down the road! The link you posted is something I've been looking for a while. I think I'm just confused how umbraco's documentation is spread through multiple sources.

Anyway, I indeed needed to use "thm_new_tags", only that without the first slash "<xsl:value-of select="thm_new_tags" />".

Just for the record in case someone arrives here some day, the final code goes like this:

<xsl:choose>
    <xsl:when test="umbraco.library:Request('tag') = '' ">
    <!-- do my first listing here --> 
    </xsl:when>
    <xsl:otherwise>
       <ul>
          <xsl:for-each select="$currentPage/* [name() = $documentTypeAlias and string(umbracoNaviHide) != '1' and (contains(thm_new_tags, umbraco.library:Request('tag')))] ">
                <li>
                     <span>node name: <xsl:value-of select="@nodeName" /></span>
                     <br />

                     <span>tags: <xsl:value-of select="thm_new_tags" /></span>

                     <br />

                     <span>has query tag: <xsl:value-of select="contains(thm_new_tags, umbraco.library:Request('tag'))"></xsl:value-of></span>

                     <br /><br />

                </li>
         </xsl:for-each>
     </ul>
 </xsl:otherwise>
</xsl:choose>

Thanks a lot for all the interest in my problem, this forum is awesome in terms of helping each other. Cheers!

You're very welcome, glad it worked out well in the end. :)
