CQWP - Get Current Web URL

Question

I am customizing the ItemStyle.xsl in SPD2010 for a CQWP crawling a whole site collection. I need to use the current web as a variable.

I tried multiple options:

• Option #1 - use server variables in a similar way to what you do with a DVWP but I do not see where I would set up the block

Ref. http://sympmarc.com/2007/10/19/data-view-web-part-parameters-based-on-server-variables/

• Option #2 - use the ddwrt namespace functions I have successfully added the namespace to the ItemStyle.xsl and it does work great to retreive the page URL

  xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime"

Ref. http://spyralout.com/2009/03/16/current-page-url-using-xsl-for-content-query-web-part/

However, when trying the same trick to retrieve Httphost, HttpVDir and other parameters, it simply didn't work (returned blank). Note: my SP website is using https...

• Option #3 - Use the parameter(s) defined in the ContentQueryMain.xsl It seems that I should be able to access the paramters defined there from the ItemStyle.xsl but I probably don't do it properly... Any help?

Answer 1

If you're doing this kind of thing often, you could create a new class that inherits from CQWP, and passes data you need through to the XSL, using the ModifyXslArgumentList method.

Answer 2

In ContentQueryMain.xsl are declared the following parameters:

• SiteUrl - URL of the current site collection
• WebUrl - URL of current web site

In ItemStyle.xsl current web site url could be specified as demonstrated below:

<a href="{$WebUrl}/_layouts/userdisp.aspx?id={$AuthorId}"><xsl:value-of select="@Author" /></a>

Note: In order to encode URL string UrlEncode function could be used
