Passing dynamics attributes to collective.xdv inline XSL

I have the following snippet in rules.xml

<!-- Fi开发者_Go百科x search box to honour Plone rules-->
<replace css:theme="form#search">
    <form action="http://localhost:8080/LS/search" name="form1" id="search">
        <input type="text" name="SearchableText" onclick="make_blank();" onblur="keep_search();" class="search_text_style content_text2"/>       
        <input type="image" src="++resource++lsm/images/template/search.png" width="22" height="22" class="search_btn" />
</form>
</replace>

How one can pass dynamic attributes to XSL so that I cat set to be real URL based on the Plone site object?

I can do this by providing helper views, modify XDVTransform, etc. but I'd like to first know what's the recommended approach here.

Note that in plone.app.theming / Diazo, you'll be able to define parameters using TAL and pass them to your theme.

I think in this case, I'd just grab the actual search URL (or the home URL) from the content with an attribute value-of.

I think you need a global <xsl:param> for this.

Typically, the value of a global parameter is set by the initiator of the transformation just before the transformation is initiated. This is a recognized general way of passing to the XSLT transformation values that are not static (known at the stylesheet compilation time).

Here is an example:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:param name="pUrl" select="'http://www.cnn.com'"/>

 <xsl:template match="/">
  <t href="{$pUrl}"/>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the result is:

<t href="http://www.cnn.com" />

How a global parameter value is set is implementation-dependent and varies from one XSLT processor to another. Read the documentation of your XSLT processor to get the knowledge how to do this.
