XSL modifying the href attribute of an html <a> tag

I am rather new to XSLT and was wondering how I can modify the href attribute of a tag with a value acquired from an XML node.

In particular, my XML file goes like this

<root>
<privileges edit="1" del="1"></privileges> 
<rooms> 
<room> 
<id>1</id> 
<roomNr>101</roomNr> 
<locked>0</locked> 
<lockdownReason></lockdownReason> 
</room>
</rooms>
</root>

and my XSL file goes like

<xsl:for-each select="root/rooms/room">
<div 开发者_如何学运维class="column toolbox">
<xsl:if test="$edit = 1">
<a href='admin.php?room=VALUE_OF_ID__OF_CURRENTLY_SELECTED_NODE'>this is a link</a>
<p>edit is true</p>
</xsl:if>
</div>
<div class="column">Room Nr.:<xsl:value-of select="roomNr"/></div>
</xsl:for-each>

the capital letters indicate what I try to accomplish. Someone please be kind enough to reply. Thanks

For your XSLT, the easiest thing would be to use an Attribute Value Template (AVT) and select the value of <id>, like this:

<a href='admin.php?room={id}'>this is a link</a>

You're looking for xsl:attribute. I'm not really sure about how the reference to the current id should look, but something like this should get you started:

<a>
<xsl:attribute name="href">admin.php?room=<xsl:value-of select="./id"/></xsl:attribute>
this is a link
</a>
