Re: [xsl] Can one Use JavaScript to update XSL:Variables

[Marcus Andersson <marcus@xxxxxxxxxx>]

You can use <xsl:param name="page"/> to send values into a transform from "outside".

You can do:

<xsl:stylesheet ...>
  <!-- 1 is the default here if you don't pass the param-->
  <xsl:param name="page" select="1"/>

  ...
</xsl:stylesheet>

And then you use the param as if it were a <xsl:variable/> and it's global.

How you pass the param into the stylesheet depends on the XSLT engines API you are using but if you're doing 
this client side I would recommend to look into Sarissa (sarissa.sourceforge.net).
