RE: Problem Dynamically Building Query String In XSLT

After getting two excellent and informative responses, I went with the
following (note, there is one change in the last line of the code. I
moved one of the parentheses):

<xsl:value-of select="substring($u, 1, string-length($u) - 1)"/>

This works beautifully!

Thanks for your help!

Given the limitations of 1.0, where you can't manipulate sequences of
strings, or create and then process temporary trees, I would do:

<xsl:variable name="u">
  <xsl:text>pagename.aspx?</xsl:text>
  <xsl:if test="$varTarget">
    <xsl:text>target=</xsl:text>
    <xsl:value-of select="$varTarget">
    <xsl:text>&amp;</xsl:text>
  </xsl:if>
  <xsl:if test="$varPage">
    <xsl:text>page=</xsl:text>
    <xsl:value-of select="$varPage">
    <xsl:text>&amp;</xsl:text>
  </xsl:if>
  .. repeat for other parameters
</xsl:variable>
<xsl:value-of select="substring($u, 1, string-length($u - 1))"/>

that is, add an & after every parameter, then at the end strip off the
last
character of the string.
