Re: [xsl] Using a variable to get the value of an element

Hi Ben,

You either need an evaluate() extension function or, for this simple
case, you can use the pattern:

  *[name() = $variable]

Which locates all the elements whose name is the value of the
$variable.
  
One thing you need to watch out for in your particular example is
whitespace. The $hello variable will contain a string that looks like:

  "
   officename1_en"

To avoid that whitespace, you either have to normalize the variable
before you compare it to the name of the element:

  *[name() = normalize-space($hello)]

or you need to create the $hello variable without the extraneous
whitespace, with:

  <xsl:variable name="hello">officename1_<xsl:value-of
  select="$PageLang /></xsl:variable>

or:

  <xsl:variable name="hello">
    <xsl:text>officename1_</xsl:text>
    <xsl:value-of select="$PageLang" />
  </xsl:variable>

or:

  <xsl:variable name="hello">
    <xsl:value-of select="concat('officename1_', $PageLang)" />
  </xsl:variable>

Cheers,

Jeni
