RE: [xsl] Accessing xml node data using variable

Firstly, packing information into structured element names is bad design.
This is what attributes are for. Don't use <title-en> and <title-nl>, use
<title xml:lang="en"> and <title xml:lang="nl">.

Secondly, this doesn't work:

<xsl:value-of select="root/{$MyTitleName}"/>

You can't use curly braces inside an XPath expression, and you can't
construct XPath expressions dynamically from strings. You want

<xsl:value-of select="root/*[name() = $MyTitleName]"/>

or if you change the design,

root/title[@xml-lang=$lang]
