[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Getting useful data from this XML
 They call this an XML feed?
I struggled with this at first, until I realized that they have not only
committed the crime of escaping the nested markup so that < is written as
<, they have actually double-escaped it so that it is written as &lt;
This must be the most perverse XML document I have seen for a long time.
Using disable-output-escaping will compensate for a single level of
unnecessary escaping in the input, but it won't compensate for two levels.
If your project allows you to use Saxon, I would suggest
<p>1) <xsl:value-of select="saxon:parse(concat('<d>',
@description, '</d>'))"
disable-output-escaping="yes"
xmlns:saxon="http://saxon.sf.net/"/></p>
which does the trick. Horrible input sometimes demands a horrible
stylesheet.
