Re: How to include a single quote in a parameter strin

When this gets read by an XML parser, it reports the value of the
select attribute to the XSLT (or rather XPath) processor to be:

  'NRC Research Press: Revue du génie et de la science de
   l'environnement'

In other words, it's the XML parser's job to resolve the &#x0027;
character reference into the ' character; that's already been done by
the time it gets to the XPath processor.

The XPath processor then tries to parse that value as an XPath. It
pairs the first ' with the second ' and then tries to parse the part
after the second ' as being an operator on that string, which is why
you get the error.

The solution is to make sure that the XPath processor gets a string
that it can parse as an XPath, and since your string has a ' in it,
that means using " to delimit the string rather than ':

  "NRC Research Press: Revue du génie et de la science de
   l'environnement"

Then you can move that into the XML either by delimiting the attribute
value with double quotes and escaping the double quotes in the XPath:

<xsl:param name="fjeestitle"
  select="&quot;NRC Research Press: Revue du génie et de la science de
   l'environnement&quot;" />

or by delimiting the attribute value by single quotes and escaping the
single quote in the XPath:

<xsl:param name="fjeestitle"
  select='"NRC Research Press: Revue du génie et de la science de
   l&apos;environnement"' />

Cheers,
