Re: [xsl] Creating strings with apos and replacing

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Some general rules:

* In an XML attribute using double quotes as delimiters, write double quotes
as "
* In an XML attribute using single quotes as delimiters, write single quotes
as '

The above replacements give you the string that XPath sees, which should then
follow the rules:

* In a XPath 2.0 string literal using double quotes as delimiters, write
double quotes as two double quotes.
* In a XPath 2.0 string literal using single quotes as delimiters, write
single quotes as two single quotes.

Another option which I like to use in XSLT is:

<xsl:variable name="apos" as="xs:string">'</xsl:variable>
<xsl:variable name="quot" as="xs:string">"</xsl:variable>

and then you can write XPath expressions such as "He said, " || $quot " || "I
don" || $apos || "t" || $quot".

But 4.0 gives you another option: `He said, "I don't"` where the string is
written between backticks.
