How do I have to escape > (?) those quotes to get a well-formed XPath string? there are some examples of this in the archive, but... First just consider the xpath syntax. You can use " or ' to delimit a string literal, so if you only want one then you can delimit with the other. "'" or '"' if you want both then you can not do it directly in a string literal but you can construct the string '" using translate('a"','a',"'") or concat("'",'"') or if you drop out of xpath, to xslt <xsl:variable name="x">'"</xsl:variable> then use $x as this result tree fragment will coerce to a string. Then you need to get one of those expressions into an XML attribute If you use " to delimit the attribute value then you need to quote " so you end up with select="translate('a"','a',"'")" which looks a bit odd but the XML parser eats that and gives the xpath system translate('a"','a',"'") which takes the string a" and replaces the a by '. I was thinkin about something like selectNodesParametrized (node, "/element[@attr ='$$']", variableString); isn't that just select="/element[@attr = $variableString]" ? or perhaps I didn't understand the question.
