Question
How do I put single or double quotes into an XPath string?
I'd like to set a JET variable to the value 'ABC' (including the single quotes).
Answer
As of JET 0.9, you can make use of XPath quote escaping and/or quote escaping in JET tag attributes.
<%-- using doubled single quotes (') to indicate an literal single quote character --%> <c:setVariable var="var" select=" '''ABC''' "/>
To do double quotes ("ABC"), you could do either of the following:
<%-- surround the select attribute value with single quotes -- and using doubled double quotes (") to indicate an literal double quote character --%> <c:setVariable var="var" select=' """ABC""" '/> <%-- using \" indicate to the tag attribute parser a literal double quote character. -- The XPath parser then needs no escaping --%> <c:setVariable var="var" select=" '\"ABC\"' "/>
</pre>
In older JET versions, you have to resort to a bit of Java code to define variables containing the quote strings:
<% context.setVariable("dquote", "\""); // $dquote = a double quote context.setVariable("squote", "'"); // $squote = a single quote %> <c:setVariable var="var" select="concat($squote,'ABC',$squote)"/> <c:setVariable var="var" select="concat($dquote,'ABC',$dquote)"/>
