One way to handle those characters is to use the translate() function to remove them before doing the test. If the third argument of translate() is empty, then the matching characters in the second argument disappear, and all other characters are left untouched. Something like:
string(number(translate(., '<>', ''))) Bob Stayton Sagehill Enterprises [email protected] ----- Original Message ----- From: Xmplar To: Bob Stayton Cc: DocBook Apps Sent: Thursday, May 24, 2012 7:38 PM Subject: Re: [docbook-apps] Aligning numbers in table cells with xsl I managed to (almost) fix the problem by adding a test for NaN to the string variable: <xsl:if test="(ancestor-or-self::d:table/@tabstyle = 'numbers' or ancestor-or-self::d:table/@tabstyle = 'numberstripe') and not(ancestor::d:thead or ancestor::d:tfoot) and preceding-sibling::d:entry and (string(number(.) != 'NaN'))"> This however will not select any cells that have a number and a non-numeric string (such as greater than or less than signs: <1, or >20) - my test treats those cells as a string and not as a number. I now need to find how to convert < and > to a number so that the test selects cells with a number and a lt or gt sign.
