> For example my XML would be as follows: > <AAA> > <BBB>123</BBB> > <BBB>456</BBB> > <BBB>-</BBB> > <BBB>789</BBB> > </AAA> > > <xsl:variable name="TotalSum" select="sum(AAA/BBB[not '-'])"> > That should be rejected as a syntax error. Try <xsl:variable name="TotalSum" select="sum(AAA/BBB[not(.='-')])"> or if you want to reject all the non-numeric ones <xsl:variable name="TotalSum" select="sum(AAA/BBB[number(.)=number(.)])"> (That's weird, it relies on the fact that the only number that isn't equal to itself is NaN) Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
