Maybe this just reinforces your point, but someone experienced with a procedural language will understand that "=" is an assignment operator and "==" is an equality operator; however, in XSLT "=" is an equality expression and <xsl:variable> is the assignment "operator." That wouldn't see terribly intuitive to me if I were just learning the language. (Although your programming mistake above, written as <xsl:if test="$i = $j">, would make perfect sense to me now!) cheers, b. | brian martinez brian.martinez@xxxxxxxx | | senior gui programmer 303.708.7248 | | trip network, inc. fax 303.790.9350 | | 6436 s. racine cir. englewood, co 80111 | | http://www.cheaptickets.com/ http://www.trip.com/ | XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
