Here's the code: > > <xsl:variable name="xmTmplt"><xsl:copy-of > select="document('usr_member.xml')//FLDS"/></xsl:variable> This creates $xmTmplt as a result tree fragment. Any time the contents of xsl:variable contain a template-body, you get an RTF, which cannot be used in XPath expressions as anything but a string unless you use the node-set() extension function. A much better way to construct this variable is to use: <xsl:variable name="xmTmplt" select="document('usr_member.xml')//FLDS"/> That's still very expensive, especially if it's a large document, but it will return the desired node-set and you won't have to resort to extension functions, even though node-set() is supported by nearly all XSLT processors. hth, b. | brian martinez brian.martinez@xxxxxxxxxxx | | lead gui programmer 303.708.7248 | | cheap tickets, part of trip network fax 303.790.9350 | | 6436 s. racine cir. englewood, co 80111 | | cendant travel distribution services http://www.cheaptickets.com/ | XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
