You can't get a literal size of the file, because the XSLT processor doesn't see a simple text file, but a tree of nodes. However, you can use the XPath function string-length() to get a character count of textual nodes. Given an XML input of <document> <content>Some text</content> <content>Some other text</content> </document> The following XSLT stylesheet: <?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:strip-space elements="document"/> <xsl:template match="/"> <xsl:value-of select="string-length(document)"/> </xsl:template> </xsl:stylesheet> will output 24. Note that xsl:strip-space is used to remove all whitespace nodes within the <document> element--if you omit it, then the result from the sample input will be 31 (three newlines and four spaces that indent the <content> elements). This in no way corresponds to the physical size of the XML file on your disk, but this may suit your purposes. hth, b. | brian martinez brian.martinez@xxxxxxxxxxx | | lead gui programmer 303.357.3548 | | cheap tickets, part of trip network fax 303.357.3380 | | 6560 greenwood plaza blvd., suite 400 englewood, co 80111 | | cendant travel distribution services http://www.cheaptickets.com/ | XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
