Xalan keeps an internal cache of the documents, so it shouldn't be recreating a source tree or parsing each time. I suspect you are running into a variable bug that has since been fixed. We just released Xalan 1.0.0, so I suggest you try that. BTW, Xalan-specific questions are better posted on the Xalan dev list (you can subscribe at http://xml.apache.org/mail.html). The xsl-list should be reserved for XSL specific questions. -scott Brad Sommerfeld <bsommerfeld@xxxxxxx> To: "'XSL-List@xxxxxxxxxxxxxxxx'" <XSL-List@xxxxxxxxxxxxxxxx> Sent by: cc: (bcc: Scott Boag/CAM/Lotus) owner-xsl-list@mulber Subject: document() runs out of memory rytech.com 03/21/00 02:31 PM Please respond to xsl-list I am using the document function to read in external files but seem to be exceeding my memory limits. I believe it is because the previously read files are still being held in memory but I don't know how to remove them. The main template is: <xsl:template match="/"> <xsl:for-each select="document('all_forms_list.xml')/someURIs/file/text ()"> <xsl:variable name="contents" select="document(string(.))"/> <xsl:apply-templates select="$contents//XFDL"/> </xsl:for-each> </xsl:template> There is a single document all_forms_list.xml which is a list of URI's to be read. When the list gets to about 250 URI's the parser exists with an out of memory exception. I am using Apache Xalan 0.19.2 with 256meg of memory on a pentium running NT 4.0. I ran a test to determine if it was the input or the output trees that were exceeding the memory and concluded that it was the inputs. I doubled the size of the output tree (by executing the templates 2X) and still failed at the same number of inputs even though my outputs went from ~3000 lines of XML to ~6000 lines of XML. I'm afraid that the variable $contents is being created scoped within the for-each and that I'm getting a new one everytime but I don't know how to prevent it. Any ideas?
