I'm trying to split up a 13GB xml file into small ~50MB xml files with this XSLT style sheet.

But this process kills xsltproc after I see it taking up over 1.7GB of memory (that's the total on the system).

Is there any way to deal with huge XML files with xsltproc? Can I change my style sheet? Or should I use a different processor? Or am I just S.O.L.?

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"

                xmlns:exsl="http://exslt.org/common"

                extension-element-prefixes="exsl"

                xmlns:fn="http://www.w3.org/2005/xpath-functions">

<xsl:output method="xml" indent="yes"/>

<xsl:strip-space elements="*"/>

<xsl:param name="block-size" select="75000"/>



<xsl:template match="/">

        <xsl:copy>

                <xsl:apply-templates select="mysqldump/database/table_data/row[position() mod $block-size = 1]" />

        </xsl:copy>

</xsl:template>



<xsl:template match="row">

        <exsl:document href="chunk-{position()}.xml">

        <add>

                <xsl:for-each select=". | following-sibling::row[position() &lt; $block-size]" >

                <doc>

                        <xsl:for-each select="field">

                        <field>

                                <xsl:attribute name="name"><xsl:value-of select="./@name"/></xsl:attribute>

                                <xsl:value-of select="."/>

                        </field>

                        <xsl:text>&#xa;</xsl:text>

                        </xsl:for-each>

                </doc>

                </xsl:for-each>

        </add>

        </exsl:document>

</xsl:template>
