Hvis du nu skal indlæse XML'en i en database der kun kan indeholde noder med eksempelvis 4000 tegn, så kan du via XSLT få klippet det overflødige.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text()">
<xsl:variable name="numlenght">
<xsl:value-of select="string-length(.)" />
</xsl:variable>
<xsl:choose>
<xsl:when test="string-length(.)<4000">
<xsl:value-of select="."/>
</xsl:when>
<xsl:when test="string-length(.)>4000">
<xsl:value-of select="substring(.,1,4000)"/>
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
I Groovy kunne man eksempelvis gøre således:
import javax.xml.stream.*
import javax.xml.transform.*
import javax.xml.transform.stream.StreamResult
import javax.xml.transform.stream.StreamSource
static final String XSLT = '''
... som skrevet ovenover ...
'''
def xml = new File(filename).getText('utf-8')
def factory = TransformerFactory.newInstance()
def transformer = factory.newTransformer(new StreamSource(new StringReader(XSLT)))
StringWriter writer = new StringWriter(xml.size())
transformer.transform(new StreamSource(new StringReader(xbrl)), new StreamResult(writer))
def cuttetXML = writer.toString()
