Parameter

Parameter	Description
xslSrc	StreamSrc containing the xsl transform
docSrc	StreamSrc containing the document to be transformed
params	Map of properties to set on the transform
resolver	URIResolver instance to resolve URI's in the output document.

Exception

Parameter	Description
TransformerConfigurationException	if the TransformerFactory fails to create a Transformer.
TransformerException	if actual transform fails.

Return

StringBuffer containing the XML results of the transform

Declaration

protected static final StringBuffer transformXml(final StreamSource xslSrc, final StreamSource docSrc,
