EPrints::XSLT - utilities for XSLT processing

User Comments

SYNOPSIS

 my $xslt = EPrints::XSLT->new(
   repository => $repository,
   stylesheet => $stylesheet,
 );
 
 my $result = $xslt->transform( $doc );
 print $xslt->output_as_bytes( $result );
 

Using ept functions:

 <xsl:value-of select="ept:value('title')" />
 <xsl:copy-of select="ept:render_value('title')" />

DESCRIPTION

Because XSLT requires very careful treatment this module should probably be only used by internal code.

For the correct context to be set for 'ept:' functions this module must be used for every transform.
