XML::XPathScript::Processor is the XML transformation engine in XML::XPathScript.

SYNOPSIS

In a stylesheet ->{testcode} sub for e.g. Docbook's < ulink > tag:
my $url = findvalue('@url',$self);
if (findnodes("node()", $self)) {
# ...
$t->{pre}=qq'< a href="$url" >';
$t->{post}=qq'< /a >';
return DO_SELF_AND_KIDS;
} else {
$t->{pre}=qq'< a href="$url" >$url< /a >';
$t->{post}=qq'';
return DO_SELF_ONLY;
};
At the stylesheet's top-level one often finds:
< %= apply_templates() % >

The XML::XPathScript distribution offers an XML parser glue, an embedded stylesheet language, and a way of processing an XML document into a text output. This package implements the latter part: it takes an already filled out $t template hash and an already parsed XML document (which come from XML::XPathScript behind the scenes), and provides a simple API to implement stylesheets. In particular, the "apply_templates" function triggers the recursive expansion of the whole XML document when used as shown in "SYNOPSIS".
