NAME
Petal::Canonicalizer::XHTML - Builds an XHTML canonical Petal file
DESCRIPTION
This modules mainly implements the XML::Parser 'Stream' interface. It receives XML events and builds Petal canonical data, i.e.
<foo petal:if="bar">Hello</foo>
Might be canonicalized to something like
<?petal:if name="bar"?>
<foo>Hello</foo>
<?petal:end?>
On top of that, Petal::Canonicalizer::XHTML will self close certain XHTML specific tags, like <br /> or <input ... />
StartTag
Called for every start tag with a second parameter of the element type. It will check for special PETAL attributes like petal:if, petal:loop, etc... and rewrite the start tag into @Petal::Canonicalizer::XML::Result accordingly.
For example
<foo petal:if="blah">
Is rewritten
<?petal:if name="blah"?><foo>...
EndTag
Called for every end tag with a second parameter of the element type. It will check in the @Petal::Canonicalizer::XML::NodeStack to see if this end-tag also needs to close some 'condition' or 'repeat' statements, i.e.
</li>
Could be rewritten
</li><?petal:end?>
If the starting LI used a loop, i.e. <li petal:loop="element list">
