Moving nodes using Transformer

Hi all,

I'm new of Apache Sling, and I'm interested in the output rewriting
pipeline. What I want to achieve, within my html page, is to move certain
nodes (stylesheets and javascript) from the middle of the HTML document to
the <head> element.

The document is generated by a CMS, so I cannot control in advance where
stylesheets and scripts will be inserted.

Can this task be achieved using a Transformer? I suppose that I can do this
on the endDocument event, but I don't know how to flow through the entire
page to move nodes.

Thanks in advance,
Omar

You can certainly write an XSLT transform to do that, triggered by a
Sling Output Rewriting Pipeline.

That will probably cause the transformer to buffer the whole output,
might become inefficient depending on the input's size.
