What is an "xml-stylesheet reference" exactly? If you mean a processing that attaches an xsl stylesheet (eg `<?xml-stylesheet type= "text/xls" href="xls_style.xlss"?>`, then it's a processing instruction, and can be inserted as a regular PI: create an element with a tag of '#PI' and set its target to `xml-stylesheet` (using `set_target`) and its data to `type= "text/xls" href="xls_style.xlss"` (using `set_data`). Does this help?	[reply] [d/l] [select]

how do I get the PI to appear at the beginning of the document? `my $xsl = new XML::Twig::Elt('#PI'); $xsl->set_target('xml-stylesheet'); $xsl->set_data('type= "text/xls" href="xls_style.xls"'); $xsl->paste('before', $twig->root);` [download] This fails because you can't paste before the root.

Now you are entering the dark realm of comments and processing instructions before and after the root... be afraid, very afraid! The answer: you have to replace the `paste` by `$twig->_add_cpi_outside_of_root( leading_cpi => $xsl);`. Which I agree is slightly weird, not to mention totally undocumented. This might actually be worth a method of its own. What about `add_stylesheet( $stylesheet_url )`?	[reply] [d/l]

Yep! I wasn't sure what a PI was. Thanks for your help.	[reply]
