Associating Stylesheets with XML Documents
CSS stylesheets are primarily intended for use in web pages.
Web browsers find the stylesheet for a document by looking for
xml-stylesheet
processing instructions in the prolog of the XML
document. This processing instruction should have a type
pseudo-attribute with the value text/css
and an href
pseudo-attribute whose value is an
absolute or relative URL locating the stylesheet document. For

stylesheet in Example 13-2
(recipe.css) to the file in Example 13-1 (cornbread.xml), if both are found in the
same directory:
<?xml-stylesheet type="text/css" href="recipe.css"?>

pseudo-attributes, the
xml-stylesheet
processing
instruction can have up to six pseudo-attributes:
type
This is the MIME media type of the stylesheet;
text/css
for CSS andapplication/xml
(nottext/xsl
!) for XSLT.href
This is the absolute or relative URL where the stylesheet can be found.
charset
This names the character set in which the stylesheet is written, such as UTF-8 or ISO-8859-7. There’s no particular reason this has to be the same as the character set in which the document is written. The names used are the same ones used for the
encoding
pseudo-attribute of the XML declaration.title
This pseudo-attribute names the stylesheet. If more than one stylesheet is available for a document, the browser may (but is not required to) present readers with a list of the titles of the ...
