If you get errors complaining of undefined entities like when
parsing xhtml it means you need to install the DTD for xhtml 1.0 or
1.1.
Example of a doctype for xhtml 1.1:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
You want to install the DTDs locally following the model in /etc/xml.
If you don't libxml will fetch the DTD from www.w3.org each time you
parse a document. Needing to install these DTDs was not obvious to me
and should be part of the documentation. There a rpm for xhtml 1.0 -
"xhtml1-dtds-1.0-7". I couldn't find one for xhtml 1.1 so I downloaded
it piecemeal from w3.org.
Installing the DTD does not automatically turn on validation. If you
want to validate you need to turn it on:
XML:
arser::default_validity_checking =3D TRUE
XML:arser::default_load_external_dtd controls the loading of the
'external subset' (the definition for the character entities like
&. It is defaulted to TRUE.
XML:arser::default_load_external_dtd is broken. This fixes it.
