Subject: [PATCH] SAX2: Ignore namespaces in HTML documents
|
|
|
|
In commit 21ca8829, we started to ignore namespaces in HTML element
|
|
names but we still called xmlSplitQName, effectively stripping the
|
|
namespace prefix. This would cause elements like <o:p> being parsed
|
|
as <p>. Now we leave the name untouched.
|
|
|
|
Fixes #508.
