Currently if a title has XML elements in it, eg "Hello <literal>World</literal>" the fixed URL would be Hello_literalWorldliteral. As such the XML Elements should be stripped from the XML as well.
Fixed in 0.26.0 The builder will now remove XML elements from the Fixed URL's when it creates them. Cause: XML Elements weren't removed from the string before the it was escaped (or at all for that matter) Consequence: The fixed URL's were created with the XML element names in the URL. Since the XML is used for formatting and styling only this made the URL messy. Fix: Remove the XML elements from the string before it is escaped. See the createURLTitle() method in the DocbookBuilder class for more information.
Closing and setting as current release as no QA was performed by the original reporter. If there is still an issue with this bug still than please re-open it.
