question: protected String patchName ( String qname ) { final int lastColon = qname . lastIndexOf ( ':' ) ; if ( lastColon > 0 ) { final int firstColon = qname . indexOf ( ':' ) ; final String prefix = qname . substring ( 0 , firstColon ) ; final String localName = qname . substring ( lastColon + 1 ) ; final String uri = m_prefixMap . lookupNamespace ( prefix ) ; if ( uri != null && uri . length ( ) == 0 ) { return localName ; } else if ( firstColon != lastColon ) { return prefix + ':' + localName ; } } return qname ; }
target:  If at runtime, when the qname of the attribute is known, another prefix is specified for the attribute, then we can patch or hack the name with this method. For a qname of the form "ns?:otherprefix:name", this function patches the qname by simply ignoring "otherprefix". TODO: This method is a HACK! We do not have access to the XML file, it sometimes generates a NS prefix of the form "ns?" for an attribute.
