Directly parsing fragments causes <application> tags to be skipped

[atesgoral]

The Wireshark dictionary files are meant to be used as includes in the parent dictionary.xml file:

<!DOCTYPE dictionary SYSTEM "dictionary.dtd" [
	<!-- Any files added here need to be added to Makefile.am and
	     packaging/nsis/wireshark.nsi -->

	<!ENTITY nasreq			SYSTEM "nasreq.xml">
	<!ENTITY eap			SYSTEM "eap.xml">
	<!ENTITY mobileipv4		SYSTEM "mobileipv4.xml">
	<!ENTITY chargecontrol		SYSTEM "chargecontrol.xml">
	<!ENTITY sunping		SYSTEM "sunping.xml">
	<!ENTITY TGPP			SYSTEM "TGPP.xml">
         ...
	&nasreq;
	&eap;
	&mobileipv4;
	&chargecontrol;
	&sunping;
	&TGPP;
         ...
</dictionary>

The proper way to parse these dictionaries would be to use an XML parser that will interpret <!ENTITY ... SYSTEM ...> to include these fragments, but sax-js isn't such parser.

The problem with the current approach of parsing individual files like TGPP.xml is, they contain more than one <application> root tag. They are invalid XML since there needs to be only one root tag. The SAX parser that is currently being used just ignores the additional <application> tags, leading to many AVPs to be excluded from the compiled dictionary.

I might have a fix for this...
