Silent failure if ampersand is not closed out with a semicolon for entity

[drbitboy]

Describe the bug

Partial parse of incomplete entity (ampersand without closing semicolon) returning indication of neither completion nor error.

To Reproduce

• ###from top directory of repo:
• cd libs/indicore/
• ###fix errors and warnings in test code:
• sed -i -e '/str = malloc/s/malloc/(char*) &/' -e '/%d",.*sprXMLEle/s/d",/l&/' lilxml.cpp
• g++ -DMAIN_TST -o ./lilxml lilxml.cpp
• echo '<root value="&xxx">321</root>' | ./lilxml
  • no output
• echo '<root>x &amp</root>' | ./lilxml
  • no output

Expected behavior

• EITHER generate an error because the sequences &xxx< and &xxx" are invalid entities,
• OR accept &xxx as a non-entity string

Screenshots
