Subject: [PATCH] Add xmlHaltParser() to stop the parser
|
|
|
6dedca |
To: libvir-list@redhat.com
|
|

|
|
|
6dedca |
The problem is doing it in a consistent and safe fashion
|
|
|
6dedca |
It's more complex than just setting ctxt->instate = XML_PARSER_EOF
|
|
|
6dedca |
Update the public function to reuse that new internal routine
|
