Subject: Move omit-node part from startElement to endElement to allow nodes
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=54065b59a1034308e86a8d9dbf0b202361074822;p=simgear.git

Move omit-node part from startElement to endElement to allow nodes
of this type to have children. We have to save the omit state on the
stack for that.
