[x3d-public] HAnim Joints, Segments, Sites DEF substitution algorithm

[John Carlson]

I'm stumped for a while.  I need to talk to a teddy bear.

I'd like to prefix all the DEFs for my HAnimJoints, HAnimSites, and
HAnimSegments and all references to them with a prefix, say "Senior_"

Right now, I loop through the file, pulling in all HAnim DEF values into a
HashMap, mapped from old DEF value to new DEF value.  Then I examine each
line, trying to substitute the  "word" or occurrence of an old DEF value to
the new DEF value.  I have a little loop that goes through the whole hash
map for each line.  It is extremely slow.

I have thought of storing patterns in the hash map, but I've not done that
before.

Perhaps I should code this up in Rust or C?  Does someone know a good
native hash map implementation for  Rust/C/C++ or something as fast?

Thanks!

John
