XML structure generator
Posted: Thu Dec 22, 2016 3:20 pm
Hi.
It's dirty, quickly-made and ... so on ^^
But anyway it is better than declaring structures manually.
* How to use?
1) Save code to a some file
2) Put your XML into a "xml.txt" file around
3) Run code and copy required structures declarations from debug
4) Use ExtractXMLStructure() with those declarations to make XML parsing some easier
Also see the code for something to change, etc.
For now It can't build one structure describing whole XML tree, just produces lot of separated structures.
PS. Also maybe there was some better made already, just didn't found and was simplier to make my own than search a lot
UPDATE: the code below is outdated, here is UI tool instead:
