I'm transforming a parse tree for my needs, using `org-element-map', but since this functions returns what it mapped and, as Nicolas pointed out, its kind of fruitless to map top-level 'org-data type (since it has no property list), I store the parse-tree in some global variable that gives me easy access to the whole (modified) parse-tree. But its not really about storing something, thats just for convenience. I can (and do) wrap `org-element-map' into a function that receives a complete parse-tree and returns a complete parse-tree after modifying some parts of it (without storing something). > What does the parse-tree store? its just about a complete parse-tree as produced by `org-element-parse-buffer' transformed into a different syntax in several steps. > Does the buffer of which it is a representation change, when the parse > tree changes. no, the parse-tree is only prepared to be digested by a different programming-language. > How are you trying to "use" the parse tree?

I don't want to talk too much about the project until I know its going to work out. When there is something tangible I will announce it... -- cheers, Thorsten
