Hi, I'm totally new to parsing, working on a linguistic side project. I'm trying to parse something that looks like this: "<pc>1,1<k1>a<k2>a<h>1<e>1\n<hom>1.</hom> <s>a</s>", where <pc>1,1 , <k1>a is a first type of tag, and <s>a</s> is another type of tag. I would like to get something like {:pc "1,1" :k1 "a" :k2 "a" :h "1"} for starters, because the second part should be simple xml. I've got this, which works as long as the string doesn't contain anything else, but breaks on the entire sample:

"
S = {tag}
tag = <tag-open> + key + <tag-close> + value
key = #'[a-zA-Z0-9]+'
value = #'[a-zA-Z0-9]+'
tag-open = #'<'
tag-close = '>'
"

I feel like I'm missing an understanding of some basic piece. I also don't know how to separate xml tags from these first kind of tags. Please help.
