Yes you can tokenize this with a regular expression and extract the valid start and end tags.
If comments in XHTML could nest you would have a problem. But this is not the case.
- hk__2 7y ago> Yes you can tokenize this with a regular expression and extract the valid start and end tags. So you need more than a regular expression, hence your premise is incorrect.
- unlinkr 7y agoNo, you don't need more than a regular expression. If you want to extract elements, i.e. match start tags to the corresponding end tags, then you need a stack-based parser. But just to extract the start tags (which is the question) a regular expression is sufficient. The original question is a question about tokenization, not parsing, which is why a regular expression is sufficient.
