Regex to detect natural language fragment

Hey,

I'm not sure if this is possible, and if it's not, I'll explore a better
way to do this.

I would like to write a script which analyzes if a line of text is (likely)
a broken natural language sentence, i.e., it is probably part of a
sentence, even if the start or end is not present, rather than it being a
fully "complete" linguistic entity, for example, a header of a section,
which does not have a period at the end and is not really a sentence, yet
is in a complete and unbroken form.

I'm pretty sure in principle this will require some kind of syntax parsing.
I think I read somewhere regular expressions for some mathematical reason
cannot parse tree / nested structures, for example HTML.

Does anyone know what some next most ubiquitous, standard tool is for
analyzing nested linguistic structures? Is that an XML parser?

Thanks very much,
Julius
