I think he probably means a piece of software which automatically looks at the html on a page and gets (parses) the content. A search engine, for example, might look at the markup of a web page in order to index it. Or something like the built in reader view in mobile safari which strips out everything but the text. It has to parse the content in order to work out what to keep.
