Given a html document, what is the most correct and concise regular expression pattern to remove the query strings from each url in the document?
You can’t usefully parse HTML with a regexp. If you know the format of the page in advance — eg.
then you can just about get away with it, but for general [X]HTML a regexp parser is unsuitable.
Depending on what language you’re using, you’d need to find either an HTML parser library (eg. Python’s BeautifulSoup), or an HTML tidier combined with a standard XML parser, then scan the document for < a> elements (and maybe others, eg. < img> if you’re interested in those?), then split the attribute value on ‘?’.
