Ruby has the nokogiri gem: #! /usr/bin/env ruby Use this tool to extract URLs in web pages, data files, text and more. Sample usage (including writing to file per OP request usage is the same for any script here with a shebang): $. $parser->parse(get($url) or die "Failed to GET $url") My $parser = HTML::Parser->new(api_version => 3, start_h => ) My $url = shift or die "No argument URL provided" If you can guarantee that the HTML you're parsing is fairly simple, and the stuff you're trying to extract is predictable you may be able to get away with it. Print "$href\n" if $href & $href =~ /^https?:\/\// 9 In general it's not a good idea to parse HTML with Regular Expressions, since HTML is not a regular language. | xmllint -html -xpath 2>/dev/null - \Īdditionally, Perl offers HTML::Parser: #!/usr/bin/perl This method is extremely fast and I use these in Bash functions to format the results across thousands of scraped pages for clients that want someone to review their entire site in one scrape.As discussed in other answers, Lynx is a great option, but there are many others in nearly every programming language and environment.Īnother choice is xmllint. Once the subset is extracted, just remove the href=" or src=" sed -r 's~(href="|src=")~~g' There are pre-written web crawlers available. You may need to write this yourself (or pay someone to write it). ![]() Our new code would look like: curl -Lk | sed -r 's~(href="|src=")(+).*~\n\1\2~g' | awk '/^(href|src)/,//' | awk '/^src="/,//' Answer (1 of 3): You need a type of program called a 'web crawler'. It is useful to build advanced scrapers that crawl every page of a certain website. For example, you may not want base64 images, instead you want all the other images. I want to copy all of the links from simple page of multiupload. Extracting all links of a web page is a common task among web scrapers.

The awk finds any line that begins with href or src and outputs it. 1 If you don't mind that: There is no guarantee that you find all urls. The forward slash can confuse the sed substitution when working with html. This is preferred over a forward slash (/). Notice I'm using a tilde (~) in sed as the defining separator for substitution. The first sed finds all href and src attributes and puts each on a new line while simultaneously removing the rest of the line, inlcuding the closing double qoute (") at the end of the link. curl -Lk | sed -r 's~(href="|src=")(+).*~\n\1\2~g' | awk '/^(href|src)/,//'īecause sed works on a single line, this will ensure that all urls are formatted properly on a new line, including any relative urls. I've found awk and sed to be the fastest and easiest to understand. Save your Word document as Web Page (.htm. I scrape websites using Bash exclusively to verify the http status of client links and report back to them on errors found.
