5,377 PointsOutputting <title></title> content from HTML
Original Question: "Writing a program that reads from a public web page and looks for the title of the page. The program should then output the contents of the page title to STDOUT using an ERB template."
My problem: I've been able to retrieve the HTML of a webpage and save it to a txt file; however, i'm a bit confused as to how I can get the program to output the content of the <title> element. I know that I can find the <title></title> tags using .include?(), /title/, etc., but when it comes to actually outputting the content, i'm a bit lost.
Without telling me the answer, would someone mind maybe pointing me in the right direction or giving me a hint?
In other words, if the title is
<title>My Name</title>
How can I get ruby to search the .txt file and spit out "My Name"?
Thank you!

475 PointsI don't know Ruby myself, but my best guess would be to use regular expressions. Something like <[^>]+> allows you to find opening and closing tags which you can then exclude.
[edit]
This is probably better for your purpose:
(?<=(<title>))[^<]+
That should match anything in between two title tags.
[edit 2] This also works in case there are different tags inside the tag you're searching:
(?<=(<title>)).*(?=</title>)
