How to capture HTTP headers properly?

  • L

    What's the best way to capture HTTP <h1> or <h2> headers?
    I mean something like this:

    <h2>Bandwidth Usage</h2>
<span>
0 GB /
Unlimited</span>

    Doing an LR includes <span> in the capture as well (I know I can replace it in a Function block, but that's too many unnecessary blocks). So what's the most efficient way to capture this?

    regex or you can use css

    Can you please provide an example?

    I've done something like this before with CSS:

    Selector: [name=token]
Attribute: value

    But I don't know how to use it in this case.

    im not an expert with regex or css i would need the complete source code to trial and error 😄

    Well, I've provided an example in my first post. How would you capture that?

    if done in regex you could use <h2>Bandwidth Usage<\/h2>\n<span>\n(.*\n.*)<\/span> and group 1 should capture it but css is easier in chrome you can just copy innerHTML or outerHTML depending what you need

    @cass
    I want to capture what is inside <span> like so:
    x GB / Unlimited
    How would I use CSS here? What should I exactly use for Selector and Attribute?

    Open it with chrome, right click inspect element, highlight the span element you want to capture and right click -> copy -> selector. Paste it in OB and as attribute to capture you can put innerHTML. This procedure works in 90% of cases.

    Thank you so much. It's much better now, however I get something like this:
    x GB /
    Unlimited
    Is it possible to get rid of the unnecessary line break?

    Function block -> Replace -> Maybe Tick regex idk -> Replace \r\n or \n with nothing (see which one works)

    Regexing \n works perfectly.
    I was trying to figure out a way to do it in a single block of parsing. I see that there's an option to use regex in combination with LR but not CSS. Any particular reason for lack of regex in CSS mode?

    CSS Selector and Regex are 2 different ways of parsing stuff, so it makes no sense to do it in a single block... the only way to use a single block is to use regex from the beginning, but i don't have the time to write you the pattern now, and i would need the entire page source code anyways

    I know, but I was wondering maybe they could be used together like LR and regex to reduce the number of blocks. But I guess adding an extra Replace function won't use much resources.
    I wouldn't presume to bother you like that since I can write it with trial and error, besides I'm not looking for ready answers but directions. At any rate I was deliberately avoiding regex altogether since as you've stated in the other thread it's slow.
    I think I've achieved what I wanted with the things I've learned here. Thank you all.
