AutoHotkey Community

I'm new to autohotkey. I'm trying to parse some information from an HTML file. What I want to do is that search through the URLs inside the file and find the first substring (with a known length) inside an URL after another particular substring. For example, say if an HTML file has the following URLs in it:

"http://abc.def/ghi"
"http://jkl.def/mno"

I'm looking for the first string after "def/", and that would be "ghi" in this case, after this is done, it will return "ghi" and terminate the loop. The length of both substring are known in advance. I'm a C programmer so I'm not very used to the syntax of autohotkey, especially the loops. I'm trying to parse each substring (with a length of 4 in my example) first inside every string, if it equals to the word I'm looking for, then return the next few characters after it (which in the example, has a length of 3), but I'm not sure how it is excatly done in autohotkey. Could anyone help me with this?

use
voundPos := RegExMatch("abcXYZ123", "abc(.*)123", SubPat) ; Returns 1 and stores "XYZ" in SubPat1

Read about Regex-Operations in the helpfile, they are very handy, formerly I used the normal string operations , but with Regexmatch all becomes easier

or use stringgetpos and then stringtrimleft

Thanks a lot for the help!

Now I'm getting an error every time I load the script saying it's missing a '('. This is what I have so far. I know that the word that I'm looking for ends with a quotation mark. Is there anything I did wrong here?

The problem is likely here:



The extra double quote makes it appear as if the RegEx Needle is still being defined, eliminate one of them and try it again. Also, the one true brace style is not supported in a file-reading loop so you may want to move the brace to the next line:

Thanks for the advice.

Now the script can be loaded, but more problems emerge. Every time when it run, it will say the variable that I'm reading contains illegal characters since I'm parsing HTML document. What should I do? Also, for RegExMatch, the string that I'm looking for is the word in the following URL:

<a href="http://www.abc.def/ghi=word">blah</a>

So the word is surrounded by an equal sign and a quotation mark. I used "ghi=" as the first keyword before (.*), but it seems that I can't use a quotation mark to end it. Is there any other way that I can handle this situation properly?

Remove %

Try this:



And if you're trying to capture a subpattern here:



Wouldn't you want to do this?

Thanks a lot!! It's working now!

I have a few other questions.

Is it possible to make Inputbox have multiple input field? I know I can use StringSplit and just let the user input everything in one field, but it just doesn't look very good.

So you have an html file, you want to find all strings between def/ and " . The following script will work.





Script is in biterscripting ( http://www.biterscripting.com ) . To try, save the script as C:/Scripts/def.txt, start biterscripting, enter the following command.




Make sure you enter the correct html file location in the script instead of "http://www.somesite.com/somepage.html". It can be a local file such as "C:/xyz.html" or a document on the internet such as "http://www.something.com/somepage.html". Double quotes are required in both cases. If on the internet, the beginning http:// is required. The extension does not matter - it can be a .txt file, .asp file, whatever. As long as the script finds instance of def/ in it, it will extract strings between def/ and ".

Hope this helps.

( There is also a sample script posted at http://www.biterscripting.com/SS_URLs.html . That extracts all URLs from a web page, if that's what you are trying to do. )

Jenni, I think you're in the wrong forum.

wwkuter1, since you've mentioned you're a C programmer, I suppose when you write \" you mean a literal " character. Perhaps you've figured it out already, but AutoHotkey uses ` as an escape character; except with double-quote marks, which must be doubled up to be interpreted literally in an expression:
\ has special meaning only in regular expressions, which are processed at a much later stage than ` or "".
It is not. However, it can easily be accomplished with AutoHotkey's GUI command/framework. A very basic example:
