Regex on Arrays

[NickD]

I am struggling to figure out how to use regex on arrays, the following script only successfully parses the first title, and then returns empty variables after that. There are 30 lines in both of the GetTag arrays.

If anybody could point me in the right direction it would be greatly appreciated.

Code: Select all

  // Titles
  IEGetTagsByAttrib>domain.com/,H3,ID=title,T,title

  // Video Links
  IEGetTagsByAttrib>domain.com,A,classname=youtube,O,url

  
  Let>k=1
  While>k<%title_Count%
  // Filter Title Array
  let>titlestring=title_%k%
  Let>pattern=.+?(?= \|)
  RegEx>pattern,titlestring,0,titlematches,num,0


  // Filter URL Array
  let>urlstring=url_%k%
  Let>pattern=^(https?\:\/\/)?(www\.youtube\.com|youtu\.?be)\/.+$
  RegEx>pattern,urlstring,0,urlmatches,num,0
  
  
  Let>title=titlematches_%k%
  Let>url=urlmatches_%k%
  Writeln>C:\Users\Shaolin Nick\Desktop\results.txt,res,%title%;%url%
  Let>k=k+1
  EndWhile
  

  GoSub>CloseIE

I sometimes concat the array into one string. Then I do the RegEx on that string.

I don't really follow why this isn't working. If your loop is working such that you have a different value for titlestring etc in each iteration then there's absolutely no reason why it wouldn't work.

It's got me miffed too Marcus...
When I loop through the array output by IEGetTags, ArrayVar_Count returns 30 for both titles and URLs.
All the titles and URLs are unique, they are pulled from 30 different divs on the same page, each containing a different video.

Could it be something to do with the way that the IEGetTagsByAttrib> arrays are structured? I know you can't use ARC> on them so was wondering if there were other limitations?

[Marcus Tettmar]

I've looped through arrays returned by IEGetTags... thousands of times.

Open IE, go to mjtnet.com and run this code:

Code: Select all

IEGetTagsByAttrib>mjtnet.com,DIV,classname=text,O,texts
Let>k=0
Repeat>k
  Let>k=k+1
  Let>this_text=texts_%k%
  MessageModal>this_text
Until>k=texts_count

Works fine.

So there's something else going on here. Are you able to send me some code which replicates the issue which I am able to run here?

Looping through the array output by IEGetTagsByAttrib> works fine in my script, the problem occurs when I try to parse it with regex. I will pm you the script, probably a newbie mistake in there somewhere

You aren't checking to see if there is a match. So even if there is no match you're outputting something like titles_3 or whatever. Maybe you just need to see if there's a match. Maybe if there's no match you want to assign the output to the input (i.e. the raw string prior to the RegEx - I don't know - you know what you want to do).
