Array - StringRegExp Returning a Blank Value

6 posts in this topic

Why does this give me a blank value in the array? Anyone know a workaround?

Here a example of the problem

#include <Array.au3>
Dim $Price
$source = '<span class="ebSold">£19.00</span><span class="ebEnded">£39.99</span>'
$Price = StringRegExp($source,'<span class="ebSold">£(.*?)</span>|<span class="ebEnded">£(.*?)</span>', 3)
_ArrayDisplay($Price,"Price")

Thanks,

Keith

You need to learn about escape characters:

#include <Array.au3>
Dim $Price
$source = '<span class="ebSold">£19.00</span><span class="ebEnded">£39.99</span>'
$Price = StringRegExp($source,'\<span class="ebSold"\>\£(.*?)\<\/span\>|\<span class="ebEnded"\>\£(.*?)\<\/span\>', 3)
_ArrayDisplay($Price,"Price")oÝ÷ ØGb´   m Øb²Þ©²j+zǧ±ëh殶­sb6æ6ÇVFRfÇC´'&æS2fwC°¤FÒb33cµ&6P¢b33c·6÷W&6RÒb33²fÇC·7â6Æ73ÒgV÷C¶V%6öÆBgV÷C²fwCº3ãfÇC²÷7âfwC²fÇC·7â6Æ73ÒgV÷C¶V$VæFVBgV÷C²fwCº33ãfÇC²÷7âfwC²b33°¢b33cµ&6RÒ7G&æu&VtWb33c·6÷W&6RÂb33²b3#²fÇC·7â6Æ73ÒgV÷C¶V"â³ògV÷C²b3#²fwC²b3#º2â£òb3#²fÇC²b3#²÷7âb3#²fwC²b33²Â2¥ô'&F7Æb33cµ&6RÂgV÷Cµ&6RgV÷C²

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

No workarounds needed. The problem is with your RegExp pattern. The function is working correctly you just need to tweak it so the "blank" isn't there. You're on the right path using the "|". Give it another shot, this stuff can be tricky! Remember that sometimes "less" is more. Simplify your pattern :)

$Price = StringRegExp($source,'\£(.*?)</span>|\£(.*?)</span>', 3)

Edit: SmOke_N... he's da man. I'd listen to him over me, that's for sure!!

Thanks a MILLION! :) SmOke_N

I have some other RegExp can you confirm that I understand correctly.

An escape character is a means that it will be taken as a literal character?

Would this be put on all character that aren't letter or digit?

So

ViewItem">([^<].*?)</a>
ViewItem"\>([^<].*?)\<\/a>

<td class="ebLower ebcBid">(.*?)</td>
\<td class="ebLower ebcBid\"\>(.*?)\<\/td\>

<span class="shpTxt">(.*?)</span>
\<span class="shpTxt"\>(.*?)\<\/span\>

<td class="ebLower ebcTim">(.*?)</td>
\<td class="ebLower ebcTim"\>(.*?)\<\/td\>

What is this?

ViewItem">([^<].*?)</a>
ViewItem"\>([^<].*?)\<\/a>
?

Also, you don't really need to escape right arrow... (I do it out of habit).

There is an image and a link linking to the same place so it doesn't detect <img tag

ViewItem"\>([^\<img].*?)\<\/a\>
