StringRegExp and "Unterminated string" error

[shaqan]

Hello.

I have regular expression. But I cannot seem to accommodate with the AutoIT3, because regular expression itself is also containing multiple quotation marks and while trying to execute it, I would receive "Unterminated string" error messages for this row

Regular expression pattern itself (tested and seems to be doing what I want it to do)

  Quote

/<meta(?=[^>]*name="description")\s[^>]*content='([^>]*)"/sig

Expand  

Local $iOStr = StringRegExp($iContent, "/<meta(?=[^>]*name="description")\s[^>]*content='([^>]*)"/sig", 1,1)

How to fix this? I've tried adding apostrophes here and there and also / or \, does not seem to work out properly.

Local $iOStr = StringRegExp($iContent, '/<meta(?=[^>]*name="description")\s[^>]*content=''([^>]*)"/sig', 1,1)

Hmm. So what I should have been doing was surrounding the regex with apostrophes and adding one inside. Thanks. Much appreciated.

As a general rule, when your AutoIt string is delimited by one of ' or " you have to double significant ' or " (respectively).

It's smart to choose the delimiter (' or ") that will minimize the number of doublings, for best readability. Compare with:

Local $iOStr = StringRegExp($iContent, "/<meta(?=[^>]*name=""description"")\s[^>]*content='([^>]*)""/sig", 1,1)
