Confusion in RegExp

3 posts in this topic

Hello,

I am trying to create a regExp for following HTML text:
 

<a href="link=1">1</a> <b>2</b> <a href="link=3">3</a>  | <a href="link=2">Previous</a>  | <a href="link=3">Next</a>

My intention is to extract href from last <a> tag.
Here is my attempt:

Local $reg = '(?i)\|\s?<a href="(.*?)">Next</a>'
Local $text = '<a href="link=1">1</a> <b>2</b> <a href="link=3">3</a>  | <a href="link=2">Previous</a>  | <a href="link=3">Next</a>'
$aData = StringRegExp($text,$reg,3)
ConsoleWrite($aData[0]&@LF)

Now problem is i am unable to extract exact href from the last <a> tag.

Here is the output:
 

link=2">Previous</a>  | <a href="link=3

I know I can use other techniques, but i want to know, why my pattern is not working or what is the right pattern for such situation?

Thanks in Advance.

Something like this ?

Local $reg = '(?i).*<a\s+href="([^"]+)'
Local $text = '<a href="link=1">1</a> <b>2</b> <a href="link=3">3</a>  | <a href="link=2">Previous</a>  | <a href="link=3">Next</a>'
$aData = StringRegExp($text, $reg, 1)
ConsoleWrite($aData[0]&@LF)

      Well the plan is to use the power of regular expressions engine of AutoIT for patching binary data.
      Something like this: StringRegExp( $BinaryData,  "(?s)\x55\x8B.."
       
      <cut> ... Okay straight to question/problem
      ... certain bytes that are in the range from 0x80 to 0xA0 won't match.
      Hmm seem to be a char encoding problem. In detail these are 27 chars: 0x80, 0x82~8C, 0x8E, 0x91~9C, 0x9E,0x9F
      Here's a small code snippet to explore / explain this problem:
      #include "StringConstants.au3" $TestData = BinaryToString("0x7E7F808182") ;Okay $match = StringRegExp( $TestData ,'\x7E' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x7F' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x80' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x81' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x82' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;~ output: ;~ @extended = 2 $match = ;~ @extended = 3 $match = ;~ @extended = 0 $match = 1 ;~ @extended = 5 $match = ;~ @extended = 0 $match = 1 Hmm what to do? Go back and use the 'numberstring monster' implementation or just omit that range of 'unsafe bytes'. What is the root of this problem?
      Any idea how to fix this?
       
      Update: Okay I know a byte is not a character.
      But StringRegExp operates on String and so character level.
      Okay as long as you stay at Ansi encoding and only use /x00 - /X7F in the search pattern using  StringRegExp works well to search for binary data.
      What bytes can be matched that are in the range from /X7F - /xFF is also depending on the code page.
      So this avoid to search for bytes in the range from 0x80-0xa0 only applies to Germany.
      I just change this country setting:

      to Thai and now near all bytes from /X7F - /xFF fails to match.

      Hello,
      I have spent the past day fooling with StringRegExp to no avail attempting to get what would be a simple solution to an issue using StringRegExp.
      I will post the code in a sec. The string 'Java x Update y' where x and y are numeric values ONLY if a letter is mixed in anywhere then it should fail. I have been able to successfully deal with the x value so if x = 1234 or a1234 or 1a234 or 1234a would result in a fail if 'a' was in the string. However, when y = 1a234 then I get an output of 1 and when y = 1234a then the output = 1234 when both should fail. I am probably overlooking something simple and in looking through all the material and experimenting I am unable to figure it out and my experience with stringregexp and trying to find examples of this proved difficult. If someone could assist or point me to a thread ? Here is my code ; prob a simple fix. I am also trying to avoid white spaces.
      Thanks in advance

      Text in a file, read into var with fileread:
      <> <> <> <> < J please look > <> <> <> Hi, 
      I want  a RegExp to select around 'please', back to the previous < and forward to the next >.  I can select the line of text.  Then I add in (?s) and it selects the whole text.  I think I want to make it not greedy, (?U) , that seems to make it ungreedy after, but it still selects all the previous lines.
      $sPattern = "(?s)<.*please.*>" ; 1 $sPattern = "(?s)<(?U).*please.*>" ; 2 $sPattern = "(?s)<(?U).*please(?U).*>" ; 3 $sAry = StringRegExp($sHTML, $sPattern, 3)
