StringRegExp

13 posts in this topic

I made the following code:

$String="<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"

$String=StringReplace($String,"</td><td class=char>",chr(32) & "(",0)
$String=StringReplace($String,"</td><td class=nm>",")" & chr(32) & "/" & chr(32),0)
$String=StringReplace($String,"<td class=nm>","",0)
$String=StringReplace($String,"</td>",")",0)
$String=StringStripWS($String,7)

Msgbox(0,"Cast","*" & $String & "*")

This code works good, but I'm not happy with it.

I'm not an expert for regular expressions.

Is it possible make a shorter code with the StringRegExp function?

Please help me.

You're doing 4 different things to each of those (4 different replacement values), you're safer doing what you are doing (but yes, it's possible).... you could split it up the same way with StringRegExpReplace() the same way as you have with StringReplace() and you'll find a speed increase.

Please help me.

Use the following example from the StringRegExp example in Help.

;Option 2, single return, php/preg_match() style
$array = StringRegExp('<test>a</test> <test>b</test> <test>c</Test>', '<(?i)test>(.*?)</(?i)test>', 2)
for $i = 0 to UBound($array) - 1
    msgbox(0, "RegExp Test with Option 2 - " & $i, $array[$i])
Next

If you still can't get it let us know. :)

I think this may be along the lines of what you are looking for.

$String = "<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"
$nOffset = 1
$Cast = ""
While 1
    $Name = StringRegExp($String, "<td class=nm>(.*?)</td>", 1, $nOffset)
    If @error = 0 Then
        $nOffset = @extended
    Else
        ExitLoop
    EndIf
    $Char = StringRegExp($String, "<td class=char>(.*?)</td>", 1, $nOffset)
    If @error = 0 Then
        $nOffset = @extended
    Else
        ExitLoop
    EndIf
    If $Cast <> "" Then $Cast = $Cast & " / "
    $Cast = $Cast & $Name[0] & " (" & $Char[0] & ")"
WEnd
MsgBox(0, "Cast", "*" & $Cast & "*")

Another possibility you could try is:

#include <String.au3>
Dim $aArray1[1], $cast

$String="<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"

$String = StringReplace ( $String, "<td class=char>", "<td class=nm>")
$aArray1 = _StringBetween($String, '<td class=nm>', '</td>')

For $i = 0 to UBound($aArray1, 1) -1
    $cast &= $aArray1[$i] & ", "
Next
$cast = StringTrimRight($cast, 2)

Msgbox(0,"Cast 0","* " & $cast & " *")oÝ÷ Ù8^­íý²;¬¶Ê&j|°k+-¢É"Øb±.r¥uëÞZ()í¢Ø^ F®Ýû§rبȧqëajܱ׬    ÞvÚ)ºYbú+«b¢wë¢f°yºZæÄv+lêi³}÷ß

So many ways is right... if you're just trying to use StringRegExp as everyone here is demonstrating... you could also do something like this:

$String="<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"
Dim $sHold = "*", $aArray
$aArray = StringRegExp($String, "(?s)(?i)\<td class.*?>(.*?)\<", 3)
For $iCC = 0 To UBound($aArray) - 1 Step 2
    $sHold &= $aArray[$iCC] & " (" & $aArray[$iCC+1] & " ) / "
Next
$sHold = StringTrimRight($sHold, 2) & "*"
MsgBox(0,0, $sHold)

But unless you want to get into the complication (I for one don't feel like trying to figure it out personally) of back tracking through StringRegExpReplace(), I still like the way you did it originally.

Edit:

Had to fix something...

Puh, I just managed it. This an another alternative:

Dim $Array_1
Dim $Array_2
Dim $Cast
Dim $CastList

$String="<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"

$Array_1=StringRegExp($String,'<td class=nm>(.*?)</td>',3)
$Array_2=StringRegExp($String,'<td class=char>(.*?)</td>',3)
for $i=0 to UBound($Array_1)-1
    $Cast=$Array_1[$i] & chr(32) & "(" & $Array_2[$i] & ")" & chr(32) & "/" & chr(32)
    $CastList=$CastList & $Cast
Next
$CastList=StringTrimRight($CastList,3)
MsgBox(0,"Cast List","*" & $CastList & "*")

Yes, this a complex code :)

I thank you for your help!

Glad we were able to help and you got it working! Your last option has some stuff that's not necessary imo. You'll notice that in your particular case StringBetween and StringRegExp are doing the same thing. I took my earlier code and replaced oe for the other for illustration.

Dim $Array1, $Array2, $Cast

$String="<td class=nm>Sigourney Weaver</td><td class=char>Ellen Ripley</td><td class=nm>Carrie Henn</td><td class=char>Rebecca 'Newt' Jorden</td><td class=nm>Michael Biehn</td><td class=char>Cpl. Dwayne Hicks</td>"

$Array1 = StringRegExp($String,'<td class=nm>(.*?)</td>',3)
$Array2 = StringRegExp($String,'<td class=char>(.*?)</td>',3)

For $i = 0 to UBound($Array1, 1) -1
    $Cast &= $Array1[$i] & " (" & $Array2[$i] & ") / "
Next

$Cast = StringTrimRight($Cast, 4)
MsgBox(0,"Cast List","* " & $Cast & " *")

Both of you need to learn about escape characters... from looking at your examples.

Both of you need to learn about escape characters... from looking at your examples.

Escape Characters: a single character which in a sequence of characters signifies that what is to follow takes an alternative interpretation.

I guess you're suggesting that we learn about the character sets that begin with "\" in order to shorter the StringRegExp lines. Well I've tried several combination of these escape character sets individually and together and can't figure out the right ones to i) produce the same result and ii) shorten the following lines. Granted they could be useful in shortening the pattern, however to a noob they can be quite cryptic and less focused allowing room for possible false positives.

$Array_1 = StringRegExp($String,'<td class=nm>(.*?)</td>',3)
$Array_2 = StringRegExp($String,'<td class=char>(.*?)</td>',3)

On the other hand if I've totally missed what you were suggestion, can you explain with an example. Thanks again for the edumakation!

\<\td class

should be

\<td class

\t is for "tab"
