User input quotation marks problem

Recommended Posts

youtuber

if the user enters a double quotation marks in the input Friends

content="([^"]+)"
or

href='([^']+)'
How can I check if a single quotation marks is entered?

Could there be a problem when the user enters double or single quotation marks in the input field?
Or how can I read input in this case?

My sample codes

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Global $aListRegex = "<a href='https://www.autoitscript.com/forum/forum/2-autoit-general-help-and-support/'>" & @crlf & _
'<meta itemprop="url" content="https://www.autoitscript.com/forum/">'

$Form1 = GUICreate("Form1", 353, 393, 363, 59)
$aHtmLEdit = GUICtrlCreateEdit("", 8, 24, 321, 89)
GUICtrlSetData($aHtmLEdit, $aListRegex)
GUICtrlSetLimit($aHtmLEdit, 1000000)
$aRegexInput = GUICtrlCreateInput("", 40, 134, 305, 21)
GUICtrlSendMsg($aRegexInput, $EM_SETCUEBANNER, False, 'Please enter regex Sample : content="([^"]+)" ' & " Or " & "href='([^']+)'")
$Label1 = GUICtrlCreateLabel("Regex", 5, 136, 35, 17)
GUICtrlSetState($Label1,$GUI_FOCUS)
$aResultEdit = GUICtrlCreateEdit("" & @CRLF, 8, 176, 321, 137, BitOR($ES_MULTILINE, $ES_AUTOVSCROLL, $WS_VSCROLL))
GUICtrlSetData(-1, "")
GUICtrlSetLimit($aResultEdit, 1000000)
$RegexTest = GUICtrlCreateButton("RegexTest", 120, 344, 75, 25)

GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $RegexTest
$aReadRegexInput = GUICtrlRead($aRegexInput)
$aReadHtmLEdit = StringSplit(GUICtrlRead($aHtmLEdit), @CRLF, 1)
$aGetRegex = StringRegExp($aReadHtmLEdit, $aReadRegexInput,3)

For $i = 0 To UBound($aGetRegex) -1
GUICtrlSetData($aReadHtmLEdit, $aGetRegex[$i] & @CRLF, 1)
Next

    EndSwitch
WEnd

youtuber,

You can capture both of these links using a pattern like this...

#include <array.au3>

Global $sListbox = "<a href='https://www.autoitscript.com/forum/forum/2-autoit-general-help-and-support/'>" & @CRLF & _
        '<meta itemprop="url" content="https://www.autoitscript.com/forum/">'

$aResult = StringRegExp($sListbox, '(?i)(?:href=(?:\x22|\x27)|content=(?:\x22|\x27))([^\x22\x27]+)(?:\x22|\x27)', 3)

ConsoleWrite(@error & ' - ' & @extended & @CRLF)

_ArrayDisplay($aResult)

If you really want to test for ' or " just use hex notation, as above, or, stringinstr.

youtuber,

Then let me make a couple of suggestions:

1 - Use a dropdown list to let them select which pattern they want.  Eliminates typos and the need to determine which expression was selected.

2 - Use the defacto variable naming convention (a = array, s = string, etc).  These are documented somewhere, although where escapes me at the moment.

youtuber,
An expression written in an input to be used as a pattern doesn't need to be surrounded with quotes

; concept
$input = GUICtrlCreateInput(...)
$pattern = GUICtrlRead($input)
$result = StringRegExp($text, $pattern, 3)

But I agree with kylomas at 120% : it's highly better to suggest to the user a list of predefined expressions (combo, radio buttons, etc) so you don't have to check if the chosen pattern is valid or not  ;)
