How to get exact match of a word

Recommended Posts

ur

When I am searching a word from a sentence through StringInStr, it is not giving exact match but it is giving the word if the letters in the word are included in it.

Ex: If I am searching for a word Sun in a sentence below.

Sun is hot today.   --> Here it is working as expected.

But it is returning a word exist even for below sentence also.

 even though it is sunday.

As sun is there in the word sunday.

How to exclude this and only it should return true when it finds the word sun.

StringInStr does a substring search, so you'd need to add a space after the word Sun to make sure it's looking for just Sun and not Sunday. Or use a StringRegEx instead.

Applying space is also a problem if the string required is at the end of statement.

Can you help on how to do it in regular expression.

ur,

You need to use the "word boundary" delimiters:

#include <MsgBoxConstants.au3>

Global $aText[2] = ["Sun is hot today", "even though it is sunday."]

For $i = 0 To 1
    $iRet = StringRegExp($aText[$i], "(?i)\b(sun)\b")
    $sFound = (($iRet = 1) ? ("Found") : ("Not found") )
    MsgBox($MB_SYSTEMMODAL, "Result", $sFound & " in:" & @CRLF &  $aText[$i])
Next

SRE decode:

(?i)    - Case insensitive
\b      - Start at a word boundary..
(sun)   - ..look for the 3 letters in order...
\b      - ...followed by another word boundary

"Today is sun"
Or if we remove 2nd \b in regex then it would fail in below case

"Today is sunday"

​This will work when the word ("sun") is at the end of the line. But it will not work for "sunday".

Are you sure about that? It seems to work fine for me:

#include <MsgBoxConstants.au3>

Global $aText[3] = ["Sun is hot today", "even though it is sunday.", "Hot is the sun"]

For $i = 0 To UBound($aText) - 1
    $iRet = StringRegExp($aText[$i], "(?i)\b(sun)\b")
    $sFound = (($iRet = 1) ? ("Found") : ("Not found") )
    MsgBox($MB_SYSTEMMODAL, "Result", $sFound & " in:" & @CRLF &  $aText[$i])
Next

Can we split a sentence by using the word exact match.

Ex: It should split the string only at sun it should not split at sun part of sunday.

$word="sun"

$element = " sun is hot on sunday morning "

$strSplittedString = StringSplit ( $element, $word,$STR_ENTIRESPLIT )

      Hi guys! I have these checkbox that I'm trying to click on. They have the same inner-text string but a different ID. Sometime there can be as many as 4 checkbox
      with the same string but the ID is always different. I tried a few methods down below but I'm unable to make any real results. Any suggestions or solutions I would
      appreciate it very much.
      <ul><li class="cx-list-item-wrapper" data-day="Aug 2 2018 07:27:37 GMT-0700 (Pacific Daylight Time)"><div class=""><div class="cx-list-item-container"><div class="cx-list-item cx-item-icon-2 pointer-cursor"><div class="cx-item-contents cx-item-time col-md-2"><!-- react-text: 675 -->Morning<!-- /react-text --><!-- react-text: 676 -->&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-1"><!-- react-text: 678 -->OTHER<!-- /react-text --><!-- react-text: 679 -- >&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-2"><!-- react-text: 681 -->8:30 AM<!-- /react-text --><!-- react-text: 682 -->&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-2"><!-- react-text: 684 -->10:30 AM<!-- /react-text --><!-- react-text: 685 -->&nbsp;<!-- /react-text -- ></div><div class="cx-item-contents col-md-1"><!-- react-text: 687 -->SRV<!-- /react-text --><!-- react-text: 688 -->&nbsp;<!-- /react-text --></div></div></div><div class="pull-right cx-listitem-chk"><div><input id="cx_checkbox1" class="cx-fa-chk cx-selfschedule-chk" value="on" type="checkbox"><label for="cx_checkbox1"></label></div></div></div></li><li class="cx-list-item-wrapper" data-day="Aug 2 2018 07:27:37 GMT-0700 (Pacific Daylight Time)"><div class=""><div class="cx-list-item-container"><div class="cx-list-item cx-item-icon-2 pointer-cursor"><div class="cx-item-contents cx-item-time col-md-1"><!-- react-text: 698 -- >Morning<!-- /react-text --><!-- react-text: 699 -->&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-1"><!-- react-text: 701 -->OTHER<!-- /react- text --><!-- react-text: 702 -->&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-2"><!-- react-text: 704 -->8:30 AM<!-- /react-text --><!-- react-text: 705 -->&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-2"><!-- react-text: 707 -->2:30 PM<!-- /react-text --><!-- react-text: 708 -- >&nbsp;<!-- /react-text --></div><div class="cx-item-contents col-md-1"><!-- react-text: 710 -->SRV<!-- /react-text --><!-- react-text: 711 -->&nbsp;<!-- /react-text --></div></div></div><div class="pull-right cx-listitem-chk"><div><input id="cx_checkbox2" class="cx-fa-chk cx-selfschedule-chk" value="on" type="checkbox"><label for="cx_checkbox2"></label></div></div></div></li></ul> I tried the _IETagNameGetCollection() but it only check the box but doesn't fire the event! And I'm unable to submit that without a click action.
      Func _Box1() $oInputs = _IETagNameGetCollection($oIE, "input") For $oInput In $oInputs If $oInput.id == "cx_checkbox1" Then $oInput.checked = true Next Sleep(10) ToolTip('box1') EndFunc ;==>_Box1 I also tried click by text.The boxes do get check by a click but the problem with that is it will select every box that has the same string. I'm allowed only to check 1 box selection at a time per day for the submit button to work.  Any preference to select only the second box and bypass the other?
      Func _Morning() For $a In _IETagNameGetCollection($oIE, "div") If StringInStr(_IEPropertyGet($a, "innerText"), "Morning") Then _IEAction($a, "click") EndIf Next Sleep(10) ToolTip('Morning selected') EndFunc ;==>Morning The last method I tried was _IEGetObjById(). It doesn't click or respond to the checkbox.
      Func _Click1() $oChk = _IEGetObjById($oIE, "cx_checkbox1") _IEAction($oChk, 'click') Sleep(20) ToolTip('box1') EndFunc ;==>_Click1

      Hey there!
       
      I've been developing a artificial intelligence.

      My first hard task was letting the A.I know when a sentence is found in memory with different words
      What i tried to do here is simply, get all the words in user sentence that could be used
      as a identifier
              
              example: Steve Jobs
              
              then identify the sentence purpose with the words we found in the past "for" loop
              
              example: Do/Know/You/Who/Steve/Jobs
              
              Compare the example in the following matching sentences in memory.
              
              1-Steve jobs was a known person
              2-Do you know who barack obama is?
              3-Do you know Steve jobs?
              4-Do you know who steve jobs is?
              5-How much money steve jobs had
              
              Then find the sentence that has way more matches than the other ones, remember that if the identifier words were not found
              (Steve jobs) then the sentence is invalid.
              
              Every sentence has a different answer and is important that the right one is chosen.
              
      If there's no more than the half of words in matches, then assign a variable the result of function, such as a return but for a global var.
      I couldn't figure out how to do that with StringRegExp.
       
      I honestly need help with detecting identifiers on memory sentences.
      I would also like to let the AI know typos, meaning that moeny and money means the same thing.
      Any help is hugely appreciated.

    • MrSparty1995
      By MrSparty1995
      I have a good handle on how to read a file line by line, and search for a given string.
      Basically using, FileOpen, FileReadLine, and StringInStr.
      I have been trying to figure out why my search keeps coming back with no match.
      For example, if my string line was "Where is Waldy", and I was searching for Waldy that comes back fine.
      But in my file, Let's say it is
      Where is "Waldy"
      So i read that line in and do a search for Waldy, but i comes back with no match since there is quotes around it.
      Is there a way to resolve this?
      Here is my actual example
      The line comes back like this
          <JposEntry logicalName="LineDisp_iSC480">
      I'm searching for LineDisp_iSC480, but its coming back with no match due to the quotes.
      Thanks in advance, James

      Hi guys
      I hope you can help me out with this one.
      I have a text file "test.txt" which could contain something like this:
      __________________________________________________________
      fiw
      eqw
      sdg
      xcv
      __________________________________________________________
      Each string has it's own line.
       
      I use this script to find a string in the text file.
      In this example, the string I am looking for is "iw".
      The string "fiw" makes it believe that "iw" is found in the file. How can I avoid this?
      I want it only to return EXACT results.
       
      $string = "iw" $File = FileOpen("test.txt", 0) $ReadFile = FileRead($File) FileClose($File) If StringRegExp(StringLower($ReadFile), StringLower($string)) Then MsgBox(0,"",$string & " is found in the file") Exit Else MsgBox(0,"",$string & " is not found in the file") Exit EndIf
