StringRegExp Help

5 posts in this topic

With StringRegExp from the beta verison. I have

created a basic xml tag parser. Unfortunately if

tags

using the following reg pattern

$pattern = "<(?i)"&$tag&">(.*?)</(?i)"&$tag&">"

against the following string

$stext = "<test>a</test> <test>b</test> <test>c</Test>"

result: a, b and c

if there is no space between the tags

$stext = "<test>a</test><test>b</test><test>c</Test>"

result: a

How can the regular expression pattern be changed to

get a result whether there is a space or not?

Any help is appreciated.

My goal is to create a simple function to read a simple xml

config file into an array. Without needing an external parser (.dll).

Func tagarray($tag, $stext)

  $pattern = "<(?i)"&$tag&">(.*?)</(?i)"&$tag&">"
  $resultarray = StringRegExp($stext,$pattern,3)
  
  $error = @error
  If @error = 0 and @extended = 1 Then
      return $resultarray
  Else
     ;msgbox(0,"error","@error = "& $error & @CRLF & "@extended = " & @extended)
      return 0
  EndIf
  return 
EndFunc

$stext = "<Test>a</test><test>b</test> <test>c</Test>"
$tag = "test"   
$resultarray = tagarray($tag, $stext)
For $i = 0 To UBound($resultarray) - 1
    MsgBox(0, "Result", $resultarray[$i])
Next

First nice code. I have never applied myself enough to completely understand StringRegExp

However I can get where ever i want with string controls

$test = "<Test>a</test><test>b</test> <test>c</Test>"

for $x = 1 to 1000
$L_loc = StringInStr($test, "</test>")

If @error then ExitLoop

$result = StringTrimLeft( $test, $L_loc -2)

$result_2 = StringLeft( $result, 1)

$result_3 = StringTrimLeft($result, 3)

$test = $result_3

If $result_2 <> "" Then
    MsgBox(0,"test", "final result = " & $result_2)
EndIf
Next

maybe this can help you

Thanks for sharing the alternative method.

I found a work around to the problem. Its seems like StringRegExp gets one

character ahead of itself. So with that in mind changing the pattern to the following works.

$pattern = "<(?i)"&$tag&">(.*?)</(?i)"&$tag

;removed the final &">"

$test = "<Test>a</test><test>b</test> <test>c</Test>" ;example search string

With this regular epression pattern it looks for "<test>c</test"

and that leaves the final ">" as an extra character and with

that extra character it finds all ocurrences of the tag.

It should not be dropping that last character (or picking up an extra, depending on your point of view). I will investigate and get back to you.

This is the result of a bug in StringRegExp. I will investigate this weekend and see if I can fix it for the next Beta distribution.
