how to prevent Look-ahead and look-behind assertions have effect on the entire string Topic is solved

[rj8810]

@rj8810, could you post a concise description of what you are trying to match and what the rules of matching need to be? Preferably post the real haystack you are using, not the one with reds and yellows

ready, post a real case of what I need, in advance thanks to all

Try this:

Code: Select all

document =  href="222xxxhref="111xxxanything-xxx/div(id:123)">yyyy/div(id:222)">
keyword2 = anything

RegExMatch(document, "(href="")(.(?!(?1)|(?3)))*?.?(" . keyword2 . ")(?2)*?/div\(id:\d+\)"">", m)
MsgBox, % m

Try this:

Code: Select all

document =  href="222xxxhref="111xxxanything-xxx/div(id:123)">yyyy/div(id:222)">
keyword2 = anything

RegExMatch(document, "(href="")(.(?!(?1)|(?3)))*?.?(" . keyword2 . ")(?2)*?/div\(id:\d+\)"">", m)
MsgBox, % m

thank you very much, this code seems to work very well,

Code: Select all

q::
document =  href="222xxx href="111xxxanything-xxx/div(id:123)">yyyy/div(id:222)">thepatternrepeatshref="222xxxhref="333xxxanything-xxx/div(id:333)">yyyy/div(id:444)">...longtex...href="xxx
keyword2 = anything

p := 1
array := []
array2 := []
while p:=RegExMatch(document, "(href="")(.(?!(?1)|(?3)))*?.?(" . keyword2 . ")(?2)*?/div\(id:\d+\)"">", m, p+StrLen(m))
{
Array[A_Index] := m ;esto sólo recupera el patron	
Array2[A_Index] := m1 ;esto sólo recupera el subpatron
msgbox % "pattern number " . A_Index . " is " . Array[A_Index]
msgbox % "subpattern number " . A_Index . " is " . Array2[A_Index]
Count := Array.Count()
}
MsgBox, % Count
return

although I haven't been able to capture subpatterns just after href=" and just before ">.
try putting everything in the search= variable, since that way I don't have to escape many characters, and I put the famous capturing parentheses: (https://www.autohotkey.com/docs/misc/RegEx-QuickRef.htm#subpat) , but I did not make it

Code: Select all

q::
document =  href="222xxx href="111xxxanything-xxx/div(id:123)">yyyy/div(id:222)">thepatternrepeatshref="222xxxhref="333xxxanything-xxx/div(id:333)">yyyy/div(id:444)">...longtex...href="xxx
keyword2 = anything
search = (href="()(.(?!(?1)|(?3)))*?.?%keyword%(?2)*?/div\(id:\d+\))">

p := 1
array := []
array2 := []
while p:=RegExMatch(document, search, m, p+StrLen(m))	
{
Array[A_Index] := m ;esto sólo recupera el patron	
Array2[A_Index] := m1 ;esto sólo recupera el subpatron
msgbox % "pattern number " . A_Index . " is " . Array[A_Index]
msgbox % "subpattern number " . A_Index . " is " . Array2[A_Index]
Count := Array.Count()
}
MsgBox, % Count
return

neither this way: (href=""(subpattern)"">

Code: Select all

q::
document =  href="222xxx href="111xxxanything-xxx/div(id:123)">yyyy/div(id:222)">thepatternrepeatshref="222xxxhref="333xxxanything-xxx/div(id:333)">yyyy/div(id:444)">...longtex...href="xxx
keyword2 = anything

p := 1
array := []
array2 := []
while p:=RegExMatch(document, "(href=""()(.(?!(?1)|(?3)))*?.?(" . keyword2 . ")(?2)*?/div\(id:\d+\))"">", m, p+StrLen(m))	; Aquí lo que se busca es esto: href="/item/domiciliario-iid-1115341856">        pero  Para escapar de comillas literales hay que anteponer otra " En regex, O almacenar la cadena literal en una variable ya que las variedades asumen todo como literal excepto los caracteres especiales de regex lo cual es una buena solucion
{
Array[A_Index] := m ;esto sólo recupera el patron	
Array2[A_Index] := m1 ;esto sólo recupera el subpatron
msgbox % "pattern number " . A_Index . " is " . Array[A_Index]
msgbox % "subpattern number " . A_Index . " is " . Array2[A_Index]
Count := Array.Count()
}
MsgBox, % Count
return

any idea, it would be the last thing I ask to achieve the purpose of this post, thank you very much in advance

@rj8810, it seems you are trying to match html, yet your example isn't valid html... With your example I guess something like this would work: href="((?:.(?!href="))*?anything-(?:.(?!">))*?\/div\(id:\d.*?)">, whereas with real HTML this would probably be better: href="((?:.(?!">))*?anything-(?:.(?!">))*?\/div\(id:\d.*?)">

Thank you very much, I tried your first code in many scenarios and it always works perfectly.

the second doesn't work because it matches from the first "href" it finds in the html document to the last "">" it finds in the document, thus matching the entire document. the second code works, but strictly in html document without errors.it doesn't work in other scenarios, instead the first one is more universal, just what I was looking for, although I couldn't understand your code, because I think it's outside the autohotkey documentation, but well when I have time I'll investigate it, since I don't like it alone copy and paste, if not I like to understand why the code works:

Code: Select all

Q::
content = notvalifirstdhref="validfirsthref="/item/mykeyword-iid-1111111">second href="/item/mykeyword-iid-2222222">
keyword:="mykeyword"
search = href="((?:.(?!href="))*?%keyword%-(?:.(?!">))*?id-\d.*?)">
;search = href="((?:.(?!">))*?%keyword%-(?:.(?!">))*?id-\d.*?)">
p := 1
array := []
while p:= RegExMatch(content, search, StubPat, p+StrLen(StubPat))
{
Array[A_Index] := StubPat1 ;esto sólo recupera el subpatron
msgbox % "Element number " . A_Index . " is " . Array[A_Index]
Count := Array.Count()
}
msgbox, % "count =" Count
return

thanks for sharing your knowledge I spent many days reading.
Also many thanks to everyone else for their help:

The only way I find to thank you is also to share, if this could be useful to you or you have better ideas, I invite you to see this post, with which I achieved my complete purpose: web scraping with regexmatch in the cloud with autohotkey.ahk
