[Devv]

Hi
im trying to find iframe tags in a string and append an empty line after them

Log(RegexReplace("(<iframe.*<\/iframe>)", "sometext<iframe-sometext-</iframe>sometext", "$1" & "<br>"))

Sub RegexReplace(Pattern As String, Text As String, Replacement As String) As String
  Dim m As Matcher
  m = Regex.Matcher(Pattern, Text)
  Dim r As Reflector
  r.Target = m
  Return r.RunMethod2("replaceAll", Replacement, "java.lang.String")
End Sub

the prevous code is logging

sometext<iframe-sometext-</iframe><br>sometext

but it should log

<iframe-sometext-</iframe>

it regex replace not working or im doing something worng ?

There're special characters that might be escaped ( look at https://www.b4x.com/android/forum/threads/tiny-regex-tip.63608/#post-419323)

You are doing something wrong.
If you only want to replace the text between the iframe elements then you should move the parenthesis to capture only that text.
