Regular expression to find and replace a string in a xml

Question

I'm looking for one regular expression that could match a string for three specific cases in a xml file:

1. : Double-quotes surrounding a string.
   
2. : A string surrounded by the characters greater than and Less Than.
   
3. : A string surrounded by the characters ; and &.

Example:

• "MyString" - Valid match
• >MyString< - Valid match
• ;MyString& - Valid match

Other possible combinations are invalid match.

"MyString< - Invalid match

;MyString" - Invalid match

Answer 1

You cannot use regex to parse xml, it is not a regular grammar. Use an xml parser, seriously.

When you're using your parser to inspect text node values then and only then you might want to use (\".*?\")|(>.*?<)|(;.*?&) but I doubt you'll find the problem is framed the same way. >MyString< is very suspicious.

Answer 2

Try this: ("MyString")|(>MyString<)|(;MyString&)
