How to check if string is a valid XML element name?
- by xsaero00
I need a regex or a function in PHP that will validate a string to be a good XML element name.
Form w3schools:
XML elements must follow these naming
rules:
Names can contain letters, numbers, and other characters
Names cannot start with a number or punctuation character
Names cannot start with the letters xml (or XML, or Xml, etc)
Names cannot contain spaces
I can write a basic regex that will check for rules 1,2 and 4, but it won't account for all punctuation allowed and won't account for 3rd rule
\w[\w0-9-]
