CharacterData.substringData

Source:
JavaScript:
  var txt = document.createTextNode('AAA-BBB');
  var output = txt.substringData(2,3);
Output:
desired your browser
A-B


Remarks:
  • it seems that all relevant browsers support JavaScript try-catch statement therefore all examples are encapsulated with it (it avoids alert-popups)
  • thanks to White Space Handling in XML 1.0 specification default handling of white-spaces completely depends on XML application (note: WinIE do not preserve white-spaces by default while MacIE and Mozilla does)
  • during development tested with Mozilla night-builds, Netscape6, MicrosoftInternetExplorer5.5 and Opera5.02 on Windows2000
