The TalendString routine contains several functions which allow you to carry out various operations on alphanumerical expressions.

You can access these functions by double-clicking the TalendString node under the system routines folder in the Repository tree view.

Syntax
AddEscapeChars Adds a specified character before each special character (that is, a character that is not a letter, a digit, _, or space) in a string. TalendString.addEscapeChars("padding chars",'escape char')

replaceSpecialCharForXML

returns a string from which the special characters (eg.:: <, >, &...) have been replaced by equivalent XML characters.

TalendString.replaceSpecialCharForXML("string containing the special characters - eg.: Thelma & Louise")
