Informatica-替换目标中的字符

Question

Im working in a project which we create hundreds of xml's in informatica everyday, and all the data which is in the xml should be filtered, like removing all kind of special characters like * +.. You get the idea.

Adding regular expressions for every port is too complicated and not possible due the large amount of mapping we have.

I've added a custom property to the session XMLAnyTypeToString=Yes; and now i get some of the characters instead of &abcd, in their usual presentation (" + , ..).

I'm hoping for some custom property or change in XML target to remove these characters completely. any idea?

You can make use of String.replaceAll method:

  String replaceAll(String regex, String replacement) Replaces each substring of this string that matches the given regular expression with the given replacement. 

You can create a set of symbols you want to remove using regex, for example:

[*+"#$%&\(",.\)]

and then apply it to your string:

String myString = "this contains **symbols** like these $#%#$%";
String cleanedString = myString.replaceAll("[*+"#$%&]", "");

now you "cleanedString" is free of the symbols you've chosen.

By the way, you can test your regex expression in this excellent site: http://www.regexplanet.com/advanced/java/index.html
