How to enable a filter with regular expression with DXL

Hi folks,

I'm trying to write some DXL code to view the objects after applying with filters in current module. The filter contains regular expression. I searched in DXL manual and found a function: Filter contains(attribute(string attributeName)), string text, [bool caseSensitive, bool useRegExp]), there is also a sample
+Module m = current
Filter f = contains(attribute "Object Text", "shall", false)
set f
filtering on+
But I had no idea how to use regular expression.

For example, if I only hope to view the objects, which object heading attribute contains test+a-zA-Z (+a-zA-Z is a regular expression), how can I write the DXL code?

Thanks & Regards
Edward

Sorry for a wrong description.

I want to view the objects that the object heading attribute contains 'test' +[a-zA-Z](+[a-zA-Z] is a regular expression)

The reqular expression is a string which you use in the contains filtering as any other string

Module m = current 
string txt = "test+[a-zA-Z]" 
Filter f = contains(attribute "Object Heading", txt, false, true) 
set f 
filtering on

Thanks very much for the quick reply and sample code.
