AW: How trim?

[Thomas Fischer]

Hi Bob,

this is a classical application of regular expressions. Try

get replaceText("        The cat sat under the mat.         ","^ *","")

The "^" tells the search engine to start at the beginning.
The "*" looks for as many of the previous characters (here space) as possible.

To get rid of them at the end use

get replaceText("        The cat sat under the mat.         "," *$","")

The "$" tells the search engine to look at the end.

All the best
Thomas
