在使用QTP描述性编程的方式进行脚本编写时，通常需要应用到正则表达式，relevantcodes.com的这篇文章《Descriptive Programming (DP) Concepts – 2 {Regular Expressions}》详细描述了正则表达式（尤其是通配符）在DP中的使用：

例如通配符的用法：
Browser("title:=Welcome: Mercury Tours").Page("title:=Welcome: Mercury Tours").Image("file name:=banner2.gif").Highlight
Browser("title:=Welcome: Mercury Tours").Page("title:=Welcome: Mercury Tours").Image("file name:=banner2.*").Highlight
Browser("title:=Welcome: Mercury Tours").Page("title:=Welcome: Mercury Tours").Image("file name:=banner.*").Highlight
Browser("title:=Welcome: Mercury Tours").Page("title:=Welcome: Mercury Tours").Image("file name:=ban.*gif").Highlight
Browser("title:=Welcome: Mercury Tours").Page("title:=Welcome: Mercury Tours").Image("file name:=ban.*f").Highlight
文中以Mercury Tours为例介绍了一些正则表达式的使用方法，例如：
' Using the first few characters of the title and the first few characters of the image
Browser("title:=Welc/w+/D+/w+").Page("title:=Welc/w+/D+/w+").Image("file name:=ban/w+/d+/./w+").Highlight
' Using the last few characters of the title with first and last characters of the image
Browser("title:=/w+/D+/w+ours").Page("title:=/w+/D+/w+ours").Image("file name:=b/w+2/.gif").Highlight
' Same as above for Browser and Page, but '...' for image
Browser("title:=/w+/D+/w+ours").Page("title:=/w+/D+/w+ours").Image("file name:=b/w+2/....").Highlight
' Same as above, but replaced 'b' with a '.'
Browser("title:=/w+/D+/w+ours").Page("title:=/w+/D+/w+ours").Image("file name:=./w+2/....").Highlight
