QTP的描述性编程与正则表达式

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
