目标：将形如（tppabs="js_3.htm#window 窗口对象"）之类的问题替换成新的文字。
规则：以（tppabs="）开头，（"）结尾，中间有任意个字符
Java：^tppabs=".*"$
EditPlus(替换时注意选择"正则表达式")：^tppabs=".*"   如果末尾加美元符号($)，则不行！

 

Eclipse的正则表达式插件：Regular Expression Tester

Eclipse Regular Expression Tester

Features

• Test and search for regular expression
• Matches are colorized, for an easy visual clue
• Support for pattern flags (e.g. Pattern.DOTALL)
• LiveEval evaluates your regular expression while you are typing it, gives feedback on possible errors and shows any matches automatically
• LiveEval is supported for changes of the regular expression, the search text and the pattern flags
• 4 distinct match modes:
  • Find a sequence of characters
  • Match a complete text
  • Split text
  • Replace every occurence of the regex with a different string
    Replacing supports back references ($1,$2,...)
• LiveEval for match mode changes
• Context sensitive "Regular Expression Assist"
• Selective evaluation of expressions
• Bracket Matching
• Generation of string literals based on the regexp, e.g. "\(x\)" becomes "\\(x\\)"
• De-escape patterns in your code, e.g. \\(x\\) becomes \(x\)
• Improved "Clear Menu", choose which parts of the view you would like to get cleared every time you press the clear button
• Easy movement through matches: Choose "Previous Match" or "Next Match" and cycle through all matches found.
• Polished and accessible user interface, everything is reachable via keyboard
