C#正则表达式,不包括字符串

Question

我有一个字符串的集合,我想要的正则表达式是收集所有开始与http ..

HREF = "http://www.test.com/cat/1-one_piece_episodes/的" href = "http://www.test.com/cat/2-movies_english_subbed/" HREF ="HTTP://www.test的.com /猫/ 3-english_dubbed/"HREF =" http://www.exclude.com"

这是我的正则表达式模式..

href="(.*?)[^#]"

并返回此

href="http://www.test.com/cat/1-one_piece_episodes/"
href="http://www.test.com/cat/2-movies_english_subbed/"
href="http://www.xxxx.com/cat/3-english_dubbed/"
href="http://www.exclude.com"

什么是排除最后一场比赛的模式..或排除具有排除域内的匹配,如href ="http://www.exclude.com"

编辑: 多次排除

href="((?:(?!"|\bexclude\b|\bxxxx\b).)*)[^#]"

Answer 1

@ridgerunner和我会将正则表达式更改为:

href="((?:(?!\bexclude\b)[^"])*)[^#]"

它匹配所有href属性,只要它们不结束#并且不包含该单词exclude.

说明:

href="     # Match href="
(          # Capture...
 (?:       # the following group:
  (?!      # Look ahead to check that the next part of the string isn't...
   \b      # the entire word
   exclude # exclude
   \b      # (\b are word boundary anchors)
  )        # End of lookahead
  [^"]     # If successful, match any character except for a quote
 )*        # Repeat as often as possible
)          # End of capturing group 1
[^#]"      # Match a non-# character and the closing quote.

允许多个"禁词":

href="((?:(?!\b(?:exclude|this|too)\b)[^"])*)[^#]"
