Question

如果我的文字包含“\ /＆gt;＆lt;”这样的字符，那么正则表达式模式应该是什么？等等，我想找到它们。这是因为正则表达式将“/”视为搜索模式的一部分，而不是单个字符。

例如，我想使用VB 2010从字符串Super Kings中找到Super Kings。

谢谢！

Answer 1

试试这个：

\bYour_Keyword_to_find\b

在RegEx中使用

\b来匹配单词边界。

您可能正在寻找：

(?<=<span>)([^<>]+?)(?=</span>)

<强>解释

<!--
(?<=<span>)([^<>]+?)(?=</span>)

Options: case insensitive; ^ and $ match at line breaks

Assert that the regex below can be matched, with the match ending at this position (positive lookbehind) «(?<=<span>)»
   Match the characters “<span>” literally «<span>»
Match the regular expression below and capture its match into backreference number 1 «([^<>]+?)»
   Match a single character NOT present in the list “<>” «[^<>]+?»
      Between one and unlimited times, as few times as possible, expanding as needed (lazy) «+?»
Assert that the regex below can be matched, starting at this position (positive lookahead) «(?=</span>)»
   Match the characters “</span>” literally «</span>»

Answer 2

在正则表达式中，您必须使用/转义\。

例如，尝试： ~~(.*)<\/span>~~ ([^<]*)<\/span>或(.*?)<\/span>

正则表达式搜索“/”，“＆lt;”之类的字符和“＆gt;”
