regex - 正则表达式搜索“/”、“<”和“>”等字符

Question

如果我的文本包含“\ / > <”等字符并且我想找到它们，那么正则表达式模式应该是什么。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Super Kings从字符串中查找<span>Super Kings</span>，使用 VB 2010。

谢谢！

试试这个：

\bYour_Keyword_to_find\b

\b在 RegEx 中用于匹配单词边界。

你可能正在寻找这个：

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

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 “&lt;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 “&lt;>” «[^<>]+?»
      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 “&lt;/span>” literally «</span>»

在正则表达式中，您必须转义/with \。

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