I'm trying to highlight (with <mark) a search string inside another string, but it shouldn't be part of a tag (i.e. te in <cite> shouldn't match, but te in test should). I've been using code like this to replace the match with the second regex listed, but that only works nestted.
我试图突出显示(使用 中的te不应该匹配，但是test中的te应该匹配)。我一直在使用这样的代码来替换列出的第二个regex，但这只适用于nestted。 )另一个字符串中的搜索字符串，但它不应该是标记的一部分(例如，
someElement.innerHTML.replace(regex, function(full, before, match, after) {
return before + '<mark>' + match + '</mark>' + after;
});
Suggestions I tried:
建议我尝试:
-
<\/\w*>(\w*\s*)*(te)(\w*\s*)*<([a-z]*\s*\w*="\w*")*>(doesn't match at all?) - < \ / \ w * >(\ w * \ s *)*(te)(\ w * \ s *)* <([a - z]* \ s * \ w * = \ w *)* >(不匹配?)
-
(<.+?>[^<>]*?.*)(te)(.*[^<>]*?<.+?>)(only works on the nested tags) - (< + ? >[^ < >]* ?。*)(te)(。*[^ < >]* ? < + ? >)(只适用在嵌套标签)
-
((<.+?>[^<>]*?)?.*)(te)(.*([^<>]*?<.+?>)?)(.replacegives undefined's) - (< + ? >[^ < >]* ?)?。*)(te)(。*((^ < >]* ? < + ? >)吗?)(。取代了未定义的)
Example:
例子:
String to wrap: te
字符串包装:te
Input text:
输入文本:
‘This is a test string’
<cite> — some test wrapped too</cite>
Expected output:
预期的输出:
‘This is a <mark>te</mark>st string’
<cite> — some <mark>te</mark>st wrapped too</cite>
I've browsed a lot of "duplicates", but couldn't find an exact one, but if someone can lead me to a working example, that'd be lovely too, thanks!
我浏览了很多“复制品”，但是找不到一个确切的复制品，但是如果有人能给我一个工作的例子，那也太好了，谢谢!
An answer that's now deleted which worked the best for me is (te)(?![^<]*>) (by revo). This does however not work if the next char is >, but I'll see that as a unsolved edge case.
答案现在删除它的最好的工作了我(te)(? ![^ <]* >))(通过。但是，如果下一个char是>，那么这将不起作用，但是我将把它视为一个未解决的边缘情况。

Regex:
正则表达式:
(te)(?!\w*>)
It benefits from a negative lookahead to check if it is within an opening / closing tag or not. (?!\w*>) this will ignore any te that is followed by any word characters and > (which possibly denotes being within a tag name.)
它可以从消极的前视中获益，检查它是否在开始/结束标记中。(?!\w*>)这将忽略后面跟着任何单词字符和>的任何te(可能表示在标记名内)。
Failing case:
When there is potentially a string like test> (unpaired) within input string even though it is not a tag it doesn't match.
当输入字符串中可能有一个字符串，比如test>(未配对)，即使它不是一个标记，它也不匹配。
