正则表达式在特定单词后查找 href

Question

<a href="">ABCD</a>
<a href="text1">ABCD</a>
<a href="text2">ABCD</a>

I need js regex to find first href after "ABCD", "text1" not "text2".

Answer 1

You are not very specific but this

>\w+<[^h]*href="([^"]*)"

should be close to what you are looking for.

Note: You want to get not the whole match but the first capture group.

Answer 2

At the suggestion of @G0dsquad I have posted a formal answer. The regex pattern I used below is:

^.*?ABCD.*?href="(.*?)".*$

 var input = "<a href=\\"\\">ABCD</a><a href=\\"text1\\">ABCD</a><a href=\\"text2\\">ABCD</a>"; var regex = /^.*?ABCD.*?href="(.*?)".*$/g; var match = regex.exec(input); console.log(match[1]);

Note that I stripped away the line breaks in the input to cram everything into a single line. But adding newline characters should not change the behavior of the regex. Also note that Regex101, while a very useful tool, appears to apply the regex to each individual line, which will not be your use case.
