I've tags in string like [note]some text[/note] where I want to extract the inside text between the tags.
Sample Text:
Want to extract data [note]This is the text I want to extract[/note]
but this is not only tag [note]Another text I want to [text:sample]
extract[/note]. Can you do it?
From the given text, extract following:
This is the text I want to extract
Another text I want to [text:sample] extract
We can try matching using the following regex pattern:
\[note\]([\s\S]*?)\[\/note\]
This says to just capture whatever comes in between [note] and the closest closing [/note] tag. Note that we use [\s\S]* to potentially match desired content across newlines, should that be necessary.
var re = /\[note\]([\s\S]*?)\[\/note\]/g;
var s = 'Want to extract data [note]This is the text I want to extract[/note]\nbut this is not only tag [note]Another text I want to [text:sample]\n extract[/note]. Can you do it?';
var m;
do {
m = re.exec(s);
if (m) {
console.log(m[1]);
}
} while (m);
I wrote this while Tim posted his answer and it's quite like but I figured I'll post it anyway since it's extracted to a re-usable function you can use for any tag.
const str = `Want to extract data [note]This is the text I want to extract[/note]
but this is not only tag [note]Another text I want to [text:sample]
extract[/note]. Can you do it?`;
function extractTagContent(tag, str) {
const re = new RegExp(`\\[${tag}\\](.*?)\\[\\/${tag}\\]`, "igs");
const matches = [];
let found;
while ((found = re.exec(str)) !== null) {
matches.push(found[1]);
}
return matches;
}
const content = extractTagContent("note", str);
// content now has:
// ['This is the text I want to extract', 'Another text I want to [text:sample] extract. Can you do it?']
