Javascript Question

Are the angle brackets (< or >) special in a regular expression?

I am trying to get a regex expression to accept < and > as my outside delimiters to grab all the content in between them.

so content like such

< tfdsfa >


should be grabbed.

Do I have to escape the < and > characters or something?

Regex generated by my script:

/<[^(>)]*>/g


Code from file:

data.method.highlight = function() {
var x = data.syntax,
text = data.$.span.html();
for (var i=0, len = x.length; i < len; i++) {
var rx;
if (x[i].range) {
rx = new RegExp(x[i].tag[0] + "[^(" + x[i].tag[1] + ")]*" + x[i].tag[1], "g");
console.log(rx);
}
else {
var temprx = x[i].tag[0];
for (var z = 1; z < x[i].tag.length; z++) {
temprx += "|" + x[i].tag[z];
}
rx = new RegExp(temprx, "g");
}
text = text.replace(rx,function (match) {
console.log("looping - range");
return '<span class="' + x[i].class.default + '">' + match + '</span>';
});
data.$.span.html(text);
}
};

Answer

Neither < nor > are metacharacters inside a regular expression.

This works for me:

'<foo> and <bar>'.match(/<[^>]*>/g); // ["<foo>", "<bar>"]
