jquery regexp - HTML tag from string

Question

how can I separate a HTML table tag from string by using regular expression?

var sTabString =' ... <table > <table ... any string ... id="Unique_1"  ... any string ...> abc def <table > ... ';
var sReg = '< *table .* id *= *"Unique_1" .*>';
var sRegEx = new RegExp(sReg);
var sResult = sTabString .match(sRegEx);
alert(sResult);

I expect the open tag with all its attributes as follows:

<table ... any string ... id="Unique_1"  ... any string ...>

I agree with @h2ooooooo - I wanted to link XY problem as well. Tell us what are you trying to achieve, because we are 98% sure you're not going to need regex for your task. — ElmoVanKielmo

@ElmoVanKielmo I changed it to that as it was confusing. As far as I can understand given the string <table id="foo" class="table-bordered"><thead><tr><th>Hi</th></tr></thead></table> he wants <table id="foo" class="table-bordered"> (the open tag). — h2ooooooo

can you post the full table code and tell us what you want to be extracted ? — aelor

This will get you every <table> element (and all its attributes) in a string.

var regex = new RegExp("<table.*?>", "g");

var result = str.match(regex);  

for (var i=0; i<result.length; i++)
{
    // do something with your <table> elements here
    console.log(result[i]);
}
