RegEx for capturing an attribute value in a HTML element

Question

I have a problem to extract text in the html tag using regex.

I want to extract the text from the following html code.

<a href="http://google.com/" target="_self" title="TEXTDATA" class="encyclopedia">Google</a>

The result:

TEXTDATA

I want to extract only the text TEXTDATA

I have tried but I have not succeeded.

Answer 1

Here we want to swipe the string up to a left boundary, then collect our desired data, then continue swiping to the end of string, if we like:

<.+title="(.+?)"(.*)

const regex = /<.+title="(.+?)"(.*)/gm;
const str = `<a href="http://google.com/" target="_self" title="TEXTDATA" class="encyclopedia">Google</a>`;
const subst = `$1`;

// The substituted value will be contained in the result variable
const result = str.replace(regex, subst);

console.log('Substitution result: ', result);

RegEx

If this expression wasn't desired, it can be modified or changed in regex101.com.

RegEx Circuit

jex.im also helps to visualize the expressions.

PHP

$re = '/<.+title="(.+?)"(.*)/m';
$str = '<a href="http://google.com/" target="_self" title="TEXTDATA" class="encyclopedia">Google</a>';
$subst = '$1';

$result = preg_replace($re, $subst, $str);

echo $result;

Use this regex:

title=\"([^\"]*)\"
