Extracting the content within HTML tags using regular expressions

There is a specific string structure that needs to be processed:

<div class="myClass">
   Some Text.
</div> 
<div class="otherClass">
   Some Text.
</div>

The task at hand involves parsing the div with myClass and replacing certain text within it (specifically, replacing Text. with Content.)

Is it possible to achieve this using regex? It's important to note that only the content of the targeted div should be replaced, not all divs in general.

Your assistance on this matter would be greatly appreciated.

Answer №1

Avoid the use of regular expressions.

// Utilize DOM manipulation to parse HTML content
// and perform replacements without regex
var tempElement = document.createElement("div");
tempElement.innerHTML = 
    '<div class="myClass">\
       Some Text.\
    </div> \
    <div class="otherClass">\
       Some Text.\
    </div>';

// Collect elements with the same class in an array
// for reusability purposes
var elements = [];
for (var i = 0, l = tempElement.children.length; i < l; i++){
  var el = tempElement.children[i];
  if (el.className === 'myClass')
    elements.push(el);
}

// Perform a replacement operation on each element's content
// within the stored array
for (var i = 0, l = elements.length; i < l; i++){
  var el = elements[i];
  el.innerHTML = el.innerHTML.replace('Text', 'Content');
}

// Display the modified content
document.write(tempElement.innerHTML);
