Question

I am trying to take a string that has HTML, strip out some tags (img, object) and all other HTML tags, strip out their attributes. For example:

<div id="someId" style="color: #000000">
   <p class="someClass">Some Text</p>
   <img src="images/someimage.jpg" alt="" />
   <a href="somelink.html">Some Link Text</a>
</div>

Would become:

<div>
   <p>Some Text</p>
   Some Link Text
</div>

I am trying:

string.replaceAll("<\/?[img|object](\s\w+(\=\".*\")?)*\>", ""); //REMOVE img/object

I am not sure how to strip all attributes inside a tag though.

Any help would be appreciated.

Thanks.

Answer 1

You can remove all attributes like this:

string.replaceAll("(<\\w+)[^>]*(>)", "$1$2");

This expression matches an opening tag, but captures only its header <div and the closing > as groups 1 and 2. replaceAll uses references to these groups to join them back in the output as $1$2. This cuts out the attributes in the middle of the tag.
