How Can I Efficiently Remove Attributes from HTML Tags Using Regular Expressions?

Removing Attributes from HTML Tags

In the realm of web development, working with HTML can often require manipulating its tags and their attributes. One common task is removing attributes to achieve desired effects.

Consider the following HTML code:

<p></p>

To remove all attributes from these tags, leaving just their content, one can employ a regular expression approach:

$text = '<p></p>

This regular expression breaks down as follows:

/              # Start Pattern
]*?        # Match anything other than '>', Zero or More times, not-greedy (wont eat the /)
(\/?)         # Capture Group  - '/' if it is there
>             # Match '>'
/is            # End Pattern - Case Insensitive & Multi-line ability

By applying the replacement text of to the matched text, it strips any attributes following the tag name.

<p>
  <strong></strong>hello
</p>

While this solution can effectively remove attributes, it's important to note that it may not handle all possible input scenarios perfectly. For a more comprehensive attribute filtering approach, consider using libraries like Zend_Filter_StripTags, which provides a more robust solution for handling various input cases.
