Removing Attributes from HTML Tags

<p>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.

<p>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 '<' at beginning of tags
(             # Start Capture Group  - Tag Name
 [a-z]        # Match 'a' through 'z'
 [a-z0-9]*    # Match 'a' through 'z' or '0' through '9' zero or more times
)             # End Capture Group
[^>]*?        # 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 &amp; Multi-line ability

<p>By applying the replacement text of <$1$2> to the matched text, it strips any attributes following the tag name.

  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.
