HTML text extraction

Usually, a website gives preview of its articles by extracting some of the
first characters. This is easy if the article is a pure text, but what if
it's a HTML text? For instance, if I have the full text:

bla bla bla

• item 1


• item 2


• item 3

bla bla bla

• item
  
  As you can see, the tags are incomplete and it might break other texts below
  it (I mean, other than this preview). I need a way to solve this problem.

  You could do a couple of things:
  
  * Extract all the content and use strip_tags() to remove all the
  HTML markup. In the example you gave it might look a bit odd if
  the content suggests it was originally a list.
  * Access the extracted content through the DOM, and grab the
  textual content you need using node values. That way, you can
  limit it to a specific character count of content, and with a
  bit of work, you can preserve the original markup tags too

HI,

The easy way (Back to the Future 2 anyone...?) would be to use
strip_tags() first:

  You may want to try these HTML parser classes. They can parse (and even
  validate) HTML and return an array of tag or data elements. You can use
  it to pick the first tags and data you. Then you you the RewriteElement
  function to regenerate the HTML.
