ignore hyperlinked text

unitechy · 10-30-2009, 06:23 PM

I have been working on some wp-plugin to practice php.
I have made a dictionary... which reads posts from wordpress post and the plugin converts difficult words stored in the a text file.
Now I don't want the plugin to read hyperlinked text. how do I achieve that? here is my code.

PHP Code:


			
if(stristr($the_content,$wordAndMeaning[0]) != false)

            {

                $the_content= str_replace($wordAndMeaning[0], "<acronym title=\"" . $wordAndMeaning[1] . "\">" . $wordAndMeaning[0] . "</acronym>", $the_content);

            }

You could use your function and then use a regular expression to remove all the <acronym> tags that appear inside <a> tags.

Here is a regular expression I have come up with. I have only tested it using a javascript regexp tester at http://www.regular-expressions.info/...ptexample.html

It should be the same for PHP though:

PHP Code:


			
$the_content = preg_replace('~(<a.*>)<acronym.*>(.*)</acronym>(</a>)~i', '$1$2$3', $the_content);

Let me know how you get on.

Your regexp is far too greedy, if there's multiple occurences, you might find that it strips them all out and everything in between. Something like the following (untested) may work;

php Code:

$the_content = preg_replace('#(<a[^href]+href[^>]+>)<acronym[^>]+>([^<]+)</acronym></a>#', '$1$2</a>', $the_content);

Your right. I've tried to work mine a little since when I tried yours on the javascript tester page it didn't work with the following information:

Regexp: (<a[^>]*>)?(<acronym[^>]*>(.*?)</acronym>)(</a>)?
Subject string: hey <a href="test"><acronym>yo</acronym> yo <acronym>bob</acronym></a> what's up? <a href="test">nothing</a>
Replacement text: $1$3$4

Code:

$the_content = preg_replace('~(<a[^>]*>)?(<acronym[^>]*>(.*?)</acronym>)(</a>)?~i', '$1$3$4', $the_content);

Let me know what you think.

Thank you very much for the replies. I have used the following code now.

Code:

while(!preg_match(<([A-Z][A-Z0-9]*)\b[^>]*>(.*?)</\1>,$the_content))
				{
				$the_content= str_replace($wordAndMeaning[0], "<acronym title=\"" . $wordAndMeaning[1] . "\">" . $wordAndMeaning[0] . "</acronym>", $the_content);
				}
