Question

I have code that iterates through a database using PHP, and processes the HTML to look like this:

First line etc<br />
Text blah blah blah blah, etc<br />
Moar text blah blah blah,<br />
<ul>
    <li>List Item 1</li>
    <li>List Item 2</li>
</ul>

However, I want the <br /> immediately before the <ul> removed. i.e.

...
Moar text blah blah blah,
<ul>
...

I cannot use CSS to correct this problem, as it is being parsed into a PDF format.

How do I go about removing the <br /> immediately before a <ul> (or <ol>)?

Thanks in advance

You can use regular expressions like this :

<?php

$text = 'First line etc<br />
Text blah blah blah blah, etc<br />
Moar text blah blah blah,<br />
<ul>
    <li>List Item 1</li>
    <li>List Item 2</li>
</ul>
';

$text = preg_replace('#<br\s*/>\s*<ul>#ims',"\n<ul>",$text);
