Removing text between <LI> tags

[jwhite68]

Can anyone recommend how I can remove any text that lies between the <LI> tags. eg if its :

 

<LI class=MsoNormal style="BACKGROUND: white; MARGIN: 0cm 0cm 0pt; COLOR: black; tab-stops: list 36.0pt; mso-list: l0 level1 lfo1; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto">

 

I want to strip out everything to leave only <LI>.  I assume something like preg_replace, but can anyone advise how?

<pre>
<?php
$str = '<UL><LI class=MsoNormal style="BACKGROUND: white; MARGIN: 0cm 0cm 0pt; COLOR: black; tab-stops: list 36.0pt; mso-list: l0 level1 lfo1; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto">Text</LI></UL>';
echo preg_replace('/<(li)[^>]*>/i', '<\1>', $str);
?>
</pre>

Can you explain to me what the '<\1>' does in one of the arguments. I dont understand the presence of '1'.

The source text I have (from a client) seems to miss the end </LI> tags. Heres part of it.  I tried your code, but it doesnt strip the other tags within the LI tag:

 

<UL type=disc>
<LI class=MsoNormal style="BACKGROUND: white; MARGIN: 0cm 0cm 0pt; COLOR: black; tab-stops: list 36.0pt; mso-list: l0 level1 lfo1; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"><SPAN lang=EN-US style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-ansi-language: EN-US; mso-bidi-font-size: 8.5pt">1x 1 Sudio apartment</SPAN><SPAN style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 8.5pt"><o:p></o:p></SPAN> 
<LI class=MsoNormal style="BACKGROUND: white; MARGIN: 0cm 0cm 0pt; COLOR: black; tab-stops: list 36.0pt; mso-list: l0 level1 lfo1; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto"><SPAN style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 8.5pt">1</SPAN><SPAN lang=EN-US style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-ansi-language: EN-US; mso-bidi-font-size: 8.5pt">2</SPAN><SPAN style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 8.5pt"> x 2 Double bedroom apartments<o:p></o:p></SPAN></LI></UL> 

 

All I want to keep is the text content within LI tags.  not any of the class, style etc attributes.

That is a backreference.

You didn't specify this. To better approach this, are there any attributes that you want to allow and if so, in which tags?

[jwhite68]

No, I dont want to allow any attributes at all. Sorry that I wasnt clear in my original posting.
