php preg_replace html tags issue

Question

I have this html code.

 <P class=MsoNormal style='MARGIN: 0cm 0cm 10pt'><STRONG>text</P>
    <P class=MsoNormal style='MARGIN: 0cm 0cm 10pt'></P>
    <UL>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI>
    <LI>
    <DIV class=MsoNormal style='MARGIN: 0cm 0cm 10pt'>text</DIV></LI></UL>

I want remove style tag and its proprieties as well as class tag and its proprieties so the out would be :

  <P><STRONG>text</P>
    <P></P>
    <UL>
    <LI>
    <DIV>text</DIV></LI>
    <LI>
    <DIV>text</DIV></LI>
    <LI>
    <DIV>text</DIV></LI>
    <LI>
    <DIV>text</DIV></LI>
    <LI>
    <DIV>text</DIV></LI>
    <LI>
    <DIV>text</DIV></LI></UL>

Here is what i have tried but it is not working :

$html = preg_replace('/(]+) (style|class)=("|\').*?("|\'(>|\s))/img', '$1', $$html);

a) In what way is it not working? b) You can't parse HTML with regex stackoverflow.com/a/1732454/477127 — GordonM

try this:

$html = preg_replace("/(\s(class|style)[^>]+)/", "", $html);
