xsl apply templates condition
I am doing through php as my xslt processor is sablotron (It is
supported by php).

here are input and out put.
input html.
<html>
<head>
<meta name="generator" content="HTML Tidy, see www.w3.org" />
<title>HELLO LIST</title>
</head>
<body bgcolor="#C4C4C4" text="#443481" link="#1111EE">
<p>This is for br tag</p>
<div>The stylesheet is doing some mischief</div>
<div><font size="+1">WHAT IS THE REASON ?</font></div>
<br /><br /><br /><br /><br /><br />
<p>Is it not the proper syntax for matching<br />tag.</p>
<br />
<br />
</body>
</html>

xsl is.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="/">
<wml>
<card title="output">
<xsl:apply-templates/>
</card>
</wml>
</xsl:template>
<xsl:template match="head"/>
<xsl:template match="body">
<xsl:apply-templates/>
</xsl:template>

<xsl:template match="p/div | div/div | center/div | font/div">
<xsl:apply-templates/>
</xsl:template>
   
<xsl:template match="div">
<p><xsl:apply-templates/></p>
</xsl:template>

<xsl:template match="font/p | center/p | div/p | p/p">
<xsl:apply-templates/>
</xsl:template>     
      
<xsl:template match="p">
<p><xsl:apply-templates/></p>
</xsl:template>

<xsl:template match="p/font | center/font | div/font | font/font">
<xsl:apply-templates/>
</xsl:template>     

<xsl:template match="font">
<p><xsl:apply-templates/></p>
</xsl:template>

<xsl:template match="font/br | div/br | center/br | p/br ">
<br/>
</xsl:template>

<xsl:template match="body/text()">
<p><xsl:apply-templates/></p>
</xsl:template>

</xsl:stylesheet>

and the output is

<?xml version="1.0"?><!DOCTYPE wml PUBLIC '-//WAPFORUM//DTD WML
1.2//EN'
  'http://www.wapforum.org/DTD/wml_1.2.xml'><wml><card title="wml
  output">

<p>
</p><p>This is for br tag</p><p>

</p><p>The stylesheet is doing some mischief</p><p>

</p><p>WHAT IS THE REASON ?</p><p>

</p><p>
</p><p>
</p><p>
</p><p>
</p><p>
</p><p>
</p><p>Is it not the proper syntax for matching<br/>
tag.</p><p>

</p><p>
</p><p>
</p>
</card></wml>

Here so many unwanted <p> and </p> .why? and how to remove them with
the condition that if some text is not in side of any tag but body it
shoud be outputted.
And if i want to test for <br /> that if it is just after a <a> or <li>
or <br /> then do not put <br /> in output.
I tried
<xsl:template match="br[not(preceding-sibling::node()[1][self::br])] |
br[not(preceding-sibling::node()[1][self::a])] |
br[not(preceding-sibling::node()[1][self::li])]">
	<br/>
</xsl:template>
but not working
