I had a problem in xsl:for-each-group and it was very nicely solved in here. Now I have some other problem. I have like this as input.
<?xml version="1.0" encoding="UTF-8"?>
<body>
<p name ="section">this is section</p>
<p name="h-title" other="main">Introduction</p>
<p name="h1-title " other="other-h1">XSLT and XQuery</p>
<p name="h2-title" other=" other-h2">XSLT</p>
<p name="">
<p1 name="bold"> XSLT is used to write stylesheets.</p1>
</p>
<p name="h2-title " name="other-h2">XQuery</p>
<p name="">
<p1 name="bold"> XQuery is used to query XML databases.</p1>
</p>
<p name="h3-title" name="other-h3">XQuery and stylesheets</p>
<p name="">
<p1 name="bold"> XQuery is used to query XML databases.</p1>
</p>
<p name ="section">this is section</p>
<p name="h1-title " other="other-h1">XSLT and XQuery</p>
<p name="h2-title " other=" other-h2">XSLT</p>
<p name ="section">this is section</section>
<p name="h1-title " other="other-h1">XSLT and XQuery</p>
<p name="h2-title " other=" other-h2">XSLT</p>
</body>
Now my wanted output is this
<?xml version="1.0" encoding="UTF-8"?>
<body>
<p name="h-title " other="main">Introduction</p>
<section>
<p name ="section">this is section</p>
<h1>
<p name="h1-title " other="other-h1"> XSLT and XQuery </p>
<h2>
<p name="h2-title " other="other-h2">XSLT</p>
<p name="">
<p1 name="bold">XSLT is used to write stylesheets.
</p1>
</p>
</h2>
<h2>
<p name="h2-title " other="other-h2"> XQuery is used to query XMLdatabases
</p>
<p name="">
<p name="bold"> XQuery is used to query XML databases.</p>
</p>

<p name="h3-title " name="other-h3">XQuery and stylesheets</p>
<p name="">
<p1 name="bold"> XQuery is used to query XML databases.</p1>
</p>

<p name ="section">this is section</p>

My used stylesheet(not working properly)
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:mf="http://example.com/mf"
exclude-result-prefixes="xs mf">
<xsl:param name="prefix" as="xs:string" select="'h'"/>
<xsl:param name="suffix" as="xs:string" select="'-title'"/>
<xsl:output method="html" version="4.0" indent="yes"/>
<xsl:function name="mf:group" as="node()*">
<xsl:param name="items" as="node()*"/>
<xsl:param name="level" as="xs:integer"/>
<xsl:for-each-group select="$items" group-starting-with="p[@name = concat($prefix,$level, $suffix)]">
<xsl:choose>
<xsl:when test="not(self::p[@name = concat($prefix, $level, $suffix)])">
<xsl:apply-templates select="current-group()"/>
</xsl:when>
<xsl:otherwise>
<xsl:element name="h{$level}">
<xsl:apply-templates select="."/>
<xsl:sequence select="mf:group(current-group() except ., $level + 1)"/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:function>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* , node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="body" name ="myTemplate">
<xsl:copy>
<xsl:sequence select="mf:group(*, 1)"/>
</xsl:copy>
</xsl:template>
<xsl:template match="body[@name='section']">
<section>
<xsl:call-template name="myTemplate"/>
</section>
</xsl:template>
</xsl:stylesheet>
But this is not correct. Things like <p name ="section">this is section</p> appear widely. not only that, there are few others like this. If someone please show me how to handle with section I will be able to do that for others too. Please tell me how to do this correctly.

I think you mainly want another grouping step; the stylesheet
transforms the corrected input
into the result
That has the structure you posted I think, with the exception of the
<p name="h-title" other="main">Introduction</p>element being inside a section while your posted example moved it to the top. I am not sure what are the rules for doing that so I have not tried to implement that. Please clarify whether you simply want to move that single element to the top and not apply the grouping to it or whether there are more complex rules to exempt certain elements.[edit]In case you simply want to move all
p[@name = 't-title']to the top and not group them then the following adaption of above stylesheet should do the job:
