Sequences in XSLT

my xml input -

<?xml version="1.0" encoding="UTF-8"?> 
<foo>  <bar>bar</bar> 
       <bar>bar</bar> 
       <foobar>foobar</foobar> 
       <foobar>foobar</foobar> 
       <foobar>foobar</foobar>
       <bar>bar</bar>
       <bar>bar</bar> 
</foo>

The output using xslt should be

 <?xml version="1.0" encoding="UTF-8"?>

 <foo>  
 <s> 
 <s> 
 <bar>bar</bar>  
 <bar>bar</bar>
 </s>
 <s> 
 <foobar>foobar></foobar>
 <foobar>foobar></foobar>
 <foobar>foobar></foobar>
 </s> 
 <s>      
 <bar>bar</bar>  
 <bar>bar</bar> 
 </s>
 </s>
</foo>

The output must have a sequence of elements inside the parent. A mixed sequence of elements will move inside the parents of node "s". Is there any xslt command that defines the sequence and processes the xml accordingly. Many thanks.

Same as here , use the identifier of the first previous brother, whose name is different for grouping records:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:key name="adjacentByName" match="foo/*" use="generate-id(preceding-sibling::*[not(name()=name(current()))][1])" />

<xsl:template match="/">
<foo><s>
    <xsl:for-each select="foo/*[generate-id()=generate-id(key('adjacentByName', generate-id(preceding-sibling::*[not(name()=name(current()))][1]))[1])]">
        <s>
            <xsl:for-each select="key('adjacentByName', generate-id(preceding-sibling::*[not(name()=name(current()))][1]))">
                <xsl:copy-of select="."/>
            </xsl:for-each>
        </s>
    </xsl:for-each>
</s></foo>
</xsl:template>

</xsl:stylesheet>

Added:

But the conclusion that I get is not the same as my desired result ...

When applied to your (cleaned) input:

<?xml version="1.0" encoding="UTF-8"?> 
<foo>
    <bar>bar</bar> 
    <bar>bar</bar> 
    <foobar>foobar</foobar> 
    <foobar>foobar</foobar> 
    <foobar>foobar</foobar>
    <bar>bar</bar>
    <bar>bar</bar> 
</foo>

result:

<?xml version="1.0" encoding="utf-8"?>
<foo>
  <s>
    <s>
      <bar>bar</bar>
      <bar>bar</bar>
    </s>
    <s>
      <foobar>foobar</foobar>
      <foobar>foobar</foobar>
      <foobar>foobar</foobar>
    </s>
    <s>
      <bar>bar</bar>
      <bar>bar</bar>
    </s>
  </s>
</foo>

, :

<?xml version="1.0" encoding="UTF-8"?>

 <foo>  
 <s> 
 <s> 
 <bar>bar</bar>  
 <bar>bar</bar>
 </s>
 <s> 
 <foobar>foobar></foobar>
 <foobar>foobar></foobar>
 <foobar>foobar></foobar>
 </s> 
 <s>      
 <bar>bar</bar>  
 <bar>bar</bar> 
 </s>
 </s>
</foo>

> <foobar>, .
