sorting - XSLT sort by tag name and attribute value -

i'm noob xslt, please excuse ignorance... i'm trying sort simple xml file attribute value , tag name, struggle in accessing value of attribute. here complete example:

<a>     <b attribute="e"></b>     <b attribute="b"></b>     <d attribute="a"></d>     <c></c> </a> 

and expected result is:

<a>     <b attribute="b"></b>     <b attribute="e"></b>     <c></c>     <d attribute="a"></d> </a> 

here attempt solve this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">     <xsl:output indent="yes" />     <xsl:strip-space elements="*" />      <xsl:template match="node()|@*">         <xsl:copy>             <xsl:apply-templates select="@*">                 <xsl:sort select="."/>             </xsl:apply-templates>              <xsl:apply-templates select="node()">                 <xsl:sort select="name()"/>             </xsl:apply-templates>         </xsl:copy>     </xsl:template> </xsl:stylesheet> 

and don't work @ all...

in above example want sort b tag attribute value can see d tag not sorted attribute value because it's tag name...

i wonder if possible using xslt... have idea?

thanks in advance.

update----------------------

i tried andyb solution seems work fine , looks pretty simple, have issue solution.

let's have xml:

<a>     <b attribute="e" optionalattr="fg"></b>     <b attribute="b"></b>     <d attribute="a"></d>     <c></c> </a> 

i added optional parameter b tag. applying andyb solution optional parameter ignored, because not matched in template. here result:

<a>     <b attribute="b"></b>     <b attribute="e"></b>     <c></c>     <d attribute="a"></d> </a> 

instead of following expect:

<a>     <b attribute="b"></b>     <b attribute="e" optionalattr="fg"></b>     <c></c>     <d attribute="a"></d> </a> 

do have idea? in advance.

you can use multiple xsl:sort instructions, example:

<xsl:template match="node()|@*">   <xsl:copy>     <xsl:apply-templates select="node()|@*">       <xsl:sort select="name()" />       <xsl:sort select="@*" />     </xsl:apply-templates>   </xsl:copy> </xsl:template> 

and since default data-type "text" , default order "ascending" gives desired output.

edit

this strange, because following xml:

<a>     <b attribute="e" optionalattr="fg"></b>     <b attribute="b"></b>     <d attribute="a"></d>     <c></c> </a> 

and xsl above, result:

<a>     <b attribute="b"></b>     <b attribute="e" optionalattr="fg"></b>     <c></c>     <d attribute="a"></d> </a> 

this includes desired optional attribute order different xml in edited question (<c></c> in different position).
