XSLT convert some elements into attribute and sorted by attribute value [duplicate] - xslt

I'm trying to transform this xml. However I'm having formatting issues. Could someone please guide me to solve this problem. Thanks in advance
<?xml version="1.0" encoding="windows-1252"?>
<XML>
<Attributes>
<Attribute>
<id>5</id>
<Name>Buyer ID</Name>
<Type>common</Type>
<Value>Lee</Value>
</Attribute>
<Attribute>
<id>331</id>
<Name>Enviornment</Name>
<Type>common</Type>
<Value>Development</Value>
</Attribute>
<Attribute>
<id>79</id>
<Name>Retail</Name>
<Type>common</Type>
<Value></Value>
</Attribute>
<Attribute>
<id>402</id>
<Name>Gender</Name>
<Type>category</Type>
<Value>Men</Value>

<id>41</id>
<Name>PlusShip</Name>
<Type>common</Type>
<Value>False</Value>
<Path></Path>
</Attribute>
</Attributes>
</XML>
Into the following XML. Could someone please give me some tips in how to transform this xml based on the value of Attributes/Attribute/Type
<?xml version="1.0" encoding="utf-8" ?>
<Data Schema="XML A">
<Attributes type="Common">
<Attr id="" name="Buyer ID" value="Lee" />
<Attr id="" name="Enviornment" value="Development" />
<Attr id="" name="Retail" value="" />
<Attr id="" name="PlusShip" value="False" />
</Attributes>
<Attributes type="Category">
<Attr id="" name="Gender" value="Men" />
<Attr id="" name="HeelHeight" value="" />
</Attributes>

Answer 1

The following stylesheet produces the desired result:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<Data Schema="XML A">
<xsl:apply-templates/>
</Data>
</xsl:template>
<xsl:template match="Attribute[not(Type=following::Type)]">
<Attributes type="{Type}">
<xsl:for-each select="../Attribute[Type=current()/Type]">
<Attr id="{id}" name="{Name}" value="{Value}"/>
</xsl:for-each>
</Attributes>
</xsl:template>
<xsl:template match="Attribute"/>
</xsl:stylesheet>
Output on your source document:
<Data Schema="XML A">
<Attributes type="category">
<Attr id="402" name="Gender" value="Men"/>
<Attr id="433" name="HeelHeight" value=""/>
</Attributes>
<Attributes type="common">
<Attr id="5" name="Buyer ID" value="Lee"/>
<Attr id="331" name="Enviornment" value="Development"/>
<Attr id="79" name="Retail" value=""/>
<Attr id="41" name="PlusShip" value="False"/>
</Attributes>
</Data>
Edit: OK, let's get rid of that ugly for-each:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<Data Schema="XML A">
<xsl:apply-templates/>
</Data>
</xsl:template>
<xsl:template match="Attribute[not(Type=following::Type)]">
<Attributes type="{Type}">
<xsl:apply-templates
select="../Attribute[Type=current()/Type]" mode="out"/>
</Attributes>
</xsl:template>
<xsl:template match="Attribute" mode="out">
<Attr id="{id}" name="{Name}" value="{Value}"/>
</xsl:template>
<xsl:template match="Attribute"/>
</xsl:stylesheet>
I feel much better.
Edit #2: Using the Muenchian Method (with sorting):
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="type" match="Attribute" use="Type"/>
<xsl:template match="/">
<Data Schema="XML A">
<xsl:apply-templates select="XML/Attributes/Attribute">
<xsl:sort select="Type" order="descending"/>
</xsl:apply-templates>
</Data>
</xsl:template>
<xsl:template
match="Attribute[generate-id()=generate-id(key('type', Type)[1])]">
<Attributes type="{Type}">
<xsl:apply-templates
select="../Attribute[Type=current()/Type]" mode="out"/>
</Attributes>
</xsl:template>
<xsl:template match="Attribute" mode="out">
<Attr id="{id}" name="{Name}" value="{Value}"/>
</xsl:template>
<xsl:template match="Attribute"/>
</xsl:stylesheet>
Produces the following (ordered) output:
<Data Schema="XML A">
<Attributes type="common">
<Attr id="5" name="Buyer ID" value="Lee"/>
<Attr id="331" name="Enviornment" value="Development"/>
<Attr id="79" name="Retail" value=""/>
<Attr id="41" name="PlusShip" value="False"/>
</Attributes>
<Attributes type="category">
<Attr id="402" name="Gender" value="Men"/>
<Attr id="433" name="HeelHeight" value=""/>
</Attributes>
</Data>
