xslt - Categorize XML based on element attribute type -

with xml input unable add elements specific sections.

<country>   <info enum="ctry" name="united sates of america" total-states="50" />   <info enum="st" name="new york" population="8,244,910"/>   <info enum="st" name="chicago" population="2,707,120"/>   <info enum="ctry" name="germany" total-states="16"/>   <info enum="st" name="berlin" population="3,469,910"/>   <info enum="st" name="brandenburg" population="2,500,000"/> </country> 

here xsl,

<xsl:template match="/">   <country>     <xsl:for-each select="country/info">       <xsl:if test="@enum='ctry'">         <countryinfo>           <name>country name: <xsl:value-of select="@name"/></name>           <districts><xsl:value-of select="@total-states"></xsl:value-of></districts>           <xsl:for-each select="/country/info">             <xsl:if test="@enum='st'">               <state>                 <statename>state name: <xsl:value-of select="@name"/></statename>                 <statepop>state population: <xsl:value-of select="@population"/></statepop>               </state>             </xsl:if>           </xsl:for-each>         </countryinfo>       </xsl:if>     </xsl:for-each>   </country> </xsl:template> 

the problem states showing both countries.

here xml output trying generate,

<country>   <countryinfo>     <name>country name: united sates of america</name>     <districts>50</districts>     <state>       <statename>state name: new york</statename>       <statepop>state population: 8,244,910</statepop>     </state>     <state>       <statename>state name: chicago</statename>       <statepop>state population: 2,707,120</statepop>     </state>   </countryinfo>   <countryinfo>     <name>country name: germany</name>     <districts>16</districts>     <state>       <statename>state name: berlin</statename>       <statepop>state population: 3,469,910</statepop>     </state>     <state>       <statename>state name: brandenburg</statename>       <statepop>state population: 2,500,000</statepop>     </state>   </countryinfo> </country> 

is possible accomplish xslt?

your source dreadful abuse of xml! should complain bitterly whoever designed , provided such rubbish.

with single template can't more remove or expand on elements in source.

i believe transform need. works copying country root element , processing contents. second template matches of info elements have enum attribute of ctry, form basis countryinfo output elements.

the state information has done recursively, using call-template insert information following info element if has enum attribute of st.

because of structure of source data transform fragile, , break if there unexpected elements. please beware.

output
