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.

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0"     xmlns:xsl="http://www.w3.org/1999/xsl/transform">    <xsl:strip-space elements="*"/>   <xsl:output method="xml" indent="yes"/>    <xsl:template match="/country">     <xsl:copy>       <xsl:apply-templates select="*"/>     </xsl:copy>   </xsl:template>    <xsl:template match="info[@enum='ctry']">     <countryinfo>       <name>         <xsl:text>country name: </xsl:text>         <xsl:value-of select="@name"/>       </name>       <districts>         <xsl:value-of select="@total-states"/>       </districts>       <xsl:call-template name="state"/>     </countryinfo>   </xsl:template>    <xsl:template name="state">     <xsl:param name="i" select="1"/>     <xsl:if test="following-sibling::info[$i][@enum='st']">       <state>         <statename>           <xsl:text>state name: </xsl:text>           <xsl:value-of select="following-sibling::info[$i]/@name"/>         </statename>         <statepop>           <xsl:text>state population: </xsl:text>            <xsl:value-of select="following-sibling::info[$i]/@population"/>         </statepop>       </state>       <xsl:call-template name="state">         <xsl:with-param name="i" select="$i+1"/>       </xsl:call-template>     </xsl:if>   </xsl:template>  </xsl:stylesheet>

output

<?xml version="1.0" encoding="utf-8"?> <country>    <countryinfo>       <name>country name: united states 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>
