XSLT Req

Question

Hi Folks,
Can anyone there help me out as to whether the following req can be done using XSLT, and if so how?
Here is what I need.
<Ship>
<SInfo>
  <SegmentIdentifier>ABC</SegmentIdentifier>
  <ShipTo>0004100357</ShipTo>
  <PCount>2</PCount>
  <SWeight>30</SWeight>
  <UOM>KG</UOM>
</SInfo>
<SInfo>
  <SegmentIdentifier>ABC</SegmentIdentifier>
  <ShipTo>0004100357</ShipTo>
  <PCount>3</PCount>
  <SWeight>25</SWeight>
  <UOM>KG</UOM>
</SInfo>
<SInfo>
  <SegmentIdentifier>ABC</SegmentIdentifier>
  <ShipTo>0004100357</ShipTo>
  <PCount>2</PCount>
  <SWeight>20</Sweight>
  <UOM>KG</UOM>
</SInfo>
<SInfo>
  <SegmentIdentifier>ABC</SegmentIdentifier>
  <ShipTo>0004100300</ShipTo>
  <PCount>2</PCount>
  <SWeight>30</SWeight>
  <UOM>KG</UOM>
</SInfo>
</Ship>
The requirement of the xslt is to convert the xml to a flat-file structure. The output for the above example should be flat file with value as below,
ABC00041003577  75 KG
ABC00041003002  30 KG
The lengths of the fields are mentioned below,
Length of SegmentIdentifier field - 3
Length of ShipTo field - 10
Length of PCount field - 3
Length of SWeight field - 4
Length of UOM field - 2
So based on these lengths in the flatfile o/p shown above, the first 3 characters represent 'SegmentIdentifier', next 10 represent 'ShipTo' etc. If the field is of lesser length, then they should be replaced by spaces.
Take the first line of the flatfile output,
ABC00041003577  75 KG
This is basically arrived using the following condition, we should check for the all the SInfo segment having same 'ShipTo' field and then once that is identified, we should basically sum the corresponding PCount (232=7) and SWeight (302520=70) and append it to the flatfile.
But if the ShipTo is unique then each segment should have a separate line (as seen in the second line of the flat-file)
I hope i have written my requirement clearly, if i get some help on this, i can build upon this xslt and go ahead coding the rest.
thanks

Hi Sammy,
I found a solution with 2 styles, one sorting, one recursiv. It was not easy...
First
[code]
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="/">
          <Ship>
               <xsl:for-each select="//SInfo">
                    <xsl:sort select="ShipTo" order="ascending" data-type="number"/>
                    <xsl:copy-of select="."/>
               </xsl:for-each>
          </Ship>
     </xsl:template>
</xsl:stylesheet>
[/code]
Second
[code]
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output method="text" omit-xml-declaration="yes" media-type="text/plain"/>
     <xsl:template match="/">
          <xsl:call-template name="row">
               <xsl:with-param name="ShipTo" select="0"/>
          </xsl:call-template>
     </xsl:template>
     <xsl:template name="row">
          <xsl:param name="ShipTo"/>
          <xsl:variable name="ConstShipTo">
               <xsl:value-of select="$ShipTo"/>
          </xsl:variable>
          <xsl:if test="$ShipTo != 0 ">
               <xsl:value-of select="//SegmentIdentifier[../ShipTo=$ShipTo]"/>
               <xsl:value-of select="$ShipTo"/>
               <xsl:value-of select="sum(//PCount[../ShipTo=$ConstShipTo])"/>
               <xsl:text> </xsl:text>
               <xsl:value-of select="sum(//SWeight[../ShipTo=$ConstShipTo])"/>
               <xsl:text> </xsl:text>
               <xsl:value-of select="//UOM[../ShipTo=$ShipTo]"/>
               <xsl:text>
</xsl:text>
          </xsl:if>
          <xsl:if test="//ShipTo > $ShipTo">
               <xsl:call-template name="row">
                    <xsl:with-param name="ShipTo" select="//ShipTo [. > $ShipTo]"/>
               </xsl:call-template>
          </xsl:if>
     </xsl:template>
</xsl:stylesheet>
