A current problem I am trying to solve is generating a comparison of two xml files with differences and similarities via xslt. For example the first xml file looks like \[code\]<?xml version="1.0" encoding="utf-8" ?><Stats Date="2011-01-01"> <Player Rank="1"> <GP>39</GP> <G>32</G> <A>33</A> <PlusMinus>20</PlusMinus> <PIM>29</PIM> <PP>10</PP> <SH>1</SH> <GW>3</GW> <Shots>0</Shots> <ShotPctg>154</ShotPctg> <TOIPerGame>20.8</TOIPerGame> <ShiftsPerGame>21:54</ShiftsPerGame> <FOWinPctg>22.6</FOWinPctg> </Player></Stats>\[/code\]The second file looks like \[code\]<?xml version="1.0" encoding="utf-8" ?><Stats Date="2011-01-01"> <Player Rank="2"> <Name>John Smith</Name> <Team>NY</Team> <Pos>D</Pos> <GP>38</GP> <G>32</G> <A>33</A> <PlusMinus>15</PlusMinus> <PIM>29</PIM> <PP>10</PP> <SH>1</SH> <GW>4</GW> <Shots>0</Shots> <ShotPctg>158</ShotPctg> <TOIPerGame>20.8</TOIPerGame> <ShiftsPerGame>21:54</ShiftsPerGame> <FOWinPctg>22.6</FOWinPctg> </Player></Stats>\[/code\]When I embed the second file into the xslt file the output works as expected:\[code\]<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl
