Dear XSL List, I think your main problem is that you are using // <xsl:for-each select="//Record"> <xsl:if test="Series=$SER"> here you are recursively searching the entire document looking for Record elements, and then only using them if Series=$SER so i suspect all your Record elements are siblings 9so you don't want //) and you can filter on Series, so <xsl:for-each select="Record[Series=$SER]" except that if you had already done a for-each-group, grouping on Series then there is no need to search the whole document, filtering of series, you just want the records in this group, ie select="current-group()" similiarly here: > <xsl:variable name="BOX" select="Box"/> > <xsl:for-each-group select="//Record" group-by="FolderID"> > <xsl:if test="Box=$BOX"> You are seraching the entire document at all levels but you just want the Records that have already been grouped by Box so thi sis again select="current-group() I'm not sure I fully understood the output format you gave, and teh input wansn't a full document so I wrapped it in <r>, but possibly something like the following <r> <Record> <Series>2</Series> <Subseries>1</Subseries> <Box>12</Box> <Folder>17</Folder> <FolderTitle>Symphonic Poem</FolderTitle> <FolderID>223</FolderID> </Record> <Record> <Series>2</Series> <Subseries>1</Subseries> <Box>12</Box> <Folder>18</Folder> <FolderTitle>Requeim Mass</FolderTitle> <FolderID>224</FolderID> </Record> <Record> <Series>2</Series> <Subseries>2</Subseries> <Box>12</Box> <Folder>19</Folder> <FolderTitle>Symphony no. 4</FolderTitle> <FolderID>225</FolderID> </Record> <Record> <Series>3</Series> <Box>12</Box> <Folder>20</Folder> <FolderTitle>Symphony no. 5</FolderTitle> <FolderID>226</FolderID> </Record> <Record> <Series>3</Series> <Box>13</Box> <Folder>1</Folder> <FolderTitle>Chamber music</FolderTitle> <FolderID>227</FolderID> <Item>String Quartet</Item> </Record> <Record> <Series>3</Series> <Box>13</Box> <Folder>1</Folder> <FolderTitle>Chamber music</FolderTitle> <FolderID>227</FolderID> <Item>String Quartet no. 2</Item> </Record> <Record> <Series>3</Series> <Box>13</Box> <Folder>1</Folder> <FolderTitle>Chamber music</FolderTitle> <FolderID>227</FolderID> <Item>Piano Trio Quartet</Item> </Record> </r> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes" omit-xml-declaration="yes"/> <xsl:template match="r">
