I couldn’t quite work out your logic but I think you may benefit from using a key here to look up the SecDef<\/code> element using its MktSegGrp<\/code> attribute value<\/p>\n

<xsl:key name=\"MktSeg\" match=\"SecDef\" use=\"MktSegGrp\/@MktSegID\" \/>\n<\/code><\/pre>\n
So, for a given MktDef<\/code>, you would get the SecDef<\/code> elements for it like so<\/p>\n
<xsl:variable name=\"secDef\" select=\"key('MktSeg', @MktSegID)\" \/>\n<\/code><\/pre>\n
Try this XSLT<\/p>\n
<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http:\/\/www.w3.org\/1999\/XSL\/Transform\" xmlns:fo=\"http:\/\/www.w3.org\/1999\/XSL\/Format\" >\n\n  <xsl:output method=\"text\"\/>\n\n  <xsl:key name=\"MktSeg\" match=\"SecDef\" use=\"MktSegGrp\/@MktSegID\" \/>\n\n  <xsl:template match=\"https:\/\/stackoverflow.com\/\">\n    <xsl:text>MktID,MktSegID,TxnTm,PriSetPx,QtSideInd,FastMktPctg,ImpldMktInd,MlegModel<\/xsl:text>\n    <xsl:text>&#xA;<\/xsl:text>\n    <xsl:for-each select=\"FIXML\/Batch\/MktDef\">\n      <xsl:variable name=\"secDef\" select=\"key('MktSeg', @MktSegID)\" \/>\n\n      <xsl:for-each select=\"BaseTrdgRules\">\n        <xsl:variable name=\"header\" select=\"concat(..\/@MktID,',', ..\/@MktSegID, ',', @QtSideInd, ',', @FastMktPctg)\" \/>\n        <xsl:choose>\n          <xsl:when test=\"$secDef\">\n            <xsl:for-each select=\"$secDef\">\n              <xsl:variable name=\"baseTrg\" select=\"MktSegGrp\/SecTrdgRules\/BaseTrdgRules\" \/>\n              <xsl:value-of select=\"concat($header, ',', @TxnTm, ',', @PriSetPx, ',', $baseTrg\/@ImpldMktInd, ',', $baseTrg\/@MlegModel, '&#xA;')\"\/>\n            <\/xsl:for-each>\n          <\/xsl:when>\n          <xsl:otherwise>\n            <xsl:value-of select=\"concat($header, ',,,,&#xA;')\"\/>\n          <\/xsl:otherwise>\n        <\/xsl:choose>\n      <\/xsl:for-each>\n    <\/xsl:for-each>\n  <\/xsl:template>\n<\/xsl:stylesheet>\n<\/code><\/pre>\n<\/p><\/div>\n
