Xslt 分组XML元素
我正在尝试对以下XML进行分组：Xslt 分组XML元素,xslt,xslt-2.0,Xslt,Xslt 2.0,我正在尝试对以下XML进行分组： <?xml version="1.0" encoding="UTF-8"?> <EDIFACT segmentDelimiter="'" itemDelimiter="+" elementDelimiter=":" decimalCharacter="." escapeCharacter="?"> <Envelope count='1'> <UNB>
<?xml version="1.0" encoding="UTF-8"?>

这几乎是正确的。我只遗漏了结果中的第一个
CPS组时，为了避免包装不属于组的元素，我建议使用
