我的问题:我如何应用双重(或多重)分组？

这是源XML:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
    <row>
        <Type>1</Type>
        <WeaNr>100519</WeaNr>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100519</WeaNr>
        <ETADC_SKU>2007925</ETADC_SKU>
        <CrossDock>N</CrossDock>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100519</WeaNr>
        <ETADC_SKU>12007925</ETADC_SKU>
        <CrossDock>N</CrossDock>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100519</WeaNr>
        <ETADC_SKU>200792ww5</ETADC_SKU>
        <CrossDock>Y</CrossDock>
    </row>
    <row>
        <Type>1</Type>
        <WeaNr>100520</WeaNr>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100520</WeaNr>
        <ETADC_SKU>2007925444</ETADC_SKU>
        <CrossDock>N</CrossDock>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100520</WeaNr>
        <ETADC_SKU>2007925333</ETADC_SKU>
        <CrossDock>Y</CrossDock>
    </row>
    <row>
        <Type>2</Type>
        <WeaNr>100520</WeaNr>
        <ETADC_SKU>204445333</ETADC_SKU>
        <CrossDock>Y</CrossDock>
    </row>
</root>

我想用WeaNr和分组CrossDock

本案例中的预期结果为4组:

1. WeaNr=100519 and CrossDock=N
2. WeaNr=100519 and CrossDock=Y
3. WeaNr=100520 and CrossDock=N
4. WeaNr=100520 and CrossDock=Y

只需一个字段进行分组,就像WeaNr一样简单:

<xsl:for-each-group select="row" group-by="WeaNr">

那么我该如何应用双(或多个)分组？
