Since you know the element names in the header, I guess you can list
the elements in the header. In which case, you can select the rows
that you're interested in with:

  row[not(column[position() = $header/AAA or
                 position() = $header/BBB or
                 position() = $header/CCC or
                 position() = $header/DDD]
                [not(normalize-space())])]

where $header is set with:

<xsl:variable name="header" select="/root/header" />
                
In other words: select the rows that do not have a column whose
position is one of the positions specified in the header but that does
not have any non-whitespace content.

Cheers,

Jeni
