nonempty check for an element at the same level

[msambasiva@gmail.com]

Hi,

XSLT2.0

I am trying to find the element names and count which are nonempty at any level

Ex:

<custom-data>
  <schema>XXXschema>
  <object-name>YYYYY</object-name>
  <short-name>YYYYY</short-name>
  <object-type>TABLE</object-type>
  <mls-support-model/>
  <object-owner>PPPP</object-owner>
  <status/>
  <columns>
    <columns>
      <name>ID</name>
      <datatype>NUMBER</datatype>
      <length/>
      <precision/>
      <not-null>Yes</not-null>
      <comments>Identifier of the aging bucket.</comments>
      <flexfield-mapping/>
      <status/>
    </columns>
    <columns>
      <name>LAST_UPDATED_BY</name>
      <datatype>VARCHAR2</datatype>
      <length>64</length>
      <precision/>
      <not-null>Yes</not-null>
      <comments>Who column: indicates the user who last updated the row.</comments>
      <flexfield-mapping/>
      <status/>
    </columns>
    <columns>
      <name>ATTRIBUTE8</name>
      <datatype>VARCHAR2</datatype>
      <length>150</length>
      <precision/>
      <not-null/>
      <comments>Descriptive Flexfield: segment of the user descriptive flexfield.</comments>
      <flexfield-mapping>Aging </flexfield-mapping>
      <status/>
    </columns>
  </columns>
</custom-data>

I want to generate a table from the above data. The trick is, if there is no data for a column at any where, we need to exclude that column from the output table.

Ex: status,precision elements is empty for all the columns. SO we don't need to display status and precision column in output table.

How to get the number of elements without data at the same level and there names?

Thanks,

Samba.
