Help on large grouping in DataTemplate

Question

Hi Guro
I need som help on BI Publisher 10.1.3.2.1.
The following sql works. The join works. The select works seperatly in DataTemplates, but when put together it seems to large!
The Opera browser have the most informative error:
XML parsing failed: syntax error (Line: 1, Character: 0)
Error:missing root element
The DataTemplete works (without the proper grouping) until I add <group name="G_WPO2" source="WPO">
What to do?
How do I find the real causing error?
Any suggestions on runtimeparameters like cache and size?
Expected filesize on xlmoutput is only 100kb
Any hint will be appreciated. Thanks.
I'm using a DataTemplate as follows.
<dataTemplate name="CP1-template" dataSourceRef="MinEupa_pdf" description="test" version="1.0">
<parameters>
<parameter name="p_ip" dataType="character" defaultValue="123.7"/>
<parameter name="p_up" dataType="character" defaultValue="-99"/>
<parameter name="p_dp" dataType="character" defaultValue="2"/>
<parameter name="p_ec" dataType="character" defaultValue=""/>
</parameters>
<dataQuery>
<sqlStatement name="OB">
     select * from mineupa.xml_ob
     where OB_DP_ID = to_number(:p_dp)

Hi Iceman
Thanks for your tip. Im trying with CDATA then:
<dataTemplate name="CP1-template" dataSourceRef="MinEupa_pdf" description="test">
     <parameters>
          <parameter name="p_ip" dataType="character" defaultValue="123.7"/>
          <parameter name="p_up" dataType="character" defaultValue="-99"/>
          <parameter name="p_dp" dataType="character" defaultValue="2"/>
          <parameter name="p_ec" dataType="character" defaultValue=""/>
     </parameters>
     <dataQuery>
          <sqlStatement name="OB"><![CDATA[
     select * from mineupa.xml_ob
     where OB_DP_ID = to_number(:p_dp)
]]></sqlStatement>
          <sqlStatement name="WP"><![CDATA[
     select * from xml_wp
     where WP_DP_ID = :p_dp
     and WP_OB_ID = :OB_ID
]]></sqlStatement>
          <sqlStatement name="WPO"><![CDATA[
     select * from mineupa.xml_wpo
     where WPO_DP_ID = :p_dp
]]></sqlStatement>
          <sqlStatement name="DL"><![CDATA[
     select * from mineupa.xml_deliverable
     where DL_DP_ID = :p_dp
]]></sqlStatement>
     </dataQuery>
     <dataStructure>
          <group name="G_OB" source="OB">
               <element name="OB_ID" value="OB_ID"/>
               <group name="G_WP" source="WP">
                    <element name="WP_ID" value="WP_ID"/>
                    <element name="WP_OB_ID" value="WP_OB_ID"/>
                         <element name="WPO_ID" value="WPO_ID"/>
                         <element name="WPO_WP_ID" value="WPO_WP_ID"/>
                              <element name="DL_ID" value="DL_ID"/>
               </group>
          </group>
     </dataStructure>
</dataTemplate>
Works by returning:
<?xml version="1.0" encoding="UTF-8" ?>
- <CP1-TEMPLATE>
<p_dp>2</p_dp>
- <LIST_G_OB>
- <G_OB>
<OB_ID>1001</OB_ID>
</G_OB>
- <G_OB>
<OB_ID>2</OB_ID>
- <LIST_G_WP>
- <G_WP>
<WP_ID>1003</WP_ID>
<WP_OB_ID>2</WP_OB_ID>
<WPO_ID />
<WPO_WP_ID />
<DL_ID />
</G_WP>
- <G_WP>
<WP_ID>1000</WP_ID>
<WP_OB_ID>2</WP_OB_ID>
<WPO_ID />
<WPO_WP_ID />
<DL_ID />
</G_WP>
</LIST_G_WP>
</G_OB>
- <G_OB>
<OB_ID>3</OB_ID>
But still when trying to merge like this it fails:
<dataTemplate name="CP1-template" dataSourceRef="MinEupa_pdf" description="test">
     <parameters>
          <parameter name="p_ip" dataType="character" defaultValue="123.7"/>
          <parameter name="p_up" dataType="character" defaultValue="-99"/>
          <parameter name="p_dp" dataType="character" defaultValue="2"/>
          <parameter name="p_ec" dataType="character" defaultValue=""/>
     </parameters>
     <dataQuery>
          <sqlStatement name="OB"><![CDATA[
     select * from mineupa.xml_ob
     where OB_DP_ID = to_number(:p_dp)
]]></sqlStatement>
          <sqlStatement name="WP"><![CDATA[
     select * from xml_wp
     where WP_DP_ID = :p_dp
     and WP_OB_ID = :OB_ID
]]></sqlStatement>
          <sqlStatement name="WPO"><![CDATA[
     select * from mineupa.xml_wpo
     where WPO_DP_ID = :p_dp
     and WPO_WP_ID=:WP_ID
]]></sqlStatement>
          <sqlStatement name="DL"><![CDATA[
     select * from mineupa.xml_deliverable
     where DL_DP_ID = :p_dp
     and DL_WPO_ID=:WPO_ID
]]></sqlStatement>
     </dataQuery>
     <dataStructure>
          <group name="G_OB" source="OB">
               <element name="OB_ID" value="OB_ID"/>
               <group name="G_WP" source="WP">
                    <element name="WP_ID" value="WP_ID"/>
                    <element name="WP_OB_ID" value="WP_OB_ID"/>
                    <group name="G_WPO" source="WPO">
                         <element name="WPO_ID" value="WPO_ID"/>
                         <element name="WPO_WP_ID" value="WPO_WP_ID"/>
                         <group name="G_DL" source="DL">
                              <element name="DL_ID" value="DL_ID"/>
                         </group>
                    </group>
               </group>
          </group>
     </dataStructure>
</dataTemplate>
