Help in suppressing Adobe Fields

Question

Hello all,
I am new to Adobe forms livecycle designer, apologies if it is a basic question. My requirement is as below:
1. Based on the data in my xml data file may be one field some where in the file, I should be able to suppress other fields in the form. What is the event I should be writing my script on, I have seen this discussion http://forums.adobe.com/thread/861342, but it is on the click of a radiobutton, want something which happens on seeing the data.
Also how will I check the data field, because the form element can be suppresed by xfa[0].form[0].Invoice[0].Subform3[1].MonetaryAmount[4].presence = "inactive";
2. A segment in my invoice XML keeps repeating, but the identifier and the amount keep changing for every occurence of taxsummary. Example as below the target fields in my adobe form have to populated based on the <Ident> field, if it GST put <TaxableAmount> to TAX_GST, if it PST put <TaxableAmount> to TAX_PST.
<TaxSummary>
     <Tax>
         <TaxTypeCodedOther>
             <Identifier>
                 <Agency>
                     <AgencyCoded>Other</AgencyCoded>
                         <AgencyCodedOther>GST</AgencyCodedOther>
                         </Agency>
                             <Ident>GST</Ident>
                         </Identifier>
                     <TaxableAmount>52500.00</TaxableAmount>
         </TaxTypeCodedOther>
     </Tax>
</TaxSummary>
<TaxSummary>
     <Tax>
         <TaxTypeCodedOther>
             <Identifier>
                 <Agency>
                     <AgencyCoded>Other</AgencyCoded>
                         <AgencyCodedOther>GST</AgencyCodedOther>
                         </Agency>
                             <Ident>PST</Ident>
                         </Identifier>
                     <TaxableAmount>9500.00</TaxableAmount>
         </TaxTypeCodedOther>
     </Tax>
</TaxSummary>
<TaxSummary>
     <Tax>
         <TaxTypeCodedOther>
             <Identifier>
                 <Agency>
                     <AgencyCoded>Other</AgencyCoded>
                         <AgencyCodedOther>GST</AgencyCodedOther>
                         </Agency>
                             <Ident>HST</Ident>
                         </Identifier>
                     <TaxableAmount>1500.00</TaxableAmount>
         </TaxTypeCodedOther>
     </Tax>
</TaxSummary>
Can anyone please provide any solution for my problem
