I was asked to generate a comma separated list generated from an XML document. When the discounts only consisted of nodes grouped together under the vehicle node it worked OK (I have limited understanding of XPath). Then I was asked to add one more discount that is located in a different section of the XML. Using this approach I can't seem to get the value of the node I need. For clarification, I don't create this XML file, it is generated by a vendor system and is roughly 5K lines long. I used this post from SO as the basis for creating the list.
Desired Output (if node in loop != '0' or PaymentPlanCd != 'PaidInFull' add to the list - psuedo-code)
Multi-Car, Homeowner, Affinity, In-Agency Transfer, Advanced Purchase, Incident Free, Annual Mileage, Paid in Full Discount
I was getting an extra comma at the end so I changed to a whitespace based approach that seemed to work (Method 2). I would rather have the comma based approach (Method 1) though. Below is a sample of the XML document and the code I'm currently trying to make work. If there is an easier or more eloquent solution, I'm all ears.
Sample XML (@pval stands for "Proposal Value")

<PaymentPlanCd>PaidInFull</PaymentPlanCd>

<DiscountPremInAgencyTransfer pval="In-Agency Transfer">57</DiscountPremInAgencyTransfer>

How would I get method 1 working in this scenario? Thanks for all the help.
