How to select an attribute based on another attribute's value

Question

I need to select the NativeDescription value when Credit_Term_Code=\"4\" by looping in XSLT:

Answer 1

To select the NativeDescription attribute of the Credit_Term_parent element with a Credit_Term_Code equal to 4, use one of the following XPaths:

1. If the ancestral structure above Credit_Term_parent is fixed as shown:

   /Credit_code_parents/Credit_Term_parent[@Credit_Term_Code='4']/@NativeDescription
   

2. If there's potentially variable ancestral structure above Credit_Term_parent (and assuming that the provided Credit_Term_Code is unique across the document):

   //Credit_Term_parent[@Credit_Term_Code='4']/@NativeDescription
   

You ask for XSLT looping code:

Or, without the loop:

...or, alternatively, use the XPath from #1 above instead of the one from #2.
