I am trying to use the XPATH expression "//" to find all matches of an element name no matter where they exist in the XML document. For example ..
count(//process_data/xml_data//User)
it correctly returns a value of 5 on my test XML document. Great. How would I go about grabbing the 3rd match or perhaps iterating through all matches?
I have tried the following
//process_data/xml_data//User[1]
this works. However, the following doesn't work
//process_data/xml_data//User[2]
It says the XML variable I assign the expression to is <empty>
I even tried to get it to work with a list variable (xml subtype) and assign //process_data/xml_data//User to the variable. That doesn't work, it shows <list><null/></list> as the result.
I created an xml variable and assign //process_data/xml_data//User to the variable. That doesn't work, it only shows the 1st match.
Any ideas?
One of the LC Knowledge bases specificaly says this.
/process_data/formVariable/object/data/xdp/datasets/data//TextField1 returns "Hello world 1...", "Hello world 2...", and "Hello world 3..." and therefore is more flexible if the exact structure of an XML is not known (for example, when using a relative path).
