[xml] [xpath] How to print xml fragment

[bagnacauda <bagnacauda gmail com>]

Hello,

 

I hope someone can help me with this problem.

 

My input xml file has got a recurring structure "TransactionError" as follows:

 

......
  <TransactionErrorRecords>
   <TransactionError>
    <TransactionErrorReference>bbb</TransactionErrorReference>
    <TransactionErrorMessage>ccc</TransactionErrorMessage>
   </TransactionError>
   <TransactionError>
    <TransactionErrorReference>ddd</TransactionErrorReference>
    <TransactionErrorMessage>eee</TransactionErrorMessage>
   </TransactionError>

.......
  </TransactionErrorRecords>

 

I need to extract the content of the xml file (as a string) between each couple <TransactionError>,</TransactionError>, the two tags included.

So I basically need to be able to populate a string in a loop with

   <TransactionError>
    <TransactionErrorReference>bbb</TransactionErrorReference>
    <TransactionErrorMessage>ccc</TransactionErrorMessage>
   </TransactionError>
 

then with

 

   <TransactionError>
    <TransactionErrorReference>ddd</TransactionErrorReference>
    <TransactionErrorMessage>eee</TransactionErrorMessage>
   </TransactionError>

 

and so on

 

I can identify the nodeset (all TransactionError's) with an xpath _expression_ but then how can I get the string value? I've tried to use the xpath2.c example as a guide by printing cur->content when cur=TransactionError but it won't work.

 

Thanks in advance,

Massimo

    <TransactionErrorMessage>eee</TransactionErrorMessage>
   </TransactionError>
