Mule changing the file name/extension for storing multiple files after splitter

Question

I am trying to split a xml and store it as different files. The files get stored correctly in .dat format if I dont specify anything in the File name/pattern option . But i want the files to be stored as something.xml format like a1.xml ,a2.xml ,a3.xml .

Here is the flow I am trying

            <?xml version="1.0" encoding="UTF-8"?>

            </mule>

Answer 1

Your outputPattern attribute is just ".xml". if you look in src/test/resources is suspect you will find a file called .xml containing the last split contents.

You need to proved an expression for the outputPattern attribute, something like:

<mulexml:dom-to-xml-transformer doc:name="DOM to XML"/>
   <file:outbound-endpoint path="src/test/resources" outputPattern="#[xpath3(&quot;//name&quot;,payload)].xml" responseTimeout="10000" doc:name="File"/>
</flow>
