But with interactive interface I have the error:
<ino:message ino:returnvalue=“8738”>
<ino:messagetext ino:code=“INOXPE8738”>Only a single document may be processed.</ino:messagetext> ino:messagelineLine 6, Column 38: Only a single document may be changed.</ino:messageline>
</ino:message>
now the format is correct. If you put multiple XML documents into one file, you have o warp each one ino the ino:object tag. The reason is that XMl allows comments and processing instructions before and after the root element, and thus wrapping is the only means to know which of these belong to which document.
the Tamino data loader also supports loading of multiple XML documents at a time if these are in a separate file per XML document
