📄 Description

Relevant Issue (if applicable)

#2738 #2737

Details

The error :1: parser error: Document is empty may be output to stderr.
This occurs when calling the following function:

xmlDoc* xmlReadMemory(const char *buffer, int size, const char *URL, const char *encoding, int options)

This error is output when buffer is not nullptr and size is 0. (xmlDoc* returns nullptr.)
Therefore, we now check whether the data length is 0 before calling this function.

This fix is not a workaround for the current CI test failures in Ubuntu 25.10 and other releases.
