Hi,
I downloaded the source code of libxml2, compiled it and upgraded to version 2.13.4. It seems that the result is the
same.
I'm wondering whether the default libxml2 provided by different operating systems meets our requirements,
or if we need to specify a particular version of libxml2 externally?
```
xml.c: In function ‘xml_parse’:
xml.c:1919:25: error: ‘xmlKeepBlanksDefault’ is deprecated [-Werror=deprecated-declarations]
1919 | save_keep_blanks = xmlKeepBlanksDefault(preserve_whitespace ? 1 : 0);
