Name : libxml2
Product : Fedora 33
Version : 2.9.10
Release : 8.fc33
Summary : Library providing XML and HTML support
Description :
This library allows to manipulate XML files. It includes support
to read, modify and write XML and HTML files. There is DTDs support
this includes parsing and validation even with complex DtDs, either
at parse time or later once the document has been modified. The output
can be a simple SAX stream or and in-memory DOM like representations.
