Fedora Update Notification
2018-01-30 17:59:49.778507

Name : libxml2
Product : Fedora 27
Version : 2.9.7
Release : 1.fc27
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.
In this case one can use the built-in XPath and XPointer implementation
to select sub nodes or ranges. A flexible Input/Output mechanism is
available, with existing HTTP and FTP modules and combined to an
URI library.
