I'm using XML::LibXML to read a large xml file. Below is a snippet of the code:
use XML::LibXML::Pattern;
next unless $reader->matchesPattern($doc_pattern);
As you can see, I need to install the XML::LibXML::Pattern module. Here is the log info during the installation process of XML::LibXML::Pattern.
It seems to have only installed the XML::LibXML, not the XML::LibXML::Pattern? Did I miss something?
Oh, I needed the XML::LibXML::Reader module too, and its installation process went smooth.

XML::LibXML::Pattern is a package populated by the XML::LibXML module (XML/LibXML.pm) of the XML-LibXML distribution, so the correct distribution was indeed installed.
There's no XML/LibXML/Pattern.pm, so use XML::LibXML::Pattern; will fail. As the documentation shows, you need to use use XML::LibXML;.
