Nokogiri is not a mandatory dependency for this plugin, so this should
work without it.
Currently, we need to install Nokogiri manually.
Otherwise, the following LoadError occurs:
<internal:/path/to/rubygems/core_ext/kernel_require.rb>:88:in `require': cannot load such file -- nokogiri (LoadError)
from <internal:/path/to/rubygems/core_ext/kernel_require.rb>:88:in `require'
from /path/to/gems/fluent-plugin-windows-eventlog-0.8.3/lib/fluent/plugin/bookmark_sax_parser.rb:1:in `<top (required)>'

Although it's better than depending nokogiri mandatory, it might be better to do more something here.
- Try REXML::Parsers::StreamParser
- Match not only
Channelbut also<BookmarkList>and</BookmarkList>to check the file isn't truncated.
In addition, I've noticed that winevt_c should check GetLastError() when it fails on EvtCreateBookmark(): https://github.com/fluent-plugins-nursery/winevt_c/blob/9dd9c81432b1e0180c7abc19de8415bb42db2e49/ext/winevt/winevt_bookmark.c#L93

We can consider making this work with
rexmlifNokogiriis not available.On the other hand, this PR is based on the idea that we don't have to go that far now.
At least, we should be able to judge if the bookmark is empty or not for #40.
We wouldn't necessarily need an XML parser for this.
(Of course it is preferable to parse it properly, but it wouldn't be as much to make Nokogiri a mandatory dependency just for that purpose.)
