As long as the ABNF fragments are in sourcecode elements with a correct type attribute, the ABNF file can be rebuilt like this:

xmllint --nocdata --xpath "//sourcecode[@type='abnf']/text()" file.xml >file.abnf

The name attribute can also be used to extract only the fragments that belong to one specific file.
