Overview

Tree-free scan stand-in for the builder protocol. Records recover errors and accumulates an attribute-name-order signature (element open/close tokens plus each non-xmlns attribute name in document order); content itself is ignored — the digest gate covers it. The verbose lane compares the two sides' signatures to prove the absence of the two digest-invisible report entries: informative attribute-order DiffNodes and the SAX-lane parse-error banner (issue #130).

Instance Method Details

#cdata(_string) ⇒ Object

The builder protocol the SAX drivers forward to is cdata (MoxmlDriver#on_cdata and NokogiriDriver#cdata_block both call builder.cdata); the nokogiri-style name here made every CDATA-bearing probe raise NoMethodError under the flipped leptris SAX engine.
