partial-xml-stream-parser/dist/src/parser-setup.js

A lenient XML stream parser for Node.js and browsers that can handle incomplete or malformed XML data, with depth control, CDATA support for XML serialization and round-trip parsing, wildcard pattern support for stopNodes, and CDATA handling within stopNo
