livery_s3_xml (livery_s3 v0.1.0)

View Source

Minimal XML parsing for S3 responses.

S3 returns XML for bucket/object listings, versioning, multipart, batch delete, and error bodies. Rather than pull in the xmerl record headers, this parses into a light {Tag, Attrs, Children} tree via xmerl_sax_parser and offers a few navigation helpers (child/2, children/2, text/2). Tags are local names as binaries; namespaces are dropped (S3 uses a single default namespace).
