Tag entry: {tag: <tag name> attrs: {<attr name>: "<string value>" ...} content: [<entries>]}
Comment entry: {tag: '!' attrs: null content: "<comment string>"}
Processing instruction (PI): {tag: '?<pi name>' attrs: null content: "<pi content string>"}
Text: {tag: null attrs: null content: "<text>"}.
