Every XML entry is represented via a record with tag, attribute and content fields. To represent different types of entries different values are written to this fields:
- 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>"}.
Unlike to xml command all null values are always present and text is never represented via plain string. This way content of every tag is always a table and is easier to parse
