Here is a list of the types that will appear in the shared string table

here is the switch-case for the open-tags that currently exists in the parseSharedStrings function.

let text = null;
    let richText = [];
    let index = 0;
    let font = null;
    for await (const events of parseSax(iterateStream(entry))) {
      for (const {eventType, value} of events) {
        if (eventType === 'opentag') {
          const node = value;
          switch (node.name) {
            case 'b':
              font = font || {};
              font.bold = true;
              break;
            case 'charset':
              font = font || {};
              font.charset = parseInt(node.attributes.charset, 10);

the parseSharedStrings is not using the XForm Objects and we are missing several of the important xml tags.
