getText static method

Implementation

static String? getText(XmlNode? node, {bool innerXmlAsText = false}) {
  // node is text or cdata
  if (node?.nodeType == XmlNodeType.TEXT ||
      node?.nodeType == XmlNodeType.CDATA) return node?.value;

  // return node inner xml as text

            (child is XmlCDATA || child is XmlText || child is XmlComment)
                ? false
                : true) ==
        null);
    var text = isText ? node?.innerText.trim() : node?.innerXml.trim();
    //text = text?.replaceAll('\r', '').replaceAll('\t', '').replaceAll('\n', '').trim();
    return text;
  }

  // traverse child nodes
  if ((node?.children.isNotEmpty == true)) {
    String? text;
    for (XmlNode n in node!.children) {
