# toXml method

String toXml()

Renders the entire node, including its children, into an XML string.

## Implementation

    String toXml() {
      final decl = isDeclaration ? '?' : '';
      if (children.isEmpty) {
        if (text != null && text!.isNotEmpty) {
          final attrString = attributes.isEmpty ? '' : ' ${renderAttributes()}';
          return '<$tag$attrString>$text</$tag>';
        } else {
          return '<$decl$tag ${renderAttributes()}${closeTag ? " />" : "$decl>"}';
        }
      } else {
        final childXml = children.map((child) => child.toXml()).join();
        final xml = '<$decl$tag ${renderAttributes()}$decl>$childXml';
        return xml + (closeTag ? '</$tag>' : '');
      }
    }
