Soap Web services?

[Ohpizarro]

replace XmlElement inside an XmlDocument.
I use it to build xml for SOAP webservices

To solve it I am parameterizing through XmlNode. It is right?
variable tipoDocumento is an array with XmlElement or must be excluded if it contains no elements.

XmlNode _segmento;
if (tipoDocumento == null) {
_segmento = XmlComment('Vacio');
} else {
_segmento = XmlElement(
name: 'wsn:tipoDocumento',
children: [
XmlElement(
name: 'java:JavaLangstring',
children: [
XmlText('$tipoDocumento'),
],
)
],
);
}
