HarmonyOS鸿蒙Next中使用convertxml.ConvertXML解析xml字符串出现问题

HarmonyOS鸿蒙Next中使用convertxml.ConvertXML解析xml字符串出现问题 我在使用convertxml.ConvertXML 解析xml字符串时出现了一个属性未解析问题：

let options: convertxml.ConvertOptions = {
    trim: false,
    declarationKey: "_declaration",
    instructionKey: "_instruction",
    attributesKey: "_attributes",
    textKey: "_text",
    cdataKey: "_cdata",
    doctypeKey: "_doctype",
    commentKey: "_comment",
    parentKey: "_parent",
    typeKey: "_type",
    nameKey: "_name",
    elementsKey: "_elements"
}

const xmlStr = "<iq from=\"mk\" to=\"client\" id=\"0026b9fffe2f2112-00004c58-00003c98-e7a3f262c613f14a-8aa815a5\" type=\"set\"><query xmlns=\"jabber:connect:channel\"><channelId>0026b9fffe2f2112-00004c58-00003c98-e7a3f262c613f14a-8aa815a5</channelId></query></iq>"
let conv: convertxml.ConvertXML = new convertxml.ConvertXML();
let result: object = conv.fastConvertToJSObject(xmlStr, options);
Logger.debug("xml 转对象=>" + JSON.stringify(result))

结果：
xml 转对象=>{"_declaration":{"_attributes":{"version":"1.0"}},"_elements":[{"_type":"element","_name":"iq","_attributes":{"from":"mk","to":"client","id":"0026b9fffe2f2112-00004c58-00003c98-e7a3f262c613f14a-8aa815a5","type":"set"},"_elements":[{"_type":"element","_name":"query","_parent":"iq","_elements":[{"_type":"element","_name":"channelId","_parent":"query","_elements":[{"_type":"text","_text":"0026b9fffe2f2112-00004c58-00003c98-e7a3f262c613f14a-8aa815a5"}]}]}]}]}

代码如上，其中在 query 节点中的属性xmlns没有解析到。请教大家如何破局？
