java - 如何解决 ExpatParser$parseException

Question

我从我的 .net Web 服务得到以下结果

<?xml version="1.0" encoding="utf-8" ?> 
- <DataTable xmlns="http://www.mkttech.in/">
- <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

  </DataTable>

我正在使用 SoapObject 来接收此响应。接下来我使用 xmlpullparser 解析它。我关注了以下Tutorial

但是执行 nextTag() 时出现以下异常

org.xmlpull.v1.XmlPullParserException:解析文档时出错。 (位置:第 -1 行，第 -1 列)由以下原因引起:org.apache.harmony.xml.ExpatParser$ParseException:在第 1 行第 7 列:格式不正确(无效 token )

我对 android 和 java 都是新手。我真的需要帮助。提前致谢!

<?xml version="1.0"... 之前不能有空格.使用此在线应用程序查看 XML/XSD Validation
