发送xml文件出现 org.xmlpull.v1.XmlPullParserException: processing instruction can not have PITarget with reserveld xml name (position: START_DOCUMENT seen \n <?xml ... @2:13) \nprocessing instruction can not have PITarget with reserveld xml name (position: START_DOCUMENT seen \n <?xml ... @2:13) </ows:ExceptionText>\n问题

在发送xml请求的时候，返回的是如下图所示的情况。

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<ows:ExceptionReport
    xmlns:xs=\"http://www.w3.org/2001/XMLSchema\"
    xmlns:ows=\"http://www.opengis.net/ows\"
    xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" version=\"1.0.0\" xsi:schemaLocation=\"http://www.opengis.net/ows http://localhost:8080/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd\">\n
    
    <ows:Exception exceptionCode=\"NoApplicableCode\">\n
        
        <ows:ExceptionText>org.xmlpull.v1.XmlPullParserException: processing instruction can not have PITarget with reserveld xml name (position: START_DOCUMENT seen \\n      &lt;?xml ... @2:13) \nprocessing instruction can not have PITarget with reserveld xml name (position: START_DOCUMENT seen \\n      &lt;?xml ... @2:13) </ows:ExceptionText>\n
    
    </ows:Exception>\n

</ows:ExceptionReport>

解决方法

看一下我们发送的xml请求

<?xml version="1.0" ?>
<wfs:Transaction
   version="2.0.02.0.2"
   service="WFS"
   xmlns="http://www.someserver.example.com/myns"
   xmlns:fes="http://www.opengis.net/fes/2.0"
   xmlns:wfs="http://www.opengis.net/wfs/2.0"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.opengis.net/wfs/2.0
                       http://schemas.opengis.net/wfs/2.0.02.0/wfs.xsd">
   <wfs:Update typeName="BuiltUpA_1M">
      <wfs:Property>
         <wfs:ValueReference>population</wfs:ValueReference>
         <wfs:Value>4070000</wfs:Value>
      </wfs:Property>
      <fes:Filter>
         <fes:ResourceId rid="BuiltUpA_1M.10131"/>
      </fes:Filter>
   </wfs:Update>
</wfs:Transaction>

可以看到xml文件的内容并没有进行闭合

可以删除首行解决

<?xml version="1.0" ?>
