Xml AWS route53正在删除资源集

我正在使用亚马逊推荐的dnscurl.pl，以便从route53中删除记录集。我遇到了一个我无法理解的错误。路由53响应错误：InvalidInput。消息：无效的XML；cvc elt.1:找不到元素“ChangeResourceRecordSetRequest”的声明

    <ErrorResponse xmlns="https://route53.amazonaws.com/doc/2012-02-29/">
      <Error><Type>Sender</Type><Code>InvalidInput</Code>
        <Message>Invalid XML ; cvc-elt.1: Cannot find the declaration of element 'ChangeResourceRecordSetsRequest'.</Message>
      </Error><RequestId>51c5c1de-c246-11e2-b977-934c36c18aa7</RequestId>        
    </ErrorResponse>

我的要求如下：

    dnscurl.pl --keyname my_key_name -- -s -H "Content-Type: text/xml; charset=UTF-8" -X POST --upload-file /tmp/tmp.qEYXdPVpFh https://route53.amazonaws.com/2012-02-29/hostedzone/xxxxxxxxxx/rrset

正在使用的xml文件是：

    <?xml version="1.0" encoding="UTF-8"?>
      <ChangeResourceRecordSetsRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12">
        <ChangeBatch>

正在删除staging.mysite.com的记录。2013年5月21日星期二17:37:52 UTC
DELETEstaging.mysite.com.axxxxxxxxxawseb-e-s-awsebloa-xxxxxxxx-xxxxxxx.us-east-1.elb.amazonaws.com。
删除ec2.staging.mysite.com.CNAME300ec2-xx.xx.xx.xx.compute-1.amazonaws.com

我找不到有关XML无效原因的任何信息。它检查所有XML验证程序。你知道怎么做吗

谢谢

尝试更改此选项：

<ChangeResourceRecordSetsRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12">

为此：

<ChangeResourceRecordSetsRequest xmlns="https://route53.amazonaws.com/doc/2012-12-12/">

我注意到您没有关闭：

</ChangeResourceRecordSetsRequest>
