I'm trying to do the following.

我试着做下面的事情。

OMElement soapEnvelope = new StAXOMBuilder(soapEnvelopXMLFilePath).getDocumentElement();
OMElement firstElement = soapEnvelope.getFirstElement().getFirstElement();

Then i iterate through the child elements of the firstElement like this.

然后像这样迭代firstElement的子元素。

Iterator<OMElement> items = firstElement.getChildren();
while (items.hasNext()) {
    OMElement element = items.next();
    // ....do some processing here...
}

But when i try to execute this following class cast exception occurs.

但是当我尝试执行下面的类强制转换时，会发生异常。

java.lang.ClassCastException: org.apache.axiom.om.impl.llom.OMTextImpl cannot be cast to org.apache.axiom.om.OMElement 

The error occurs when items.next() is assigned to element OMElement object.

当项.next()被分配给元素OMElement对象时发生错误。

Any idea why i'm getting this exception? I can't figure out any mismatch.

知道我为什么会有这个例外吗?我不知道有什么不匹配。

These are the contents of my sample xml file.

这些是我的示例xml文件的内容。

                </ns:HOSTS>
            </ns:MONITOR>
        </soapenv:Body>

Thanks.
