关于dom4j解析xml

 

一：相关jar包

dom4j-1.6.1.jar

二：用例xml文件

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Header>
        <OGHeader transactionID="000040" timeStamp="2004-01-14T03:58:44.946875+08:00"

            <Origin entityID="TAOBAO" systemType="MAINTAIN" />
            <Destination entityID="ORS" systemType="ORS" />
        </OGHeader>
    </soap:Header>
    <soap:Body>
        <CancelBookingResponse xmlns:c="http://webservices.micros.com/og/4.3/Common/"
            xmlns:hc="http://webservices.micros.com/og/4.3/HotelCommon/" xmlns="http://webservices.micros.com/ows/5.1/Reservation.wsdl">
            <Result resultStatusFlag="FAIL">
                <c:Text>
                    <c:TextElement>BOOKING NOT FOUND</c:TextElement>
                </c:Text>
                <hc:GDSError errorCode="15">BOOKING NOT FOUND</hc:GDSError>
            </Result>
            <ImageItems>                                    
                <ImageItem Category="6">
                    <ImageFormat><URL>www.baidu.com</URL></ImageFormat>
                    <Description Caption="百度" />
                    <TPA_Extensions>
                        <TPA_Extension>
                            <Extension Name="Property">
                                <Item Key="IsMain" Value="true" />
                            </Extension>
                        </TPA_Extension>
                    </TPA_Extensions>
                </ImageItem>
                <ImageItem Category="6">
                    <ImageFormat><URL>http://www.google.cn/</URL></ImageFormat>
                    <Description Caption="谷歌" />
                </ImageItem>
            </ImageItems>
        </CancelBookingResponse>
    </soap:Body>
</soap:Envelope>

 

三：解析

注：可能有的小白不知道如果获取节点，so，you can：

for (Iterator<Element> i = rootElement.elementIterator(); i.hasNext();) {
　　Element element = i.next();
　　System.out.println("节点名称：" + element.getName());
}

结果：

节点名称：Header
节点名称：Body

                        Element TPA_Extension = TPA_Extensions.element("TPA_Extension");
                        Element Extension = TPA_Extension.element("Extension");
                        if (Extension != null && "Property".equalsIgnoreCase(Extension.attributeValue("Name"))) {
                            Element Item = Extension.element("Item");
                            if (Item != null && "IsMain".equals(Item.attributeValue("Key"))) {
                                if (Item.attributeValue("Value") != null && "true".equals(Item.attributeValue("Value"))) {
                                    System.out.println("IsMain："+Item.attributeValue("Value"));
                                }
                            }
                        }
                    }else {
                        System.out.println("IsMain：NO");
                    }
                }
            }
        }
    }
}

 

结果：
