如何使用pl/sql解析具有href标签的soap响应

Question

我想解析下面的肥皂响应。问题出在 tag1 中，它指向一个名为 id1 的 href 链接。所以我们要到id1的response去获取value。

还有一件事是这个soap响应值是改变每个请求中的顺序。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
    <ns1:getBlock soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://diamondip.com/ipcontrol/ws/">
        <getBlockByIpAddressReturn href="#id0"/>
    </ns1:getBlock>

<multiRef id="id0" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns2:WSGenericBlock" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns2="http://service.ipcontrol.diamondip.com">
    <tag1 href="#id1"/>      
    <tag2 soapenc:arrayType="soapenc:string[1]" xsi:type="soapenc:Array">
        <item xsi:type="soapenc:string">Container1</item>
    </tag2>  
    <tag3 xsi:type="xsd:dateTime">2013-02-01T06:45:32.000Z</tag3>
    <tag4 soapenc:arrayType="soapenc:string[4]" xsi:type="soapenc:Array">
        <item xsi:type="soapenc:string">uf1=221805</item>
        <item xsi:type="soapenc:string">uf2=34531</item>
    </tag4> 
    <tag5 href="#id2"/> 
</multiRef>   
<multiRef id="id1" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="xsd:boolean" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">false</multiRef>
<multiRef id="id2" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" lowestSetBit="3" xsi:type="soapenc:integer" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">8</multiRef>
</soapenv:Body>
</soapenv:Envelope>

也许这可以给你一个开始（这并不完美，我知道...）
