我想阅读DivaURI键的值,但我不能这样做。我尝试了很多东西。我想要达到userProperties子类别。最后想要读取DivaURI键的值。
这是一个类别XElement:
<CfgDN>
<DBID value="6422" />
<switchDBID value="110" />
<tenantDBID value="101" />
<type value="4" />
<number value="3401" />
<loginFlag value="1" />
<registerAll value="2" />
<groupDBID value="0" />
<trunks value="0" />
<routeType value="1" />
<state value="1" />
<userProperties>
<list_pair key="__ROUTER__">
<str_pair key="BackupVDN" value="3921" />
<str_pair key="DivaIVRProfile" value="TS_IVR_Profile" />
<str_pair key="DivaURI" value="I WANT TO READ THIS VALUE!" />
</list_pair>
<list_pair key="default">
<str_pair key="monitor_calls" value="true" />
</list_pair>
<list_pair key="TServer">
<str_pair key="default-dn" value="43921" />
<str_pair key="router-timeout" value="5" />
</list_pair>
<list_pair key="URS_PROD_01">
<str_pair key="Loaded" value="07/25/2012 01:57 PM" />
<str_pair key="Loaded by" value="default" />
<str_pair key="strategy" value="GVP Diva Main Strategy TEST" />
<str_pair key="strategy0x65" value="GVP Diva Main Strategy TEST" />
</list_pair>
<list_pair key="URS_PROD_01_81">
<str_pair key="Loaded" value="09/15/2012 06:03 AM" />
<str_pair key="Loaded by" value="default" />
<str_pair key="strategy" value="GVP Diva Main Strategy PROD" />
<str_pair key="strategy0x65" value="GVP Diva Main Strategy PROD" />
</list_pair>
<list_pair key="URS_PROD_02">
<str_pair key="Loaded" value="07/25/2012 01:57 PM" />
<str_pair key="Loaded by" value="default" />
<str_pair key="strategy" value="GVP Diva Main Strategy TEST" />
<str_pair key="strategy0x65" value="GVP Diva Main Strategy TEST" />
</list_pair>
<list_pair key="URS_PROD_02_81">
<str_pair key="Loaded" value="09/15/2012 06:03 AM" />
<str_pair key="Loaded by" value="default" />
<str_pair key="strategy" value="GVP Diva Main Strategy PROD" />
<str_pair key="strategy0x65" value="GVP Diva Main Strategy PROD" />
</list_pair>
</userProperties>
<name value="3401" />
<useOverride value="2" />
<switchSpecificType value="1" />
<siteDBID value="0" />
<contractDBID value="0" />
</CfgDN>
还有一些XElements没有任何userProperties类别:
<CfgDN>
<DBID value="6409" />
<switchDBID value="101" />
<tenantDBID value="101" />
<type value="19" />
<number value="3351" />
<loginFlag value="1" />
<registerAll value="2" />
<groupDBID value="0" />
<trunks value="0" />
<routeType value="1" />
<state value="1" />
<name value="3351_Avaya" />
<useOverride value="2" />
<switchSpecificType value="1" />
<accessNumbers>
<CfgDNAccessNumber>
<switchDBID value="110" />
<number value="41451" />
</CfgDNAccessNumber>
<CfgDNAccessNumber>
<switchDBID value="113" />
<number value="41451" />
</CfgDNAccessNumber>
</accessNumbers>
<siteDBID value="0" />
<contractDBID value="0" />
</CfgDN>
我试图像这样联系他们:
IEnumerable<XElement> enumElem = from p in xdoc.Descendants("DivaURI") where p.Parent.Name.Equals("userProperties") select p;
foreach (XElement child in enumElem)
{
//XElement elem = enumElem.Current;
if (child.Name.LocalName == "DivaURI")
{
...
}
}
有什么建议吗?
答案 0 :(得分:1)
请注意,"DivaURI"
是key
属性的值,而不是元素名称。
假设只有一个元素的密钥等于"DivaURI"
,这是一种可能的方法:
XElement str_pair =
xdoc.Descendants("str_pair")
.FirstOrDefault(o => (string)o.Attribute("key") == "DivaURI");
if(str_pair != null)
Console.WriteLine((string)str_pair.Attribute("value"));
更新:
更新了处理默认命名空间和多个<str_pair>
元素的代码,如注释中所述:
XNamespace d = "blabla/Configuration/ConfServer/2005/";
IEnumerable<string> result = from p in xdoc.Descendants(d+"str_pair")
where (string)p.Attribute("key") == "DivaURI"
select (string)p.Attribute("value");
答案 1 :(得分:0)
试试这个:
var getValue = from a in xdoc.Descendants("CfgDN").Elements("userProperties").Elements("list_pair").Elements("str_pair")
where a.Attribute("key").Value == "DivaURI"
select a.Attribute("value").Value;
输出:
I WANT TO READ THIS VALUE!
