c# – xs：element的最近祖先的xs：documentation节点

概述我有一个wsdl文档,其摘录如下所示…… <xs:complexType name="CustomerNameType"> <xs:annotation> <xs:documentation>Structure for customer name</xs:documentation> </xs:annotation> <xs:sequence> <xs:element 我有一个wsdl文档,其摘录如下所示……

<xs:complexType name="CustomernameType">  <xs:annotation>    <xs:documentation>Structure for customer name</xs:documentation>  </xs:annotation>  <xs:sequence>    <xs:element name="Fullname" minOccurs="0">      <xs:simpleType>        <xs:restriction base="xs:string">          <xs:maxLength value="60"/>        </xs:restriction>      </xs:simpleType>    </xs:element>    <xs:element name="Forenames" minOccurs="0">      <xs:simpleType>        <xs:restriction base="xs:string">          <xs:maxLength value="60"/>        </xs:restriction>      </xs:simpleType>    </xs:element>  </xs:sequence></xs:complexType>

我知道xs：element / @ name,我想得到最近的xs：documentation元素.

使用上面的示例,我知道xs：element / @ name =“Fullname”,我想从最近的xs：documentation节点获取文本“客户名称的结构”！

我已经尝试更改我在stackoverflow(和其他站点)上找到的一些示例,但它们都不起作用.典型：0).

干杯.

感谢您回答…希望这会有用……

public static string DecryptStupIDCapsError(string sOriginalErrorMessage){    string sProblem = sOriginalErrorMessage.Substring(sOriginalErrorMessage.IndexOf("---> System.Xml.Schema.XmlSchemaException: ") + "---> System.Xml.Schema.XmlSchemaException: ".Length);    sProblem = sProblem.Substring(0,sProblem.IndexOf("An error occurred"));    string sElementname = sProblem.Substring(sProblem.IndexOf(":") + 1);    sElementname = sElementname.Substring(sElementname.IndexOf(":") + 1);    sElementname = sElementname.Substring(0,sElementname.IndexOf("'"));    Xmldocument xd = new Xmldocument();    xd.LoadXml(PropertIEs.Resources.ServiceRequest_Service_74b1);    XmlnamespaceManager xnsm = new XmlnamespaceManager(xd.nametable);    XPathdocument x = new XPathdocument(new StringReader(PropertIEs.Resources.ServiceRequest_Service_74b1));    XPathNavigator foo = x.CreateNavigator();    foo.MovetoFollowing(XPathNodeType.Element);    IDictionary<string,string> whatever = foo.GetnamespacesInScope(XmlnamespaceScope.All);    foreach (keyvaluePair<string,string> xns in whatever)    {        xnsm.Addnamespace(xns.Key,xns.Value);    }    XmlNodeList xnl = xd.SelectNodes("//xs:element[@name='" + sElementname + "']",xnsm);    StringBuilder sb = new StringBuilder();    sb.Appendline("CAPS has reported a (cryptic) error whilst valIDating the data you entered.");    sb.Appendline();    sb.Appendline("The following summary should enable you to determine what has caused the '" + sElementname + "' data to be invalID.");    sb.Appendline("----------");    string sLast = string.Empty;    foreach (XmlElement xe in xnl)    {        StringBuilder sbLast = new StringBuilder();        XmlElement xedocumentation = (XmlElement)xe.Ownerdocument.SelectSingleNode("(//xs:element[@name='" + sElementname + "']/ancestor-or-self::*/xs:annotation/xs:documentation)[last()]",xnsm);        if (xedocumentation.InnerText == sLast) continue;        sbLast.Appendline(sElementname + " AKA " + xedocumentation.InnerText + ": ");        sbLast.Appendline("has the following valIDation rules:");        Xdocument xdoc = Xdocument.Parse(xe.OuterXml);        sbLast.Appendline(xdoc.ToString());        sbLast.Appendline("----------");        sb.Appendline(sbLast.ToString());        sLast = xedocumentation.InnerText;    }    return sb.ToString();}

基本上,sOriginalErrorMessage =一个XmlSchemaException.ToString(),而PropertIEs.Resources.ServiceRequest_Service_74b1是验证数据的wsdl.这个函数(缺少正则表达式！)为用户提供了更好的线索,告知导致验证失败的原因.与旧的XmlSchemaException相反.

再次感谢.

解决方法 以下XPATH将返回指定元素和所有父文档的文档.我认为亚历杭德罗的回答可能会返回一个兄弟的文档,在不同的模式中你可能不太感兴趣.

(//xs:element[@name='orderRequest']     /ancestor-or-self::*         /xs:annotation             /xs:documentation)[last()]
