使用c#获取XDocument中同一级别的所有XML属性值

Question

我有以下 XML

我需要的是从 XDocument XML 获取同一级别的 XML 中每个“级联实体”部分的“条件”属性的所有值

在这种情况下，结果应该是

clm_bankingrelationship.clm_agreementid clm_bankingrelationship.clm_bankingrelationshipid

我已经尝试了各种方法，但要么获得所有现有后代（级别）的所有值，要么只获得第一个。我需要的是同一级别的第一个元素的值。

任何提示都非常感谢。

谢谢

这里是 XML：

<rootentity name='clm_bankingrelationship'>
    <cascadingentities>
        <cascadingentity name='clm_agreement'>
            <fetchXML>
                <fetch distinct='true'>
                    <entity name='clm_agreement' >

                        <filter type='and'>

您可以使用 XPath 来获取这些值：

var xml = XDocument.Load(PATH_TO_XML);
var conditions = xml.XPathEvaluate("rootentity/cascadingentities/cascadingentity/" 
                                 + "fetchXML/fetch/entity/filter/condition");
var values = ((IEnumerable<object>)conditions).OfType<XElement>()
                 .Select(e => e.Attribute("value").Value.Trim('{', '}'));
