我有一个 XML 查询的问题，我已经咀嚼了一段时间，但我无法克服它。我有：

  1. 创建了指向 ASMX Web 服务的共享 XML 数据源。
  2. 尝试使用 XML 查询创建数据集。

a) 如果我获取 Web 服务结果并使用 运行 XML 查询<XMLData>，那么我会得到一个结果集。显然查询不包括 Method 或 SoapAction 因为它直接访问<XMLData>.I 确实包括以下内容<ElementPath>outboundMessage/clinicLocationPanel/clinicLocation</ElementPath>.

b）如果我排除<XMLData>并包括 SoapAction 和 Method 并使用通配符，<ElementPath IgnoreNamespaces="true">*</ElementPath>那么我会得到一个结果集。

c) 但是，如果我尝试用 做“b)” <ElementPath>outboundMessage/clinicLocationPanel/clinicLocation</ElementPath>，那么它不会返回任何结果（一堆空行）。

“a)”示例：

<Query xmlns="http://sample.org/pcp">
  <XmlData>
<?xml version="1.0" encoding="UTF-8"?>
<outboundMessage xmlns="http://sample.org/pcp">
  <messageType>ADT</messageType>

    </clinicLocation>
  </clinicLocationPanel>
</outboundMessage>
  </XmlData>
<ElementPath>outboundMessage/clinicLocationPanel/clinicLocation</ElementPath>
</Query>

旁注：当我使用 SQL Profiler 时，我看到参数被正确传递，如果从 SQL Profiler 获取相同的查询并执行它，它将返回 XML。我认为我的问题可能与<Method>or<ElementPath>标签有关。
