如何从 xml <Any> 元素中获取值？

问题描述 投票：0回答：1

在我的 Biztalk Orchestration 设计器（表达式编辑器）中，我需要从名为 

<Any>
的元素中提取值。我创建了一个字符串变量并在该字段上执行了 xpath，但该变量结果为 null。

该元素在我的 xml 文件中被命名为“Base64Container”。

这是xpath：

vMyVariable = xpath(mKithResult.mmpBody, "/*[local-name()='Message' and namespace-uri()='http://www.kith.no/xmlstds/labsvar/2012-02-15']/*[local-name()='ServReport']/*[local-name()='RefDoc']/*[local-name()='Content'][1]/*[local-name()='Base64Container']");

问题出在这部分：

  /*[local-name()='Base64Container']");

如何从我的 xml 中名为 Base64Container 的元素中提取值？

这是我的 xml 文件：

    <?xml version="1.0" encoding="UTF-8"?>

我没有“Biztalk Orchestration Designer”，所以像下面这样的替代方案可能会有所帮助。

当您有 Notepad++ 时，通过 XML 插件，您可以执行以下操作：

Xml 工具/评估 XPath 表达式，表达式为：

//x:Base64Container

或者，第二个选项，表达式：

/x:Message/x:ServReport/x:RefDoc/x:Content/x:Base64Container
