【问题描述】：

在我的 wix 安装程序中，我有一个组件，它只是将 wcf 绑定添加到 web.config。现在，当安装基础产品并启用不同的 wcf 服务时，我的安装程序不会将其绑定信息添加到 web.config。

我很确定这是因为 web.config 中已经有一个用于其他服务的 wsHttpBinding 元素。

所以我的问题是我可以在我的 VerifyPath 中使用任何路径吗？除了检查该根元素是否存在之外，我还可以检查其下的嵌套元素是否具有我要查找的名称吗？

以下是我的 XmlConfig 语句供参考：

【参考方案1】：

VerifyPath 基本上使用 XPATH 查询，因此如果您编写正确的查询来选择属性，您应该能够比较或检查它

要在 web.config 中选择一个条目“service1binding”，我们将使用以下 XPATH 查询

<wsHttpBinding>
 <binding name="service1binding">

XPATH 查询

"/configuration/system.serviceModel/bindings/wsHttpBinding/binding[@name='service1binding']"

上述 XPATH 查询未针对 WIX 进行格式化，您无法按原样使用它

请注意，VERIFYPATH 是一个格式化的字段，因此必须对 XPath 中的方括号进行转义。此外，XPath 允许使用反斜杠来转义字符，因此如果您打算包含文字反斜杠，则还必须通过在此属性中将它们加倍来转义它们。字符串先由 MSI 格式化，结果作为 XPath 消费。

谢谢，这是我想知道的。
