在我的wix安装程序中，我有一个组件，它只是为web.config添加了一个wcf绑定。现在，当基本产品安装时启用了不同的wcf服务，我的安装程序将不会将其绑定信息添加到web.config。
我很确定这是因为web.config中的其他服务已经有一个wsHttpBinding元素。
所以我的问题是我可以在VerifyPath中使用任何路径吗？喜欢而不是检查是否存在根元素，我可以检查其下的嵌套元素是否具有我要查找的名称？
以下是我的XmlConfig语句供参考：

基本上VerifyPath使用XPATH查询，因此如果您编写正确的查询来选择属性，您应该能够比较它或检查
要在web.config中选择条目“service1binding”，我们将使用以下XPATH查询
<wsHttpBinding>
<binding name="service1binding">
XPATH查询
<强> "/configuration/system.serviceModel/bindings/wsHttpBinding/binding[@name='service1binding']"
ABOVE XPATH查询未针对WIX格式化，您无法按原样使用
请注意，VERIFYPATH是一个格式化字段，因此必须转义XPath中的方括号。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，则必须通过在此属性中将它们加倍来转义它们。该字符串首先由MSI格式化，结果将作为XPath使用。
