（最初标题为“运行时错误91 - 未设置XML对象变量。一半时间工作？”）
我有一个VB脚本，用于打开XML文档并从中提取一些信息。

如果我在A列中有一个地址列表，这个宏可以很好地运行许多地址......但是，在某些点之后（似乎是i＆gt; = 28时），尝试时设置county = countyNodes(i).NodeValue我收到错误：
对象变量或未设置块。
为什么？对于任何其他内容（latitude，longitude，altAddress），它不会执行此操作。与实际的XML有关...
感谢您的任何想法！
编辑：这是一个XML页面，加载后会导致错误：Link
每个位置都有administrative_area_level_2个标签
EDIT2：
好的，我认为当给出多个地址时会出现问题。在我的A1和A2中，我有：
1600 Pennsylvania
1600 Pennsylvania Ave, Washington DC
因此，当Google查找1600 Pennsylvania时，有30种可能的匹配。代码运行时没有问题UNTIL最终的第30个地址（“宾夕法尼亚州，巴拿马，OK 74951，美国”），来自this XML page。
所以，我认为错误已经缩小，只有当找到多个匹配时才会发生在最后一个地址上。

答案 0 :(得分：2)
以下是我认为你需要解决的问题。首先，使用<result>检索所有selectNodes()个节点：
Set objResultNodes = oXMLFile.selectNodes("/GeocodeResponse/result")
然后，迭代这些<result>节点中的每一个，并使用带有相对路径的selectSingleNode()来查找与您的查询匹配的每个<result>下方的子项。请注意我们如何从geometry/...开始 - 基于现有节点（<result>）的相对路径。
For Each n In objResultNodes
Set lat = n.selectSingleNode("geometry/location/lat")
Set lng = n.selectSingleNode("geometry/location/lng")
' ... your other searches
If Not lat Is Nothing Then .Range("B" & i).Value = lat.Text
If Not lng Is Nothing Then .Range("C" & i).Value = lng.Text
' ... your other searches
Next
我就是这样做的。这样，您可以将每个<result>作为一个单元进行处理，并且能够判断何时administrative_area_level_2或其他某些子节点不可用。
