我需要在包含唯一字符串的XML文件中搜索字符串
<CSVName Value="standard.csv" />
此值在&#34; standard.csv&#34;之间变化。和&#34; non-standard.csv&#34;。
我正在使用VBScript搜索&#34; standard.csv&#34;或&#34; non-standard.csv&#34;。如果匹配&#34; standard.csv&#34;它会回应我&#34;这是标准的&#34;,如果匹配&#34;非标准.sv&#34;它会回应我&#34;这是非标准的&#34;。
当点击按钮时,这是我的HTA功能的一部分,我不知道如何制作reg exp模式以匹配&#34; A&#34;或&#34; B&#34;然后相应地回应每一个。

YOU ARE CURRENTLY IN STANDARD CSV MODE <p>
<input id=runbutton class="button" type="button" value="CURRENT MODE" name="db_button" onClick="RUCURRENTMODE" style="width: 170px"><p>

要回答当前问题,Pattern
属性需要一个字符串,因此您必须更改此内容:
objRegEx.Pattern = (?:"standard.csv"|"non-standard.csv")
进入这个:
objRegEx.Pattern = "(?:standard\.csv|non-standard\.csv)"
您甚至可以将表达式简化为:
objRegEx.Pattern = "(?:non-)?standard\.csv"
但是,显然你有一个XML文件,所以你首先要shouldn't be using regular expressions for this。使用实际的XML解析器来提取信息:
Set xml = CreateObject("Msxml2.DOMDocument.6.0")
xml.async = False
xml.load "C:\aaa\settings.xml"
If xml.ParseError Then
MsgBox xml.ParseError.Reason
self.Close() 'or perhaps "Exit Sub"
End If
For Each n In xml.SelectNodes("//CSVName")
Select Case n.Attributes.GetNamedItem("Value").Text
Case "standard.csv" : MsgBox "This is standard."
Case "non-standard.csv" : MsgBox "This is non-standard."
Case Else : MsgBox "Unexpected value."
End Select
Next
