问题描述

你怎么能用substring或其他方法读取我的xml字符串。

i想读帅哥，仍然可以制作和SuperHandsome字符串

Hi how can i read my xml string using substring or other methods.
i want to read "Handsome", "Still Can Make it" and "SuperHandsome" string

<male>
<gender>Tommy = Handsome</gender>
<gender>Jackson = Handsome</gender>
<gender>David = SuperHandsome</gender>
<gender>Chris = Still Can Make it</gender>
</male>

Try
 Using reader As XmlReader = XmlReader.Create("C:\Users\Desktop\Boy.xml")
   While reader.Read()
     If reader.IsStartElement() Then
        Select Case reader.Name
          Case "gender"
            If reader.Read() Then
             If reader.Value.Trim() <> Nothing Then
                boyname += reader.Value.Trim() & Environment.NewLine
             End If
            End If

推荐答案

你的XML做得不好。如果您的XML看起来像这样会更好：

Your XML is poorly done. It would have been better had your XML looked something like this:

<persons gender="male">
    <person name="Tommy" value="Handsome" />
    <person name="Jackson" value="Handsome" />
    <person name="David" value="SuperHandsome" />
    <person name="Chris" value="Still can make it" />
</persons>

这样就不需要解析其中包含的字符串了。



但是，这取决于你。使用 myStringValue .IndexOf（=）获取=字符的位置。然后，您可以使用该位置值来获取=字符左侧所有内容的 SubString（），并再次作为获取其后所有内容的起点。



阅读这两种方法及其工作方式这里 [ ^ ]。

That way there's no need to do any parsing of a string contained within.

But, that's up to you. Get the position of the "=" character with myStringValue.IndexOf("="). You can then use that position value to get the SubString() of everything to the left of the "=" character and again as a starting point to get everything after it.

Read up on the two methods and how they work here[^].
