替换网页文本中的空格的怪异问题 [英] weird problem with replacing space in text from a web-page

问题描述

您好，我有两行文字，在实际文字之前有较长的空格(更像是14-15空格).我已经尝试过简单的替换来拆分和合并，但是没有任何效果.我也尝试过修剪，最糟糕的是ascii给出的代码为32.但是没有任何效果.这是正文:

Hello i have two lines of text which have long space (more like 14-15 spaces) before the actual text. I have tried simple replace to split and merge but nothing is working. I have also tried trim and the worst thing is that ascii gives code of 32. But nothing works. here is the text :

                                      your heartburn symptoms
Certain foods, such as fat, chocolate, caffeine and alcohol can aggravate heartburn symptoms 1
Certain foods

(顺便说一句，它看起来并不像它.在我实际的richtextbox中，当我选择该空间时，它被选择为一个大的空间，例如标签，并且我也尝试替换vbtab但没有用)

我想要的是:

(BTW it''s not like it looks it is. In my actual richtextbox, when i select the space it gets selected as one big piece of space like a tab and i have also tried replacing vbtab but no use)

What i want is :

your heartburn symptoms
Certain foods, such as fat, chocolate, caffeine and alcohol can aggravate heartburn symptoms 1
Certain foods

相信我，我已经尝试了几乎7-8种不同的功能，但是现在我发疯了.我的逻辑之一:

Believe me i have tried almost 7-8 diffferent function but now iam going mad. one of my logic :

Dim lineArray As String() = rtfArticle.Lines

            For z As Integer = 0 To lineArray.Length - 1
                Dim w As String() = lineArray(z).Split(" ")
                MsgBox(lineArray(z))
                Dim tmp As String = ""

                For Each s34 As String In w
                    If (s34 <> " ") Then
                        temp = temp & " " & s34
                    End If
                Next
                lineArray(z) = temp
            Next

它完全弄乱了代码.对这个有任何想法吗?

it completely messes up the code. Any idea about this?

推荐答案

我要做的第一件事是查看您实际拥有的内容:使用string.ToCharArray函数作为字符数组，或者使用System.Text.Encoding.ASCII.GetBytes
以字节为单位
使用调试器在代码上断点并继续执行，或者将其输出到文件中，以便您可以离线分析它.除非您知道数据的真实外观，否则您只是在猜测解决方案.

The first thing I would do is look at what you actually have: Either as an array of characters using the string.ToCharArray function, or as bytes using System.Text.Encoding.ASCII.GetBytes

Either use the debugger to breakpoint on the code and follow it through, or output to a file so you can analyse it offline. Until you know what you data actually looks like, you are just guessing as to a solution.

Dim lineArray As String() = rtfArticle.Lines
For z As Integer = 0 To lineArray.Length - 1
    w(z) = lineArray(z).Trim()
