XML在VB.net ListView中重复两次值 [英] XML Repeating values twice in VB.net ListView

问题描述

我正在尝试使用以下代码将XML标签添加到ListView.我得到的结果是显示XML标记，但以重复的顺序

 ListView1.Columns.Add(" ， 100 ，Horizo​​ntalAlignment.Left)
     Dim  xpathDocument  As  XPathDocument
     Dim  xmlNavigator  As  XPathNavigator
    暗 xmlNodeIterator  As  XPathNodeIterator
    xpathDocument = 新建 XPathDocument(" )
    xmlNavigator = xpathDocument.CreateNavigator()
    xmlNodeIterator = xmlNavigator.选择(" )
    xmlNavigator = xmlNodeIterator.Current
    xmlNodeIterator = xmlNavigator.SelectDescendants(XPathNodeType.Element，真)

    同时 xmlNodeIterator.MoveNext
         ListBox1.Items.Add(xmlNodeIterator.Current.Name)
         ListView1.Items.Add(xmlNodeIterator.Current.Name)
    结束 同时

以下是我的XML
名称，价格，描述和卡路里这四个必须只出现一次，但它们重复两次.任何想法如何只显示一次

 <   xml    版本  ="    编码  ="    ? <   breakfast_menu  > 
  <  食物 > 
    <  名称 > 比利时华夫饼干<  /name  > 
    <  价格 >  $ 5.95 <  /price  > 
    <  描述 > 我们两个著名的比利时华夫饼，配以大量的真正的枫糖浆<  /description  > 
    <  卡路里 >  650 <  /卡路里 > 
  <  /food  > 
  <  食物 > 
    <  名称 > 草莓比利时华夫饼<  /name  > 
    <  价格 >  $ 7.95 <  /price  > 
    <  说明 > 比利时华夫饼覆盖着草莓和鲜奶油<  /description  > 
    <  卡路里 >  900 <  /卡路里 > 
  <  /food  
 
 </breakfast_menu  >  

解决方案

5.95 < /price < 描述 > 我们两个著名的比利时华夫饼，配以大量的真正的枫糖浆< /description > < 卡路里 > 650 < /卡路里 > < /food > < 食物 > < 名称 > 草莓比利时华夫饼< /name > < 价格 >

7.95 < /price > < 说明 > 比利时华夫饼覆盖着草莓和鲜奶油< /description > < 卡路里 > 900 < /卡路里 > < /food </breakfast_menu >

VB.NET中的XML文件解析 [ListView1.Columns.Add("Parameters", 100, HorizontalAlignment.Left) Dim xpathDocument As XPathDocument Dim xmlNavigator As XPathNavigator Dim xmlNodeIterator As XPathNodeIterator xpathDocument = New XPathDocument("C:\Users\Administrator\desktop\plant_catalog.xml") xmlNavigator = xpathDocument.CreateNavigator() xmlNodeIterator = xmlNavigator.Select("/admin/channel") xmlNavigator = xmlNodeIterator.Current xmlNodeIterator = xmlNavigator.SelectDescendants(XPathNodeType.Element, True) While xmlNodeIterator.MoveNext ListBox1.Items.Add(xmlNodeIterator.Current.Name) ListView1.Items.Add(xmlNodeIterator.Current.Name) End While

The below is my XML
Name, Price, Description and Calories these four have to come only once but they are repeating twice. any idea how to display only once

<xml version="1.0" encoding="ISO-8859-1" ?>
<breakfast_menu>
  <food>

    <calories>650</calories>
  </food>
  <food>
    <name>Strawberry Belgian Waffles</name>
    <price>$7.95</price>
    <description>light Belgian waffles covered with strawberries and whipped cream</description>
    <calories>900</calories>
  </food

</breakfast_menu>
