xml - 只想为父节点编写带有属性的 XML 注释。

Question

我想编写带有父节点属性的 XML 文件...（在 VB.NET 中）我知道如何编写 XML 节点，但我还没有编写带有属性的 XML 节点...如何编写？我已经写了下面的代码，但坚持如何用属性编写节点......

        xmlWriter__1 = XmlWriter.Create("C:\Data\Trial1.xml)

        xmlWriter__1.WriteStartDocument()

        xmlWriter__1.WriteStartElement("Data")

        xmlWriter__1.WriteStartElement("Trial")



        xmlWriter__1.WriteStartElement("FlatAllocation")
        'Flat Name String 

        xmlWriter__1.WriteStartElement("FlatName")

        xmlWriter__1.WriteString(Convert.ToString(FlatString))

        xmlWriter__1.WriteEndElement()

        'ID
        xmlWriter__1.WriteStartElement("CatID")

        xmlWriter__1.WriteString(Convert.ToString(catId))

        xmlWriter__1.WriteEndElement()

        xmlWriter__1.WriteEndDocument()

        xmlWriter__1.Close()

我想在 XML 文件下面写：

<?xml version="1.0" encoding="utf-8"?>
<Data>
<Trial No="1">
  <FlatAllocation>
    <FlatName>115</FlatName>
    <CatID>1</CatID>
  </FlatAllocation>
</Trial>
<Trial No="2">
  <FlatAllocation>
    <FlatName>A/1###108</FlatName>
    <CatID>1</CatID>
  </FlatAllocation>
  <FlatAllocation>
    <FlatName>A/2###10688</FlatName>
    <CatID>1</CatID>
  </FlatAllocation>
</Trial>
</Data>

尝试这个，

xmlWriter__1 = XmlWriter.Create("C:\Data\Trial1.xml)
xmlWriter__1.WriteStartDocument()
xmlWriter__1.WriteStartElement("Data")
xmlWriter__1.WriteStartElement("Trial")

'add this after the Trial element
xmlWriter__1.WriteAttributeString("No", "1");

xmlWriter__1.WriteStartElement("FlatAllocation")
'Flat Name String 
xmlWriter__1.WriteStartElement("FlatName")
xmlWriter__1.WriteString(Convert.ToString(FlatString))
xmlWriter__1.WriteEndElement()
'ID
xmlWriter__1.WriteStartElement("CatID")
xmlWriter__1.WriteString(Convert.ToString(catId))
xmlWriter__1.WriteEndElement()
xmlWriter__1.WriteEndDocument()
xmlWriter__1.Close()
