如何解析XML文件并写入数据，然后保存 [英] How to parse an XML file and write in data then save it

问题描述

我正在处理如下事情：

1. 带有一些单元格的Excel表格，最终用户被要求输入
   所需值;完成


2. 最终用户读取这些单元格
   中输入的值的代码;


3. 加载XML文件;完成


4. 解析它，然后将从Excel单元格检索的值写入XML文件（遵循规则），然后保存;我被困在这里


5. 启动我的应用程序（另一个脚本会在以后使用XML文件值）。

1. An Excel sheet with some cells where the end user is asked to enter required values; done
2. Code that read values entered in these cells by end users;
3. Load an XML file; done
4. Parse it and then write the values retrieved from Excel cells into XML file (following a rule) then save it; I am stuck here!
5. Start my application (another script will use the XML file values later).

将尽可能简化：

Excel文件将如以下示例...

The Excel file will be like the following example...

   CellA     CellB
1  T1        V1
2  T2        V2
3  T3        V3
4  T4        V4
5  T5        V5
6  T6        V6

T表示标题。最终用户将输入值V1，V2，... V6

"T" refers to title. The end user will enter the Values V1, V2, ... V6

XML文件的结构如下：

The XML file is structured like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Environment>
    <Variable>
        <Name></Name>
        <Caption>T1</Caption>
        <Type>TEXT</Type>
        <Value>V1</Value>
        <Description></Description>
    </Variable>
        <Variable>
        <Name></Name>
        <Caption>T2</Caption>
        <Type>TEXT</Type>
        <Value>V2</Value>
        <Description></Description>
    </Variable>
        <Variable>
        <Name></Name>
        <Caption>T3</Caption>
        <Type>TEXT</Type>
        <Value>V3</Value>
        <Description></Description>
    </Variable> <Variable>
        <Name></Name>
        <Caption>T4</Caption>
        <Type>TEXT</Type>
        <Value>V4</Value>
        <Description></Description>
    </Variable> <Variable>
        <Name></Name>
        <Caption>T5</Caption>
        <Type>TEXT</Type>
        <Value>V5</Value>
        <Description></Description>
    </Variable>
    </Variable> <Variable>
        <Name></Name>
        <Caption>T6</Caption>
        <Type>TEXT</Type>
        <Value>V6</Value>
        <Description></Description>
    </Variable>
</Environment>

如您所见，我需要解析此文件并输入值（V1 .... V6）参考每一个。

As you can see I need to parse this file and enter values (V1....V6) into with reference to for each one.

以下是我的VBA代码，直到我被卡住的行：

Below is my VBA code until the line where I am stuck:

'Option Explicit
Private Sub RunTest_Click()

Dim envFrmwrkPath As String
Dim ApplicationName As String
Dim TestIterationName, ServerIp, Login, Password, TraderLiteLogPath  As String
Dim objfso, app, Eval As Object
Dim i, Msgarea`enter code here`

Dim EnvVarXML As MSXML2.DOMDocument60

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'''these are added when trying to find a way to parse the xml --- you can change them
Dim Variable As MSXML2.IXMLDOMNode
'Dim oAttributes As MSXML.IXMLDOMNamedNodeMap
Dim ORoot As MSXML2.IXMLDOMNode
Dim objUIElement As MSXML2.IXMLDOMElement

'load Env Variables from Excel

ApplicationName = ActiveSheet.Range("E4").Value

'load xml file
Set objParser = CreateObject("Microsoft.XMLDOM")
Set EnvVarXML = New MSXML2.DOMDocument60


'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
''test_load
'''''''''''''''-----------------------------------------------------
'Set EnvVarXML = CreateObject("Microsoft.XMLDOM")
'Set EnvVarXML = New MSXML2.DOMDocument60
 'If EnvVarXML.Load(envFrmwrkPath & "\Environment\EnvVar.xml") Then
  ' for debug only
  'MsgBox "file loaded correctly", vbOKOnly

 'MsgBox "file not loaded", vbcrtical
 ' for debug only
  'End If
'''''''''''''''-----------------------------------------------------
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

'load xml file
EnvVarXML.Load (envFrmwrkPath & "\Environment\EnvVar.xml")

 'parse file and change values
 '''the following may have no sense for an experiment one of you
 Set ORoot = EnvVarXML.DocumentElement
 For Each OVariable In ORoot.ChildNodes
   Set OAttributes = OVariable.Attributes
   Set OChildren = OVariable.ChildNodes
    '''deleted many lines as found no way ''''''' 
       Set EnvVarXML = Nothing
 Next
    EnvVarXML.Save (envFrmwrkPath & "\Environment\EnvVar.xml")

推荐答案

这是一些可以帮助您开始的代码

Here is some code that can help you get started

Dim doc As DOMDocument
Set doc = New DOMDocument
doc.Load "C:\x.xml"
Dim Variables As IXMLDOMNodeList
Dim variable As IXMLDOMNode
Set Variables = doc.SelectNodes("/Environment/Variable")
For Each variable In Variables
    Debug.Print variable.SelectNodes("Caption").Item(0).Text
    Debug.Print variable.SelectNodes("Type").Item(0).Text
Next

要使其正常工作，请选择工具 - 引用，然后选择Microsoft XML v6.0。
有很多方法可以解决这个问题，但XPath（SelectNodes中使用的语言）在这种情况下是非常好的。

To make it work, select Tools - References and select Microsoft XML v6.0. There are many ways to solve this, but XPath (the language used in SelectNodes) is very good to know in cases like this.
