vba 如何解析 XML 文件并写入数据然后保存

How to parse an XML file and write in data then save it

提问by user3232996

I am working on something like the following:

我正在研究以下内容：

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).

1. 包含一些单元格的 Excel 工作表，要求最终用户输入所需的值；完毕
2. 读取最终用户在这些单元格中输入的值的代码；
3. 加载一个 XML 文件；完毕
4. 解析它，然后将从 Excel 单元格中检索到的值写入 XML 文件（遵循规则）然后保存；我被困在这里了！
5. 启动我的应用程序（另一个脚本稍后将使用 XML 文件值）。

I will simplify as much as possible:

我会尽量简化：

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

Excel 文件将类似于以下示例...

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

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

“T”指的是标题。最终用户将输入值 V1、V2、... V6

The XML file is structured like this:

XML 文件的结构如下：

<?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>

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

如您所见，我需要解析此文件并为每个文件输入参考值 (V1....V6)。

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

Here is some code that can help you get started

这是一些可以帮助您入门的代码

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

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.
