Xml を受け取り、それをプレーン テキストに変換するものを C# で書きたいと思います。

このようなことはすでにありますか？どうすればこれを行うことができますか？

これは、まだ多くの作業が必要なアイデアです。

private void dataGridViewResult_SelectionChanged(object sender, EventArgs e)
        {
            if (this.dataGridViewResult.SelectedRows.Count > 0)
            {
                XslCompiledTransform xslt = new XslCompiledTransform();
                xslt.Load("SQL"); //.xml

                xslt.Transform("SQL","SQL"); //.xml, .html
                this.richTextBoxSQL.Text = this.dataGridViewResult.SelectedRows[0].Cells["SQL"].Value.ToString();
            }
        }

次の XSLT スクリプトは、必要なことを行います。

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text"/>
    <xsl:template match="*">
        <xsl:for-each select="*">
            <xsl:value-of select="local-name()"/>
            <xsl:text> </xsl:text>
            <xsl:value-of  select="."/>
            <xsl:text>
</xsl:text>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

XslCompiledTransform次に、クラスをそのまま使用してスクリプトを適用できます。

private string transformXml(string sourceXmlText, string xsltText)
{
    XmlDocument sourceXmlDocument = new XmlDocument();
    sourceXmlDocument.LoadXml(sourceXmlText);
    XslCompiledTransform transformer = new XslCompiledTransform();
    XmlTextReader xsltReader = new XmlTextReader(new StringReader(xsltText));
    transformer.Load(xsltReader);
    MemoryStream outputStream = new MemoryStream();
    XmlWriter xmlWriter = XmlWriter.Create(outputStream, transformer.OutputSettings);
    transformer.Transform(sourceXmlDocument, null, xmlWriter);
    outputStream.Position = 0;
    StreamReader streamReader = new StreamReader(outputStream);
    return streamReader.ReadToEnd();
}

投稿されている他のソリューションよりも明らかに複雑ですが、フォーマットを変更する必要がある場合にスクリプトを簡単に変更できるという大きな利点があります。

このようなもの：

    XmlDocument doc = new XmlDocument();
    doc.LoadXml(your text string);

    StringBuilder sb = new StringBuilder();
    foreach (XmlNode node in doc.DocumentElement.ChildNodes)
    {
        sb.Append(char.ToUpper(node.Name[0]));
        sb.Append(node.Name.Substring(1));
        sb.Append(' ');
        sb.AppendLine(node.InnerText);
    }

    Console.WriteLine(sb);

あなたは次のようなことをすることができます

    string xml = @"<note>
                    <to>Tove</to>
                    <from>Jani</from>
                    <heading>Reminder</heading>
                    <body>Don't forget me this weekend!</body>
                </note>";

    StringBuilder sb = new StringBuilder();
    foreach (XElement element in XDocument.Parse(XML-STRING).Descendants("note"))
    {
        sb.AppendLine(string.Format("{0} {1}", element.Name, element.Value));
    }

ここでの回答は、属性のない単純な XML ファイルに対して完全に機能します。ノードに属性と値の両方を含む可能性のある XML を処理するには、もっと複雑なものが必要です。「リスト項目」は言うまでもありません (同じノード名で属性が異なる項目。例: <Books><Book ID="10" Author="Me" /><Book ID="20" Author) ="you"/></Books>)。XML ファイルを TAB 区切りのテキストに変換する必要があり、すべてのケースを含める必要がありました。このコードは、数千のノードを持ついくつかの xml ファイルでテストされ、動作しています。「リスト項目」は、「|」を使用して、「リスト」の各属性または要素の値を既存の列に追加することによって処理されます。セパレーターとして。似たようなことをしたいと思っていて、出発点が必要な人に役立つことを願っています。誰かがこれを読んでいて、それを行うためのより良い方法を知っているなら、私は本当にそれについて聞きたいです.
