如何在 .NET 中创建 OpenOffice 文档

Question

我开始编写一个输出 OpenOffice 文档的应用程序。空 ODT 文档中的 content.xml 文件开头为：

<?xml version="1.0" encoding="UTF-8"?>
<office:document-content
    xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"
    xmlns:style="urn:oasis:names:tc:opendocument:xmlns:style:1.0"
    xmlns:text="urn:oasis:names:tc:opendocument:xmlns:text:1.0"
    xmlns:table="urn:oasis:names:tc:opendocument:xmlns:table:1.0"
    xmlns:draw="urn:oasis:names:tc:opendocument:xmlns:drawing:1.0"
    xmlns:fo="urn:oasis:names:tc:opendocument:xmlns:xsl-fo-compatible:1.0"
    xmlns:xlink="http://www.w3.org/1999/xlink"
    xmlns:dc="http://purl.org/dc/elements/1.1/"
    xmlns:meta="urn:oasis:names:tc:opendocument:xmlns:meta:1.0"
    xmlns:number="urn:oasis:names:tc:opendocument:xmlns:datastyle:1.0"
    xmlns:svg="urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0"
    xmlns:chart="urn:oasis:names:tc:opendocument:xmlns:chart:1.0"
    xmlns:dr3d="urn:oasis:names:tc:opendocument:xmlns:dr3d:1.0"
    xmlns:math="http://www.w3.org/1998/Math/MathML"
    xmlns:form="urn:oasis:names:tc:opendocument:xmlns:form:1.0"
    xmlns:script="urn:oasis:names:tc:opendocument:xmlns:script:1.0"
    xmlns:ooo="http://openoffice.org/2004/office"
    xmlns:ooow="http://openoffice.org/2004/writer"
    xmlns:oooc="http://openoffice.org/2004/calc"
    xmlns:dom="http://www.w3.org/2001/xml-events"
    xmlns:xforms="http://www.w3.org/2002/xforms"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:rpt="http://openoffice.org/2005/report"
    xmlns:of="urn:oasis:names:tc:opendocument:xmlns:of:1.2"
    xmlns:rdfa="http://docs.oasis-open.org/opendocument/meta/rdfa#"
    xmlns:
        field="urn:openoffice:names:experimental:ooo-ms-interop:xmlns:field:1.0"
    office:version="1.2">

我以前没有在 XML 中见过冒号。我知道它们表示名称空间。我该如何在 .NET 中重新创建它？

Answer 1

OpenOffice 包含用于处理 OpenOffice 文档的 .NET 程序集。您应该使用它们而不是直接使用 XML。这会更容易并且更不容易出错。

Answer 2

以下代码会将所有正确的命名空间加载到命名空间管理器中并创建示例文档。 .NET 将仅输出文档中实际使用的命名空间，而不是全部。我不确定是否有办法强制输出未使用的，但确实不需要未使用的。

public static void Test()
{
    var nt = new NameTable();
    var ns = new XmlNamespaceManager(nt);
    var doc = new XmlDocument(nt);

    ns.AddNamespace("office", "urn:oasis:names:tc:opendocument:xmlns:office:1.0");
    ns.AddNamespace("style", "urn:oasis:names:tc:opendocument:xmlns:style:1.0");
    ns.AddNamespace("text", "urn:oasis:names:tc:opendocument:xmlns:text:1.0");
    ns.AddNamespace("table", "urn:oasis:names:tc:opendocument:xmlns:table:1.0");
    ns.AddNamespace("draw", "urn:oasis:names:tc:opendocument:xmlns:drawing:1.0");
    ns.AddNamespace("fo", "urn:oasis:names:tc:opendocument:xmlns:xsl-fo-compatible:1.0");
    ns.AddNamespace("xlink", "http://www.w3.org/1999/xlink");
    ns.AddNamespace("dc", "http://purl.org/dc/elements/1.1/");
    ns.AddNamespace("meta", "urn:oasis:names:tc:opendocument:xmlns:meta:1.0");
    ns.AddNamespace("number", "urn:oasis:names:tc:opendocument:xmlns:datastyle:1.0");
    ns.AddNamespace("svg", "urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0");
    ns.AddNamespace("chart", "urn:oasis:names:tc:opendocument:xmlns:chart:1.0");
    ns.AddNamespace("dr3d", "urn:oasis:names:tc:opendocument:xmlns:dr3d:1.0");
    ns.AddNamespace("math", "http://www.w3.org/1998/Math/MathML");
    ns.AddNamespace("form", "urn:oasis:names:tc:opendocument:xmlns:form:1.0");
    ns.AddNamespace("script", "urn:oasis:names:tc:opendocument:xmlns:script:1.0");
    ns.AddNamespace("ooo", "http://openoffice.org/2004/office");
    ns.AddNamespace("ooow", "http://openoffice.org/2004/writer");
    ns.AddNamespace("oooc", "http://openoffice.org/2004/calc");
    ns.AddNamespace("dom", "http://www.w3.org/2001/xml-events");
    ns.AddNamespace("xforms", "http://www.w3.org/2002/xforms");
    ns.AddNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
    ns.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
    ns.AddNamespace("rpt", "http://openoffice.org/2005/report");
    ns.AddNamespace("of", "urn:oasis:names:tc:opendocument:xmlns:of:1.2");
    ns.AddNamespace("rdfa", "http://docs.oasis-open.org/opendocument/meta/rdfa#");
    ns.AddNamespace("field", "urn:openoffice:names:experimental:ooo-ms-interop:xmlns:field:1.0");

    var root = doc.CreateElement("office", "document-content");
    var attr = doc.CreateAttribute("office", "version", ns.LookupNamespace("office"));
    attr.Value = "1.2";
    root.Attributes.Append(attr);
    doc.AppendChild(root);

    using (var xw = new XmlTextWriter(Console.Out))
    {
        xw.Formatting = Formatting.Indented;
        xw.Indentation = 2;
        xw.IndentChar = ' ';

        doc.WriteTo(xw);
    }
}
