能否提供word中的结构化数据？

[sangeren]

比较有一个word试卷有10道试题，每道试题有问题和答案，能否解析出10道试题的结构化数据，包含每一个试题的问题和答案。谢谢

@sangeren 您可以分析文档结构。请参阅我们的文档以了解有关 Aspose.Words 文档对象模型的更多信息：

PS：获得支持的主要地方是 Aspose.Words 支持论坛：

想结构化数据输出json, 保留word大纲级别， 段落内容， 表格， 图片； 无需保留样式， 我尝试从word2html, 再从html2json； 输出结果只有文本， 没有大纲，表格，图片等, 使用代码如下：

Document doc = new Document("input.docx");
doc.Save("output.html", Aspose.Words.SaveFormat.Html);
var workbook = new Workbook("output.html");
workbook.Save("output.json", Aspose.Cells.SaveFormat.Json);

@verydemo 没有内置方法可以将文档转换为 JSON。但是，您可以通过检查文档对象模型来实现这一点。以下是将文档转换为 JSON 的简化代码：
https://docs.aspose.com/words/java/aspose-words-document-object-model/

private static string GetJson(Document doc)
{
    StringBuilder sb = new StringBuilder();
    int indent = 1;
    sb.Append(OpenJson());
    sb.Append(OpenElement(doc, indent++));
    foreach (Section section in doc.Sections)
    {
        sb.Append(OpenElement(section, indent++));
        HandleContainer(sb, section.Body, ref indent);
        sb.Append(CloseElement(--indent, (section.NextSibling == null)));
    }
    sb.Append(CloseElement(--indent, true));
    sb.Append(CloseElement(0, true));
    return sb.ToString();
}

private static void HandleContainer(StringBuilder sb, CompositeNode container, ref int indent)
{
    if (!container.HasChildNodes)
        sb.Append(OpenAndCloseElement(container, indent, (container.NextSibling == null)));
    else
    {
        sb.Append(OpenElement(container, indent++));
        foreach (Node node in container.ChildNodes)
        {
            CompositeNode childContainer = node as CompositeNode;
            if (childContainer != null)
                HandleContainer(sb, childContainer, ref indent);
            else
                HandleNode(sb, node, ref indent);
        }
        sb.Append(CloseElement(--indent, (container.NextSibling == null)));
    }
}

private static void HandleNode(StringBuilder sb, Node node, ref int indent)
{
    switch (node.NodeType)
    {
        case NodeType.Run:
            sb.Append(OpenElement(node, indent++));
            Run run = node as Run;
            // for shorter output 
            {
                //sb.Append(WriteElement(nameof(run.Text), run.Text, indent, false));
                //HandleFont(sb, run.Font, ref indent, true);
                sb.Append(WriteElement(nameof(run.Text), run.Text, indent, true));
            }
            sb.Append(CloseElement(--indent, (node.NextSibling == null)));
            break;
        default:
            break;
    }
}

private static void HandleFont(StringBuilder sb, Font font, ref int indent, bool isLast)
{
    sb.Append(OpenElement("Font", indent++));
    sb.Append(WriteElement(nameof(font.Name), font.Name, indent, false));
    sb.Append(WriteElement(nameof(font.Size), font.Size, indent, true));
    sb.Append(CloseElement(--indent, isLast));
}

private static string OpenJson() { return "{\n"; }
private static string OpenElement(Node node, int indent) { return OpenElement(GetNodeName(node), indent); }
private static string OpenElement(string name, int indent) { return GetIndent(indent) + GetQuoted(name) + " : {\n"; }
private static string OpenAndCloseElement(Node node, int indent, bool isLast)
{
    return GetIndent(indent) + GetQuoted(GetNodeName(node)) + " : { }" + GetComma(isLast) + "\n";
}
private static string WriteElement(string name, string value, int indent, bool isLast)
{
    return GetIndent(indent) + GetQuoted(name) + " : " + GetQuoted(value) + GetComma(isLast) + "\n";
}
private static string WriteElement(string name, double value, int indent, bool isLast)
{
    return GetIndent(indent) + GetQuoted(name) + " : " + value + GetComma(isLast) + "\n";
}
private static string CloseElement(int indent, bool isLast) { return GetIndent(indent) + "}" + GetComma(isLast) + "\n"; }
private static string GetNodeName(Node node) { return node.NodeType.ToString(); }
private static string GetQuoted(string value) { return "\"" + value + "\""; }
private static string GetComma(bool isLastElement) { return isLastElement ? string.Empty : ","; }
private static string GetIndent(int indent) { return new string(' ', indent * 2); }

或者，您可以使用 DocumentVisitor 将文档结构写入您自己的自定义格式。
