如何保持打开的 xml 文档的样式

我使用开放 XML（Microsoft Word - .docx）作为文件模板来自动生成其他文档。在模板文档中，我定义了内容控件，并编写了代码来替换这些内容控件中的内容。

内容被替换并生成文档，但我正在努力保持风格。在Word中，在检查内容控件的属性时，我选中了“使用样式将文本格式化为空控件：样式”复选框，并选中了“编辑内容时删除内容控件”。当文档由代码生成时，这似乎没有任何影响。

This is my code (which a community member here was kind enough to help with) for replacing the data in the content controls. Any ideas what I should do in order to keep the formatting? The formatting is simple text formatting, like size and font. Please advice:

    private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
    {
        //grab all the tag fields
        var tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
            (r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);

        foreach (var field in tagFields)
        {
            //remove all paragraphs from the content block
            field.SdtContentBlock.RemoveAllChildren<DocumentFormat.OpenXml.Wordprocessing.Paragraph>();
            //create a new paragraph containing a run and a text element
            var newParagraph = new DocumentFormat.OpenXml.Wordprocessing.Paragraph();
            var newRun = new DocumentFormat.OpenXml.Wordprocessing.Run();
            var newText = new DocumentFormat.OpenXml.Wordprocessing.Text(tagValue);
            newRun.Append(newText);
            newParagraph.Append(newRun);
            //add the new paragraph to the content block
            field.SdtContentBlock.Append(newParagraph);
        }
    }

当您为内容控件分配新的样式时RunProperties元素被添加到下面SdtProperties。例如，如果我分配一个名为的新样式Style1我可以看到生成了以下 XML：

<w:sdt>
    <w:sdtPr>
        <w:rPr>
            <w:rStyle w:val="Style1" />
        </w:rPr>
    <w:alias w:val="LastName" />
    <w:tag w:val="LastName" />
    ....

您需要获取该值并将其分配给新的Paragraph您正在创建，添加Paragraph与SdtBlock然后删除SdtBlock这就是当您选择“编辑内容时删除内容控件”选项时 Word 所做的操作。这RunProperties是<w:rPr>元素。以下内容应该可以完成您的任务。

private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
{
    //grab all the tag fields
    IEnumerable<SdtBlock> tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
        (r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);

    foreach (var field in tagFields)
    {
        //grab the RunProperties from the SdtBlcok
        RunProperties runProp = field.SdtProperties.GetFirstChild<RunProperties>();

        //create a new paragraph containing a run and a text element
        Paragraph newParagraph = new Paragraph();
        Run newRun = new Run();
        if (runProp != null)
        {
            //assign the RunProperties to our new run
            newRun.Append(runProp.CloneNode(true));
        }
        Text newText = new Text(tagValue);
        newRun.Append(newText);
        newParagraph.Append(newRun);
        //insert the new paragraph before the field we're going to remove
        field.Parent.InsertBefore(newParagraph, field);

        //remove the SdtBlock to mimic the Remove content control when contents are edited option
        field.Remove();
    }
}
