我试图在从我们的系统发送之前从 word 文件中删除敏感信息。下面是要发送的文件中的自定义属性示例。我想删除 filePath 和 templateFilePath 的内容。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes">
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="2" name="docId">
        <vt:lpwstr>123</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="3" name="verId">
        <vt:lpwstr>1</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="4" name="templateId">
        <vt:lpwstr>321</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="5" name="fileId">
        <vt:lpwstr>123</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="6" name="filePath">
        <vt:lpwstr>I want to remove this</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="7" name="templateFilePath">
        <vt:lpwstr>I want to remove this</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="8" name="filePathOneNote">
        <vt:lpwstr>\</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="9" name="fileName">
        <vt:lpwstr>test.docx</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="10" name="comment">
        <vt:lpwstr>Test comment</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="11" name="sourceId">
        <vt:lpwstr>12345</vt:lpwstr>
    </property>
    <property fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" pid="12" name="module">
        <vt:lpwstr>Document</vt:lpwstr>
    </property>
</Properties>

我从 Open XML SDK 生产力工具获得了这段代码:

private static void ChangeCustomFilePropertiesPart(CustomFilePropertiesPart customFilePropertiesPart)
{
    CustomProperties.Properties properties = customFilePropertiesPart.Properties;

    CustomProperties.CustomDocumentProperty customDocumentProperty1 = properties.Elements<CustomProperties.CustomDocumentProperty>().ElementAt(4);
    CustomProperties.CustomDocumentProperty customDocumentProperty2 = properties.Elements<CustomProperties.CustomDocumentProperty>().ElementAt(5);

    VariantTypes.VTLPWSTR vTLPWSTR1 = customDocumentProperty1.GetFirstChild<VariantTypes.VTLPWSTR>();
    vTLPWSTR1.Text = "";


    VariantTypes.VTLPWSTR vTLPWSTR2 = customDocumentProperty2.GetFirstChild<VariantTypes.VTLPWSTR>();
    vTLPWSTR2.Text = "";

}

但是我不能相信我要删除的属性是数字 4 和 5,所以我必须在删除文本之前通过 name 属性找到它们。谁能帮我?我想以某种方式使用 linq 或 Open XML SDK。

谢谢!

您不要通过 查询@pid,因为这可能会改变。改为查询,@name对于自定义文档属性,它将始终保持相同的值;因此,在您的情况下,只需使用 Lambda 查询 Where @name = "templateFilePath" ,然后将其设置为空,然后将其.Value复制回来并保存。

这是我想出的代码:

private void ChangeCustomFilePropertiesPart(CustomFilePropertiesPart customFilePropertiesPart)
{
    var props = from n in customFilePropertiesPart.Properties.Elements<CustomProperties.CustomDocumentProperty>()
                where n.Name == "filePath" || n.Name == "templateFilePath"
                select n;

    foreach (var prop in props)
    {
        VariantTypes.VTLPWSTR value = prop.GetFirstChild<VariantTypes.VTLPWSTR>();
        value.Text = "";
    }
}
