Question

我试图在XML文档中获取最后一段文件名。目前，一些用户正在发送完整的文件路径，但不是全部。我知道在处理物理文件时如何进行修剪，但是当路径包含在“ecf：DocumentRendition”元素下的XML的“nc：DocumentFileControlID”元素中时，我知道。我想要在最后一个“\”之后和.pdf或.doc文件扩展名之前的路径。

C＃代码：

private void btnGet_File_Click(object sender, System.EventArgs e)
{
    OpenFileDialog1.Title = "Please Select a File";
    OpenFileDialog1.InitialDirectory = @"filepath";
    OpenFileDialog1.FileName = TextBox1.Text;
    OpenFileDialog1.Filter = TextBox1.Text + "|*.xml";

    OpenFileDialog1.ShowDialog();
    string b64str = null;
    byte[] binaryData = null;
    System.IO.FileStream fs = null;
    XmlReader xr = XmlReader.Create(fileToOpen);

    ListBox1.Items.Clear();

    while (xr.Read())
    {
        if (xr.NodeType == XmlNodeType.Element && xr.Name == "nc:DocumentFileControlID")
        {
            fileToSave = xr.ReadElementString();
            if (fileToSave.Contains(".pdf") || fileToSave.Contains(".doc"))
            {
                ListBox1.Items.Add(fileToSave);
            }
        }
        if (xr.NodeType == XmlNodeType.Element && xr.Name == "nc:BinaryBase64Object")
        {
            b64str = xr.ReadElementString();
            binaryData = Convert.FromBase64String(b64str);

            fileToSave = "C:\\xml_images\\" + fileToSave;
            fs = new FileStream(fileToSave, FileMode.Create);

            // write it out
            fs.Write(binaryData, 0, binaryData.Length);

            // close it down.
            fs.Close();
            binaryData = null;
            fileToSave = null;
        }
    }
    MessageBox.Show("All files are saved in C:\\xml_images");
}

Answer 1

使用

System.IO.Path.GetFileNameWithoutExtension("H:\BCA E-Filing Folder\EFRAIN\13-256382_FC01_SUMMONS_BREVARD1.pdf");

那将得到

13-256382_FC01_SUMMONS_BREVARD1

您需要首先从元素节点的值中提取数据。我已经使用你的xml并使用Linq解析它到Xml并提取了值。请注意，有许多DocumentFileControlID，我只是寻找一个具有c：或h：type模式进行区分的模式。您的处理方式会有所不同。

    XNamespace nc = "http://niem.gov/niem/niem-core/2.0";

    var node =
    XElement.Parse(GetXMlData())
            .Descendants(nc + "DocumentFileControlID")
            .Where (element => Regex.IsMatch(element.Value, @"(^[A-Z]\:)"))
        //  .Select (element => Path.GetFileName(element.Value)) // Use this to just get the filename.
            .FirstOrDefault();

    Console.WriteLine (node); // <nc:DocumentFileControlID xmlns:nc="http://niem.gov/niem/niem-core/2.0">H:\`BCA E-Filing Folder\EFRAIN\13-256382_FC01_SUMMONS_BREVARD1.pdf</nc:DocumentFileControlID>

    Console.WriteLine (Path.GetFileName(node.Value));   
//  13-256382_FC01_SUMMONS_BREVARD1.pdf

GetData看起来像这样：

使用Path.GetFileName来确定文件是否有路径，只返回文件名。

Path.GetFileName(@"H:\`BCA E-Filing Folder\EFRAIN\13-256382_FC01_SUMMONS_BREVARD1.pdf")

    /* returns
     13-256382_FC01_SUMMONS_BREVARD1.pdf
    */
