Question

我在python中使用pyuno从大量excel文件中提取数据。

我的问题是，我打开每个文件并用

关闭一个窗口

url = unohelper.systemPathToFileUrl(os.path.abspath(file_name))
file = desktop.loadComponentFromURL(url, "_blank", 0, () )

和

file.close(True)

有没有办法从文件中提取数据而根本不打开窗口？或者至少没有为每个文件打开一个新窗口？

这会打开一个文档而不显示：

// Call the bootstrap to get the Component context
com.sun.star.uno.XComponentContext oComponentContext = null;
try
{
    String oooExeFolder = "C:/Program Files/OpenOffice.org 3/program/";
    oComponentContext = BootstrapSocketConnector.bootstrap(oooExeFolder);
}
catch(com.sun.star.comp.helper.BootstrapException ex)
{
    System.out.println(ex.getMessage());
}

if(oComponentContext != null)
{

    com.sun.star.lang.XComponent oComponent;
    com.sun.star.sheet.XSpreadsheetDocument oSpreadDocument;
    com.sun.star.frame.XComponentLoader oComponentLoader;
    try
    {

            // Get the service manager
        com.sun.star.lang.XMultiComponentFactory oMultiComponentFactory =
                oComponentContext.getServiceManager();
            // Create a new desktop instance

            oComponentLoader  =

            /// Read the created file

            property[0] = new com.sun.star.beans.PropertyValue();

            oComponent =
                oComponentLoader.loadComponentFromURL(
                        "file:///c:/test/sheetdoc.ods",
                        // "private:factory/swriter", //Blank document

                        0,                      // no search flags
                        // read only
                        property);
            // Get the spread sheet
            oSpreadDocument =
                (com.sun.star.sheet.XSpreadsheetDocument)
                com.sun.star.uno.UnoRuntime.queryInterface(
                        com.sun.star.sheet.XSpreadsheetDocument.class, oComponent);
    }
catch(Exception  ex)
{
    System.out.println("An exception occurs at opening of document: "+ex.getMessage());
    return;
}

 } // end of if
 System.exit(0);

在UNO的同一窗口中打开多个文档
