如何从 MS Word 中提取文本?

发布于 2024-11-24 07:29:12 字数 1851 浏览 0 评论 0原文

我正在尝试打开一个 Word 文档,然后提取文档中的所有文本并使用 Win32::OLE

#usr/bin/perl
#OLEWord.pl

#Use string and print warnings
use strict;use warnings;
#Using OLE + OLE constants for Variants and OLE enumeration for Enumerations
use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';

$Win32::OLE::Warn = 3;

#set the file to be opened
my $file = '/work/Test.docx';

#Create a new instance of Win32::OLE for the Word application, die if could not open the application
my $MSWord = Win32::OLE->new('Word.Application','Quit') and "Opened Word" or die     "Unable to open document ", Win32::OLE->LastError(); 
#Set the screen to Visible, so that you can see what is going on
$MSWord->{'Visible'} = 1;
#open the request file or die and print warning message
my $Doc = $MSWord->Documents->Open('C:\work\Test.docx') or die "Could not open ", $file, " Error:", Win32::OLE->LastError();

#$MSWord->ActiveDocument->SaveAs({Filename => 'AlteredTest.docx', 
                            #FileFormat => wdFormatDocument});
                            
                            
sub ShowObjs {
my $obj = shift;
foreach (sort keys %$obj) {
print "Keys: $_ - $obj->{$_}\n"; }
 }

 my $paragraphs = $Doc->Paragraphs;
 ShowObjs($paragraphs);

 #  Get and print the Text inside the opened file
 my $paragraphs = $Doc->Paragraphs;
 my $txt = $Doc->Range->Text;
 print $txt;
                            
 $MSWord->ActiveDocument->Close;
 $MSWord->Quit;

我收到以下错误代码:

来自“Microsoft Word”的 OLE 异常:

命令失败

Win32::OLE(0.1709) 错误 ox800a1066 在 OLEWord.pl 第 20 行的 METHOD/PROPERTYGET“Open”中

更新: 我可以正常打开 Word 应用程序,只是当我尝试打开文件时出现问题

I'm trying to open a word document and just extract all the text that is in the document and display it to the user using Win32::OLE

#usr/bin/perl
#OLEWord.pl

#Use string and print warnings
use strict;use warnings;
#Using OLE + OLE constants for Variants and OLE enumeration for Enumerations
use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';

$Win32::OLE::Warn = 3;

#set the file to be opened
my $file = '/work/Test.docx';

#Create a new instance of Win32::OLE for the Word application, die if could not open the application
my $MSWord = Win32::OLE->new('Word.Application','Quit') and "Opened Word" or die     "Unable to open document ", Win32::OLE->LastError(); 
#Set the screen to Visible, so that you can see what is going on
$MSWord->{'Visible'} = 1;
#open the request file or die and print warning message
my $Doc = $MSWord->Documents->Open('C:\work\Test.docx') or die "Could not open ", $file, " Error:", Win32::OLE->LastError();

#$MSWord->ActiveDocument->SaveAs({Filename => 'AlteredTest.docx', 
                            #FileFormat => wdFormatDocument});
                            
                            
sub ShowObjs {
my $obj = shift;
foreach (sort keys %$obj) {
print "Keys: $_ - $obj->{$_}\n"; }
 }

 my $paragraphs = $Doc->Paragraphs;
 ShowObjs($paragraphs);

 #  Get and print the Text inside the opened file
 my $paragraphs = $Doc->Paragraphs;
 my $txt = $Doc->Range->Text;
 print $txt;
                            
 $MSWord->ActiveDocument->Close;
 $MSWord->Quit;

I'm getting this error code:

OLE exception from "Microsoft Word":

Command Failed

Win32::OLE(0.1709) error ox800a1066
in METHOD/PROPERTYGET "Open" at OLEWord.pl line 20

Update: I can open up the Word application fine, it's just when I try to open up the file that is the problem

我有几个脚本可以使用 Win32::OLE 将 DOC 转换为各种输出格式。它们通常是这样开始的:

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';
my $wr = Win32::OLE->new('Word.Application')
    or die "Failure - word. \n";

$wr->{DisplayAlerts} = wdAlertsNone;
$wr->{Visible} = 0;

my $Doc = $wr->Documents->Open({
    FileName           => $input_file_path,
    ConfirmConversions => 0,
    AddToRecentFiles   => 0,
    Revert             => 0,
    ReadOnly           => 1,
    OpenAndRepair      => 0,
}) or exit;

...

请注意,$input_file_path 必须包含文件的绝对路径。您还可以启用 VisibleDisplayAlerts 以查看 Word 可能提供的任何错误。

编辑:您可以使用in枚举器遍历段落:

use Win32::OLE qw(in);

...

my $paragraphs = $Doc->Paragraphs;
for my $par (in $paragraphs) {
    print $par->Range->Text();
}

或者您可以使用Word自己的导出方法并将文档另存为支持的格式之一:

$Doc->SaveAs({
    FileName   => 'c:\\work\\Test.txt',
    FileFormat => wdFormatEncodedText,
});

后一种方法的优点是格式设置简单如果可能的话保留,这会为项目符号、编号等产生更好的结果。

I have few scripts to convert DOC to various output format using Win32::OLE. They usually start like this:

use Win32::OLE;
use Win32::OLE::Const 'Microsoft Word';
my $wr = Win32::OLE->new('Word.Application')
    or die "Failure - word. \n";

$wr->{DisplayAlerts} = wdAlertsNone;
$wr->{Visible} = 0;

my $Doc = $wr->Documents->Open({
    FileName           => $input_file_path,
    ConfirmConversions => 0,
    AddToRecentFiles   => 0,
    Revert             => 0,
    ReadOnly           => 1,
    OpenAndRepair      => 0,
}) or exit;

...

Please note that $input_file_path has to contain absolute path to your file. You can also enable Visible and DisplayAlerts to see any error Word might give you.

Edit: You can traverse paragraphs using in enumerator:

use Win32::OLE qw(in);

...

my $paragraphs = $Doc->Paragraphs;
for my $par (in $paragraphs) {
    print $par->Range->Text();
}

Or you can use Word's own exporting method and save document as one of supported formats:

$Doc->SaveAs({
    FileName   => 'c:\\work\\Test.txt',
    FileFormat => wdFormatEncodedText,
});

The advantage of latter method is that formatting is retained if possible, which produces better results for bullets, numbering and such.

Win32::OLE 交互方面可能有点有趣。如果有任何事情触发提示,您可能会收到这样的消息。例如,通常它可能想要以只读方式打开文件,并打开一个对话框,但这些对话框可能会在 Win32::OLE 的默认初始化下中断。

如果是这种情况,

Win32::OLE->Initialize(Win32::OLE::COINIT_OLEINITIALIZE);

在实例化任何对象之前调用(即在 Win32::OLE->new 之前)可能会成功。

Win32::OLE can be a little funny about interaction. if anything triggers a prompt, you may get a message like this. Typically it may be that it wants to open the file read-only, for example, and put up a dialog, but these dialogs can break under the default initialization of Win32::OLE.

If this is the case, calling

Win32::OLE->Initialize(Win32::OLE::COINIT_OLEINITIALIZE);

before you do anything like instantiate any objects (i.e., before Win32::OLE->new) might do the trick.
