Extract text from doc and docx

问题

I would like to know how can I read the contents of a doc or docx. I\'m using a Linux VPS and PHP, but if there is a simpler solution using other language, please let me know, as long as it works under a linux webserver.

回答1:

This is a .DOCX solution only. For .DOC or .PDF you'll need to use something else like pdf2text.php for PDF

function docx2text($filename) {
   return readZippedXML($filename, "word/document.xml");
 }

function readZippedXML($archiveFile, $dataFile) {
// Create new ZIP archive
$zip = new ZipArchive;

// Open received archive file
if (true === $zip->open($archiveFile)) {
    // If done, search for the data file in the archive
    if (($index = $zip->locateName($dataFile)) !== false) {
        // If found, read it to the string
        $data = $zip->getFromIndex($index);
        // Close archive file
        $zip->close();
        // Load XML from a string
        // Skip errors and warnings
        $xml = new DOMDocument();
    $xml->loadXML($data, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING);
        // Return data without XML formatting tags
        return strip_tags($xml->saveXML());
    }
    $zip->close();
}

// In case of failure return empty string
return "";
}

echo docx2text("test.docx"); // Save this contents to file

Here i have added the solution to get the text from .doc,.docx word files

How to extract text from word file .doc,docx php

For .doc

private function read_doc() {
    $fileHandle = fopen($this->filename, "r");
    $line = @fread($fileHandle, filesize($this->filename));   
    $lines = explode(chr(0x0D),$line);
    $outtext = "";
    foreach($lines as $thisline)
      {
        $pos = strpos($thisline, chr(0x00));
        if (($pos !== FALSE)||(strlen($thisline)==0))
          {
          } else {
            $outtext .= $thisline." ";
          }
      }
     $outtext = preg_replace("/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/","",$outtext);
    return $outtext;
}

For .docx

private function read_docx(){

        $striped_content = '';
        $content = '';

        $zip = zip_open($this->filename);

        if (!$zip || is_numeric($zip)) return false;

        while ($zip_entry = zip_read($zip)) {

            if (zip_entry_open($zip, $zip_entry) == FALSE) continue;

            if (zip_entry_name($zip_entry) != "word/document.xml") continue;

            $content .= zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));

            zip_entry_close($zip_entry);
        }// end while

        zip_close($zip);

        $content = str_replace('</w:r></w:p></w:tc><w:tc>', " ", $content);
        $content = str_replace('</w:r></w:p>', "\r\n", $content);
        $striped_content = strip_tags($content);

        return $striped_content;
    }

Parse .docx, .odt, .doc and .rtf documents

I wrote a library that parses the docx, odt and rtf documents based on answers here and elsewhere.

The major improvement I have made to the .docx and .odt parsing is the that the library processes the XML that describes the document and attempts to conform it to HTML tags, i.e. em and strong tags. This means that if you're using the library for a CMS, text formatting is not lost

You can get it here

My solution is Antiword for .doc and docx2txt for .docx

Assuming a linux server that you control, download each one, extract then install. I installed each one system wide:

Antiword: make global_install
docx2txt: make install

Then to use these tools to extract the text into a string in php:

//for .doc
$text = shell_exec('/usr/local/bin/antiword -w 0 ' . 
    escapeshellarg($docFilePath));

//for .docx
$text = shell_exec('/usr/local/bin/docx2txt.pl ' . 
    escapeshellarg($docxFilePath) . ' -');

docx2txt requires perl

no_freedom's solution does extract text from docx files, but it can butcher whitespace. Most files I tested had instances where words that should be separated had no space between them. Not good when you want to full text search the documents you're processing.

回答5:

Try ApachePOI. It works well for Java. I suppose you won't have any difficulties installing Java on Linux.

回答6:

I used docxtotxt to extract docx file content. My code is as follows:

if($extention == "docx")
{   
    $docxFilePath = "/var/www/vhosts/abc.com/httpdocs/writers/filename.docx";
    $content = shell_exec('/var/www/vhosts/abc.com/httpdocs/docx2txt/docx2txt.pl     
    '.escapeshellarg($docxFilePath) . ' -');
}

I insert little improvements in doc to txt converter function

private function read_doc() {
    $line_array = array();
    $fileHandle = fopen( $this->filename, "r" );
    $line       = @fread( $fileHandle, filesize( $this->filename ) );
    $lines      = explode( chr( 0x0D ), $line );
    $outtext    = "";
    foreach ( $lines as $thisline ) {
        $pos = strpos( $thisline, chr( 0x00 ) );
        if (  $pos !== false )  {

        } else {
            $line_array[] = preg_replace( "/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/", "", $thisline );

        }
    }

    return implode("\n",$line_array);
}

Now it saves empty rows and txt file looks row by row .

You can use Apache Tika as complete solution it provides REST API.

Another good library is RawText, as it can do an OCR over images, and extract text from any doc. It's non-free, and it works over REST API.

The sample code extracting your file with RawText:

$result = $rawText->extract($your_file)
