Question

我正在尝试提供一种解决方案，允许用户上传启用邮件合并功能的Word DOCX模板文件。理想情况下，系统将读取DOCX文件，提取XML，查找邮件合并字段并将其保存到数据库中以便在路上进行映射。我可能会使用诸如Zend LiveDocX或PHPDOCX之类的SOAP服务或完全不同的东西 - 但是现在我需要弄清楚如何识别DOCX文件中的字段。为此，我从这篇文章开始：http://dfmaxwell.wordpress.com/2012/02/24/using-php-to-process-a-word-document-mail-merge/

我已经根据我的需要调整了一些（这可能是一个问题，虽然我也得到了与原始代码相同的错误。）特别是我此时并没有使用它来执行邮件合并，我只想识别字段。这就是我所拥有的：

    $newFile = '/var/www/mysite.com/public_html/template.docx';

    $zip = new ZipArchive();
    if( $zip->open( $newFile, ZIPARCHIVE::CHECKCONS ) !== TRUE ) { echo 'failed to open template'; exit; }
    $file = 'word/document.xml';
    $data = $zip->getFromName( $file );
    $zip->close();

    $doc = new DOMDocument();
    $doc->loadXML( $data );
    $wts = $doc->getElementsByTagNameNS('http://schemas.openxmlformats.org/wordprocessingml/2006/main', 'fldChar');

    $mergefields = array();

    function getMailMerge(&$wts, $index) {
        $loop = true;
        $counter = $index;
        $startfield = false;
        while ($loop) {
            if ($wts->item($counter)->attributes->item(0)->nodeName == 'w:fldCharType') {
                $nodeName = '';
                $nodeValue = '';
                switch ($wts->item($counter)->attributes->item(0)->nodeValue) {
                    case 'begin':
                        if ($startfield) {
                            $counter = getMailMerge($wts, $counter);
                        }
                        $startfield = true;
                        if ($wts->item($counter)->parentNode->nextSibling) {
                            $nodeName = $wts->item($counter)->parentNode->nextSibling->childNodes->item(1)->nodeName;
                            $nodeValue = $wts->item($counter)->parentNode->nextSibling->childNodes->item(1)->nodeValue;
                        }
                        else {
                            // No sibling
                            // check next node
                            $nodeName = $wts->item($counter + 1)->parentNode->previousSibling->childNodes->item(1)->nodeName;
                            $nodeValue = $wts->item($counter + 1)->parentNode->previousSibling->childNodes->item(1)->nodeValue;
                        }
                        if (substr($nodeValue, 0, 11) == ' MERGEFIELD') {
                            $mergefields[] = strtolower(str_replace('"', '', trim(substr($nodeValue, 12))));
                        }
                        $counter++;
                    break;
                case 'separate':
                    $counter++;
                    break;
                case 'end':
                    if ($startfield) {
                        $startfield = false;
                    }
                    $loop = false;
                }
            }
        }
        return $counter;
    }

    for ($x = 0; $x < $wts->length; $x++) {
        if ($wts->item($x)->attributes->item(0)->nodeName == 'w:fldCharType' && $wts->item($x)->attributes->item(0)->nodeValue == 'begin') {
            $newcount = getMailMerge($wts, $x);
            $x = $newcount;
        }
    }

使用ZipArchive（）打开DOCX文件没问题，如果我使用print_r（$ doc-＆gt; saveHTML（））;我看到XML数据就好了。问题是，当我执行我的代码时，我得到致命错误：在指向此对象的非对象上调用成员函数item（）：

$nodeName = $wts->item($counter)->parentNode->nextSibling->childNodes->item(1)->nodeName;

谷歌在试图找出这个错误时让我失望，有人能指出我正确的方向吗？提前谢谢！

找到了一个解决方案 - 它并不像我希望的那样优雅，但这里也是如此。

使用xml_parser_create_ns我可以在DOCX文件中搜索我需要的密钥，特别是“HTTP://SCHEMAS.OPENXMLFORMATS.ORG/WORDPROCESSINGML/2006/MAIN:INSTRTEXT”，它标识标记为“MERGEFIELD”的所有字段。然后我可以将结果转储到数组中并使用它们来更新数据库。即：

    // Word file to be opened
    $newFile = '/var/www/mysite.com/public_html/template.docx';

    // Extract the document.xml file from the DOCX archive
    $zip = new ZipArchive();
    if( $zip->open( $newFile, ZIPARCHIVE::CHECKCONS ) !== TRUE ) { echo 'failed to open template'; exit; }
    $file = 'word/document.xml';
    $data = $zip->getFromName( $file );
    $zip->close();

    // Create the XML parser and create an array of the results
    $parser = xml_parser_create_ns();
    xml_parse_into_struct($parser, $data, $vals, $index);
    xml_parser_free($parser);

    // Cycle the index array looking for the important key and save those items to another array
    foreach ($index as $key => $indexitem) {
        if ($key == 'HTTP://SCHEMAS.OPENXMLFORMATS.ORG/WORDPROCESSINGML/2006/MAIN:INSTRTEXT') {
            $found = $indexitem;
            break;
        }
    }

    // Cycle *that* array looking for "MERGEFIELD" and grab the field name to yet another array
    // Make sure to check for duplicates since fields may be re-used
    if ($found) {
        $mergefields = array();
        foreach ($found as $field) {
            if (!in_array(strtolower(trim(substr($vals[$field]['value'], 12))), $mergefields)) {
                $mergefields[] = strtolower(trim(substr($vals[$field]['value'], 12)));
            }
        }
    }

    // View the fruits of your labor
    print_r($mergefields);

无法使用PHP和DOM从Word DOCX中提取mailmerge字段
