PHPword解析内容支撑

因有些功能不支持，所以新增了某些功能，以防后期变动不好变更，手动做个记录

1. 将公式替换成指定的符号，读取到 html 后读取 xml 解析公式，根据标记符号进行替换
   文件名PhpOffice\PhpWord\Shared\XMLReader.php

    public function getDomFromZip($zipFile, $xmlFile)
    {
        if (file_exists($zipFile) === false) {
            throw new \Exception('Cannot find archive file.');
        }

        $zip = new \ZipArchive();
        $zip->open($zipFile);
        $content = $zip->getFromName($xmlFile);
        $zip->close();

        if ($content === false) {
            return false;
        }
        if($xmlFile === 'word/document.xml'){
            // 字符串替换,将公式替换成$Math$
            $content = preg_replace('/[\s|\S]*?<\/m:oMath>/', '$Math$', $content);
            // 后续在将$Math$标记替换为对应的处理过的mathml公式（或latex表达式、公式图片）
            
        }

        return $this->getDomFromString($content);
    }

公式转换传送大飞机来咯！

2. 表格的单元格宽度的单位
   文件名PhpOffice\PhpWord\Reader\Word2007\AbstractPart.php

protected function readTable(){
  //...
                foreach ($rowNodes as $rowNode) {
                    if ('w:trPr' == $rowNode->nodeName) { // Row style
                        // @todo Do something with row style
                    } elseif ('w:tc' == $rowNode->nodeName) { // Cell
                        $cellWidth = $xmlReader->getAttribute('w:w', $rowNode, 'w:tcPr/w:tcW');
                        $cellStyle = null;
                        $cellStyleNode = $xmlReader->getElement('w:tcPr', $rowNode);
                        if (!is_null($cellStyleNode)) {
                            $cellStyle = $this->readCellStyle($xmlReader, $cellStyleNode);
                        }
                        $cell = $row->addCell($cellWidth, $cellStyle);

                        // ----------以下为新增部分
                        // 设置单位
                        $cellUnit = $xmlReader->getAttribute('w:type', $rowNode, 'w:tcPr/w:tcW');
                        $cell->setUnit($cellUnit);
                        // ----------以上为新增部分

                        $cellNodes = $xmlReader->getElements('*', $rowNode);
                        foreach ($cellNodes as $cellNode) {
                            if ('w:p' == $cellNode->nodeName) { // Paragraph
                                $this->readParagraph($xmlReader, $cellNode, $cell, $docPart);
                            }
                        }
                    }
                }
            }

  //...

3. 内容的对齐样式
   文件名Element\AbstractContainer.php

    protected function addElement($elementName)
    {
        $elementClass = __NAMESPACE__ . '\\' . $elementName;
        $this->checkValidity($elementName);

        // Get arguments
        $args = func_get_args();
        $withoutP = in_array($this->container, array('TextRun', 'Footnote', 'Endnote', 'ListItemRun', 'Field'));
        if ($withoutP && ($elementName == 'Text' || $elementName == 'PreserveText')) {
            // 此处不知道为何要把样式移除，移除后的段落无alignment样式了,故把此代码注释了，不知会有何遗留问题，待发现。
            // $args[3] = null; // Remove paragraph style for texts in textrun
        }
        // ........
    }

4. 新增首行缩进功能
   文件Style\Paragraph.php

    /**
     * 缩进字符
     *
     * @var integer
     * @Author 
     * @DateTime 2022-11-03
     */
    private $firstLineChars = 0; //新增属性

    // 修改方法
    public function getStyleValues()
    {
        $styles = array(
            // ...
            'indentation'         => $this->getIndentation(),
            // ------新增内容开始
            'firstLineChars'      => $this->getFirstLineChars(),
            // ------新增内容结束
            'spacing'             => $this->getSpace(),
            'pagination'          => array(
                'widowControl'    => $this->hasWidowControl(),

            ),
           // ...
        );
        return $styles;
    }

    新增方法
    /**
     * Get getFirstLineChars
     *
     * 
     */
    public function getFirstLineChars()
    {
        return $this->firstLineChars;
    }
    /**
     * Set getFirstLineChars
     *
     * 
     */
    public function setFirstLineChars($num = 0)
    {
