Pull XML data from excel file

[bae95]

I'm looking to find a way to properly extract all relevant xml data from an excel file. I found a similar example using PHPWord where xml of a table is being grabbed from a word document like this;

    //Create table
    $document_with_table = new PhpWord();
    $section = $document_with_table->addSection();
    $table = $section->addTable();
    for ($r = 1; $r <= 8; $r++) {
    $table->addRow();
    for ($c = 1; $c <= 5; $c++) {
        $table->addCell(1750)->addText("Row {$r}, Cell {$c}");
      }
    }

// Create writer to convert document to xml
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($document_with_table, 'Word2007');

// Get all document xml code
$fullxml = $objWriter->getWriterPart('Document')->write();

// Get only table xml code
$tablexml = preg_replace('/^[\s\S]*(<w:tbl\b.*<\/w:tbl>).*/', '$1', $fullxml);

I'm trying to see if there is a similar approach that can be used with PHPSpreadsheet.
The end goal would be to grab a table from excel file and insert it into word template. I want to see if there is something in PHPSpreadsheet that exists that would mimic:

    // Get all document xml code
    $fullxml = $objWriter->getWriterPart('Document')->write();

.... in order to retrieve the table information in xml for the purpose of writing it to a word document with PHPWord's template processor as an end goal.
