Doc with OLEObject leads to "Undefined namespace prefix"

[maks-rafalko]

Describe the Bug

When the doc has an image as OLEObject, opening such document with phpword leads to warning:

Warning: DOMXPapth::query(): Undefined namespace prefix

It fails here:

PHPWord/src/PhpWord/Shared/XMLReader.php

Line 107 in aca1078

return $this->xpath->query($path, $contextNode);

and this function is called from:

PHPWord/src/PhpWord/Reader/Word2007/AbstractPart.php

Line 284 in aca1078

$rId = $xmlReader->getAttribute('r:id', $node, 'o:OLEObject');

Steps to Reproduce

<?php
require __DIR__ . '/vendor/autoload.php';

$filePath = __DIR__ . '/broken.docx'`; // see attached document

\PhpOffice\PhpWord\IOFactory::load($filePath, 'Word2007');

broken.docx

Expected Behavior

No errors are thrown.

Current Behavior

Currently, warning produces an exception and script fails during loading the file by phpword.

I tried to analyze what is going on, if this helps, this is an XML (simplified, full is inside attached docx) that is being processed during the failure:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
    <w:body>

            <w:r>
                <w:object w:dxaOrig="8640" w:dyaOrig="5760">
                    <v:rect id="rectole0000000000" style="width:432.000000pt;height:288.000000pt" o:preferrelative="t"
                            o:ole="" xmlns:o="urn:schemas-microsoft-com:office:office"
                            xmlns:v="urn:schemas-microsoft-com:vml">

                        <v:imagedata r:id="docRId1" o:title=""
                                     xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"/>
                    </v:rect>
                    <o:OLEObject Type="Embed" ProgID="StaticMetafile" DrawAspect="Content" ObjectID="0000000000"
                                 ShapeID="rectole0000000000" r:id="docRId0"
                                 xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"
                                 xmlns:o="urn:schemas-microsoft-com:office:office"/>
                </w:object>
            </w:r>
        </w:p>

    </w:body>
</w:document>

When phpword tries to get o:OLEObject inside w:object tag, it fails with the warning Warning: DOMXPapth::query(): Undefined namespace prefix
