PHP Change text in Openoffice xml with Xmlreader and Xmlwriter

Question

I need to change the contents of the tags of an openoffice document and copy the rest of the document contents. The problem is not finding the tag and replacing its content, but copying the parent tags and their attributes correctly, using xmlreader and xmlwriter. Below a draft of the code:

Texts.xml

<texts>
 <text id="1">Lorem Ipsum</text>
 <text id="2">dolor sit amet</text>
 <text id="3">consectetur adipiscing elit. </text>
 <text id="4">Nunc vel justo vitae risus fermentum</text>
</texts>

Document.xml (example taken from officeopenxml.com)

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
<w:document xmlns:ve="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml">

     <w:t>Humpty Dumpty</w:t></w:r><w:r><w:t xml:space="preserve">.     </w:t>
   </w:r>
 </w:p>
 <w:p>
  <w:pPr>
  <w:spacing w:before="120" w:after="120"/>
  <w:ind w:left="720" w:right="720"/>
  <w:rPr>
   <w:sz w:val="18"/>
   </w:rPr>
 </w:pPr>
  <w:r>
  <w:rPr>
  <w:sz w:val="18"/>
  </w:rPr>
   <w:t xml:space="preserve">Humpty Dumpty sat on a wall. </w:t>
   </w:r>
 . . .
 </w:p>
</w:body>
</w:document>

PHP

$original = new XMLReader;
$source = new XMLReader;
$original->open('document.xml');
$source->open('texts.xml')
$writer = new XMLWriter();
$writer->openURI('new_dpcument.xml');
$writer->setIndent(true);
$writer->startDocument("1.0");
$t = 0;
while ($original->read()){
 if ($original->nodeType == XMLREADER::ELEMENT && $original->name !== 'w:t'){ 
  //while the node isn't text node (<w:t>), I'd like to copy everything as is to the new_document.xml. I can just use $content = $original->readOuterXML(); and $writer->writeRaw($content); for nodes not related to w:t,  but it won't work for w:t parent nodes.
}elseif ($original->nodeType == XMLREADER::ELEMENT && $original->name === 'w:t'){
//now that it's a w:t I need to replace its content.
$source->next('text');
$content = $source->readInnerXML($source);
$writer->startElement('w:t');
 $writer->text($content); 
$writer->endElement();
}
}
$writer->endDocument();
$writer->flush();

The result should be something like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

Answer 1

I managed to settle with an answer from Soen.

I’m using the class for this Xmlreaderiterator version 0.1.8

Below the code:

require('xmlreader-iterators.php'); // require XMLReaderIterator library

$xmlInputFile = 'data/worddocument.xml';
$xmlXliffFile = 'data/segments.xliff';

$reader = new XMLReader();
$reader->open($xmlInputFile);

$writer = new XMLWriter();
$writer->openMemory();

$iterator = new XMLWritingIteration($writer, $reader);

$writer->startDocument();

$textCount = 0;
foreach ($iterator as $node) {
    $isElement = $node->nodeType === XMLReader::ELEMENT;

    if ($isElement && $node->name === 'w:t') {
        $textCount++;

        $writer->startElement($node->name);

        $node->next();
        $iterator->skipNextRead();

        $writer->text(sprintf("TEXT #%d", $textCount));
        $writer->endElement();
    } else {
        // handle everything else
        $iterator->write();
    }
}

$writer->endDocument();
echo $writer->outputMemory(true);
