Previous Comments: ------------------------------------------------------------------------ [2007-05-02 07:37:18] daniel dot oconnor at gmail dot com Description: ------------ DOMDocument should extend DOMNode (http://www.w3.org/TR/DOM-Level-3-Core/core.html#i-Document), and should be able to find any xmlns defined in the top level element. Currently, DOMDocument->lookupPrefix() and DOMDocument->lookupNamespaceURI() will never return any values other than null; or warn developers they are using the wrong method. Additionally, DOMDocument->lookupPrefix & friends should be able to recognise xmlns defined in the root node of a document. Reproduce code: --------------- <?php $xml = '<?xml version="1.0" encoding="UTF-8"?> <office:document-content office:class="text" office:version="1.0" xmlns:chart="http://openoffice.org/2000/chart" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:dom="http://www.w3.org/2001/xml-events" xmlns:dr3d="http://openoffice.org/2000/dr3d" xmlns:draw="http://openoffice.org/2000/drawing" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:form="http://openoffice.org/2000/form" xmlns:math="http://www.w3.org/1998/Math/MathML" xmlns:meta="http://openoffice.org/2000/meta" xmlns:number="http://openoffice.org/2000/datastyle" xmlns:office="http://openoffice.org/2000/office" xmlns:ooo="http://openoffice.org/2004/office" xmlns:oooc="http://openoffice.org/2004/calc" xmlns:ooow="http://openoffice.org/2004/writer" xmlns:script="http://openoffice.org/2000/script" xmlns:style="http://openoffice.org/2000/style" xmlns:svg="http://www.w3.org/2000/svg" xmlns:table="http://openoffice.org/2000/table" xmlns:text="http://openoffice.org/2000/text" xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <office:body> <table:table table:name="Table13" table:style-name="Table13"> <table:table-column table:style-name="Table13.A" /> <table:table-row table:style-name="Table13.1"> <table:table-cell table:style-name="Table13.A1" table:value-type="string"> <text:p text:style-name="P84">Important Notes and Qualifications</text:p> </table:table-cell> </table:table-row> </table:table> <text:p text:style-name="P88">&lt; &lt; func_image(photograph) &gt; &gt;</text:p> </office:body> </office:document-content>'; $document = new DOMDocument('1.0', 'UTF-8'); $document->loadXML($xml); foreach ($document->getElementsByTagNameNS('http://openoffice.org/2000/table', 'table') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } print "\n\n"; foreach ($document->getElementsByTagName('*') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } print "\n\n"; foreach ($document->getElementsByTagNameNS('*', '*') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } print "\n\n"; foreach ($document->getElementsByTagNameNS('http://openoffice.org/2000/table', '*') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } print "\n\n"; foreach ($document->getElementsByTagNameNS('http://openoffice.org/2000/table', '*') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } print "\n\n"; foreach ($document->getElementsByTagNameNS('http://openoffice.org/2000/table', 'table') as $element) { echo 'local name: ', $element->localName, ', prefix: ', $element->prefix, ' xmlns (element):', $element->lookupNamespaceURI($element->prefix), ' xmlns (document):', $document->lookupNamespaceURI($element->prefix), "\n"; } Expected result: ---------------- $document->lookupNamespaceURI() and $element->lookupNamespaceURI() should return identical results. Actual result: -------------- local name: table, prefix: table xmlns (element):http://openoffice.org/2000/table xmlns (document): ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41257&edit=1
