note 126739 added to xmlreader.expand

XMLReader::expand() expands the current subtree to DOM. SimpleXML is good too. To avoid a warning like "Imported Node must have associated Document" when using simplexml_import_dom(), we can do : <?php // Huge XML compressed file $xml = XMLReader::open('compress.zlib:///path/to/my-data.xml.gz'); // Targeting a tiny subtree while ($xml->name !== 'my-targeted-element') { $xml->read(); } // The trick is here... // Subtree is expanded in an empty document... $dom = $xml->expand(new DOMDocument()); // ... which can be imported by SimpleXML $sx = simplexml_import_dom($dom); // We can now process our tiny subtree with SimpleXML $sx ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 2a01:e0a:968:1840:d166:44e4:8afa:c08) ---- Manual Page -- https://php.net/manual/en/xmlreader.expand.php Edit -- https://main.php.net/note/edit/126739 Del: integrated -- https://main.php.net/note/delete/126739/integrated Del: useless -- https://main.php.net/note/delete/126739/useless Del: bad code -- https://main.php.net/note/delete/126739/bad+code Del: spam -- https://main.php.net/note/delete/126739/spam Del: non-english -- https://main.php.net/note/delete/126739/non-english Del: in docs -- https://main.php.net/note/delete/126739/in+docs Del: other reasons-- https://main.php.net/note/delete/126739 Reject -- https://main.php.net/note/reject/126739 Search -- https://main.php.net/manage/user-notes.php
