note 95993 added to domdocument.getelementsbytagname

Problem: You have an XML document that contains filename references to, say, images. Each filename reference is defined by <file>filename.ext</file> tag. You'd like to perform perform additional validation, say, after running the XML document through XSD validation. The additional validation can be any of your choice, in this example, it would be ideal to convert the PHP code to a function. The function would then determine if the images exist and return either an integer value or a boolean. <?xml version="1.0"?> <root> <box> <file>example.png</file> </box> <content> <item> <image><file>example2.png</file></image> <caption>The above image is an example</caption> </item> </content> </root> Solution: <?php $dom = new DomDocument(); $dom->prevservWhiteSpace = false; if (!@$dom->load("example.xml")) { echo "example.xml doesn't exist!\n"; return; } $imageList = $dom->getElementsByTagName('file'); $imageCnt = $imageList->length; for ($idx = 0; $idx < $imageCnt; $idx++) { print $imageList->item($idx)->nodeValue . "\n"; } ?> The above PHP code could easily be turned into a function that returns an array of image filenames, an integer value relative to the number of images found, etc. Hope this is helpful. ---- Server IP: 192.41.40.227 Probable Submitter: 98.231.164.224 ---- Manual Page -- http://www.php.net/manual/en/domdocument.getelementsbytagname.php Edit -- https://master.php.net/note/edit/95993 Del: integrated -- https://master.php.net/note/delete/95993/integrated Del: useless -- https://master.php.net/note/delete/95993/useless Del: bad code -- https://master.php.net/note/delete/95993/bad+code Del: spam -- https://master.php.net/note/delete/95993/spam Del: non-english -- https://master.php.net/note/delete/95993/non-english Del: in docs -- https://master.php.net/note/delete/95993/in+docs Del: other reasons-- https://master.php.net/note/delete/95993 Reject -- https://master.php.net/note/reject/95993 Search -- https://master.php.net/manage/user-notes.php
