When you generate an XML time, if that is to say when it will return an empty element of it is empty of the tag <test />, how to convert <test> </test>it?
In XML, they are considered to be the exact same thing, any parser should recognize both forms. However, sometimes this is the case required format through the LIBXML_NOEMPTYTAGconstant passed to DOMdocumentthe saveXML()change its methods.
How to display two markers in the space-time node content ???
<?php
$dom = new \DOMDocument('1.0');
$document = $dom->createElement('document');
$document = $dom->appendChild($document);
$head = $dom->createElement('title','this is title');
$content = $dom->createElement('content','');
$document->appendChild($head);
$document->appendChild($content);
echo $dom->saveXML();
?>
In XML, they are considered to be the exact same thing, any parser should recognize both forms. However, if you still need, you can write
<?php
echo $dom->saveXML($dom->documentElement, LIBXML_NOEMPTYTAG);
?>
输出1：
<?xml version="1.0"?>
<document>
<title>this is title</title>
<content/>
</document>
输出2：
<document>
<title>this is test</title>
<content></content>
</document>
Example of use:
DOMDocument :: saveXML
