Examples
Example #1 XMLWriter::setIndent() and mixed Content
Enabling indentation is not suitable for mixed content, because the indent string is also inserted before inline elements.
<?php
$writer = new XMLWriter();
$writer->openMemory();
$writer->setIndent(2);
$writer->startDocument();
$writer->startElement('p');
$writer->text('before');
$writer->writeElement('a', 'element');
$writer->text('after');
$writer->endElement();
$writer->endDocument();
echo $writer->outputMemory();
?>
The above example will output:
<?xml version="1.0"?> <p>before <a>element</a> after</p>
Notes
Note:
The indent is reset when an xmlwriter is opened.
