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>
Note:
The indent is reset when an xmlwriter is opened.
