范例

示例 #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();
?>

以上例程会输出:

<?xml version="1.0"?>
<p>before <a>element</a>
after</p>

注释

注意:

The indent is reset when an xmlwriter is opened.
