assertEqualXMLStructure()

assertEqualXMLStructure(DOMElement $expectedElement, DOMElement $actualElement[, boolean $checkAttributes = FALSE, string $message = ''])

当 $actualElement 中 DOMElement 的 XML 结构与 $expectedElement 中 DOMElement的 XML 结构不相同时报告错误，错误讯息由 $message 指定。

<?php
class EqualXMLStructureTest extends PHPUnit_Framework_TestCase
{
    public function testFailureWithDifferentNodeNames()
    {
        $expected = new DOMElement('foo');
        $actual = new DOMElement('bar');
 
        $this->assertEqualXMLStructure($expected, $actual);
    }
 
    public function testFailureWithDifferentNodeAttributes()
    {
        $expected = new DOMDocument;
        $expected->loadXML('<foo bar="true" />');
 
        $actual = new DOMDocument;
        $actual->loadXML('<foo/>');
 
        $this->assertEqualXMLStructure(
          $expected->firstChild, $actual->firstChild, TRUE
        );
    }
 
    public function testFailureWithDifferentChildrenCount()
    {
        $expected = new DOMDocument;
        $expected->loadXML('<foo><bar/><bar/><bar/></foo>');
