我正在尝试使用PHP编辑一些XML。目前XML看起来像:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
<channel>
<title>Main Title</title>
<link>http://exmaple.com</link>
<description> blahblahblah </description>
<language>en</language>
<item>
<title>Tite1</title>
<link>http://www.example.com (THIS IS WHAT I WANT)</link>
<description>blah blah blah</description>
</item>
.
.
.
</channel>
</rss>
我尝试访问第二级链接,但我的代码只更改了第一个链接节点值。这是代码:
$xml->load('http://www.google.com/doodles/doodles.xml');
$element = $xml->getElementsByTagName('channel')->item(0);
$secondlvl = $element->getElementsByTagName('item')->item(0);
$2ndlevellinknode = $element->getElementsByTagName('link')->item(0);
$2ndlevellinknode->nodeValue = $newvalue;
有什么建议吗?也可以在像这样的for循环中使用这行代码
for ($i = 0; $i <= 20; $i++) {
$element = $xml->getElementsByTagName('channel')->item(0);
$secondlvl = $element->getElementsByTagName('item')->item(0);
$2ndlevellinknode = $element->getElementsByTagName('link')->item($i);
$2ndlevellinknode->nodeValue = $newvalue;
}
答案 0 :(得分:2)
这应该会给你一个想法。
$f = simplexml_load_file('test.xml');
print $f->channel->title . "\n";
print $f->channel->link . "\n";
print $f->channel->description . "\n";
foreach($f->channel->item as $item) {
print $item->title . "\n";
}
