使用PHP SimpleXml解析XML文档的故障排除
使用PHP SimpleXml解析XML文档的故障排除
提问于 2011-12-14 07:30:16
我以前使用过xpath来处理XML元素，但是我一直在努力为这个特定的XML找到正确的语法。
我正在尝试解析守护应用程序接口响应。回复示例：
<response user-tier="approved" current-page="1" start-index="1" page-size="10" pages="1" total="10" status="ok">
<results>
<tag type="series" web-title="Cycling" section-name="Life and style" id="lifeandstyle/series/cycling" api- url="http://content.guardianapis.com/lifeandstyle/series/cycling" section-id="lifeandstyle" web- url="http://www.guardian.co.uk/lifeandstyle/series/cycling"/>
<tag type="keyword" web-title="Cycling" section-name="Sport" id="sport/cycling" api- url="http://content.guardianapis.com/sport/cycling" section-id="sport" web- url="http://www.guardian.co.uk/sport/cycling"/>
<tag type="keyword" web-title="Cycling" section-name="Life and style" id="lifeandstyle/cycling" api-url="http://content.guardianapis.com/lifeandstyle/cycling" section-id="lifeandstyle" web-url="http://www.guardian.co.uk/lifeandstyle/cycling"/>
<results>
<response>这是我第一次尝试用PHP编写代码(我是用cURL连接的)：
$news_items = new SimpleXMLElement($result); //loads the result of the cURL into a simpleXML response
$news_items = $guardian_response->xpath('results');
foreach ($news_items as $item) { //for each statement every entry will load the news_item and the web_url for the document
$item_block = "<p class=\"web_title\">";
$item_block = "<p class=\"web_url\">";
}它不能检索任何东西，我的代码中有什么缺陷吗？

<?php
function getAttribute($object, $attribute) {
foreach($object->attributes() as $a => $b) {
if ($a == $attribute) { $return = $b; }
}
if($return) { return $return; }
}
try {
$xml = simplexml_load_file( "parse.xml" );
/* Pay attention to the XPath, include all parents */
$result = $xml->xpath('/response/results/tag');
while(list( , $node) = each($result)) {
echo getAttribute( $node, "type" );
}
} catch( Exception $e ) {
echo "Exception on line ".$e->getLine()." of file ".$e->getFile()." : ".$e->getMessage()."<br/>";
