rss Feed类似的内容。我指的是包含XML内容的网站，其中包含一些重要信息。
XML的简单输入（有十几个条目）如下所示：
<?xml version='1.0' encoding='UTF-8'?>
<nvd xmlns:scap-core="http//0.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:patch="http//patch/0.1" xmlns="http//obj/0.1" xmlns:lang="http//lang/2.0" xmlns:cvss="http//cvss-v2/0.2" xmlns:object="http//object/0.4" nvd_xml_version="2.0" pub_date="2014-02-25T10:00:00" xsi:schemaLocation="http//patch/0.1 http//schema/patch_0.1.xsd http//0.1 http//schema/scap-core_0.1.xsd http//obj/0.1 http//schema/nvd-cve-feed_2.0.xsd">
<entry id="0528">
<object:configuration id="site.com/">
<lang:logical-test negate="false" operator="OR">
<lang:fact-ref name="version:2.6.0"/>
<lang:fact-ref name="version:2.6.1"/>
<lang:fact-ref name="version:2.6.2"/>
<lang:fact-ref name="version:2.6.3"/>
</lang:logical-test>
</object:configuration>
<object:list>
<object:product>version:2.6.3</object:product>
<object:product>version:2.6.0</object:product>
<object:product>version:2.6.1</object:product>
<object:product>version:2.6.2</object:product>
</object:list>
<object:id>0528</object:id>
<object:published-datetime>2014-02-17T11:55:04.787-05:00</object:published-datetime>
<object:last-modified-datetime>2014-02-21T09:14:10.780-05:00</object:last-modified-datetime>
<object:cwe id="264"/>
</entry>
我想阅读此XML以便将这些值放入我的数据库中。我的方法就是这样：
$ch = curl_init();
if (FALSE === $ch)
throw new Exception('failed to initialize');
curl_setopt($ch, CURLOPT_URL,"internal.adres.com");
curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
$xml = new SimpleXMLElement($content);
foreach ($xml as $obj){
var_dump($obj);
break;
}
这就是魔术发生的地方。当我执行var_dump($xml)时，我会获得对象列表，但这些对象只有id字段（其他字段如product或datetime都缺失）
var_dump($obj)的结果如下：
object(SimpleXMLElement)#3 (1) { ["@attributes"]=> array(1) { ["id"]=> string(13) "0528" } }
如何获取此xml的所有字段？
答案 0 :(得分：0)
您正在查看<entry>字段的属性。 <entry>
<obj>
答案 1 :(得分：0)
简化您提供的XML（删除命名空间，更正closign标记并为其添加标题），我将以下示例放在一起。
它显示了一些可用于访问文档中的属性和节点的不同方法。
简而言之：
$node['id'] $node->subNode或foreach( $node->subNode as $subNode ) $node->subNode[0]['id'] 我希望以下示例对您的结构有意义......
<?
$content = '<?xml version="1.0"?>
<entries>
<entry id="0528">
<configuration id="google.com">
<logical negate="false" operator="OR">
<fact name="1.0.0"/>
</logical>
</configuration>
<list>
<product>1.0.0</product>
</list>
<id>0528</id>
<datetime>2014-02-17T11:55:04.787-05:00</datetime>
<last-modified-datetime>2014-02-21T09:14:10.780-05:00</last-modified-datetime>
</entry>
</entries>';
$xml = new SimpleXMLElement($content);
foreach ($xml as $entry){
// attributes can be referenced as array elements
$entryId = $entry['id'];
echo( "Entry id is {$entryId}\r\n" );
// Sub-nodes can be referenced as member variables and looped over
foreach( $entry->configuration as $configuration ) {
$configurationId = $configuration['id'];
echo( "Configuration id is {$configurationId}\r\n" );
foreach( $configuration->logical as $logical ) {
// You can string the methods together like this:
$factName = $logical->fact[0]['name'];
echo( "Logical fact name = $factName" );
}
}
}
?>
根据更新的问题，问题似乎与命名空间有关。
你可以剥离这些定义......
虽然这可能不是推荐的方式（注册命名空间可能是要走的路，但它们似乎没有有效的URI，所以这可能不是一个选项）。
我的例子变成：
<?
$content = '<?xml version=\'1.0\' encoding=\'UTF-8\'?>
<nvd xmlns:scap-core="http//0.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:patch="http//patch/0.1" xmlns="http//obj/0.1" xmlns:lang="http//lang/2.0" xmlns:cvss="http//cvss-v2/0.2" xmlns:object="http//object/0.4" nvd_xml_version="2.0" pub_date="2014-02-25T10:00:00" xsi:schemaLocation="http//patch/0.1 http//schema/patch_0.1.xsd http//0.1 http//schema/scap-core_0.1.xsd http//obj/0.1 http//schema/nvd-cve-feed_2.0.xsd">
<entry id="0528">
<object:configuration id="site.com/">
<lang:logical-test negate="false" operator="OR">
<lang:fact-ref name="version:2.6.0"/>
<lang:fact-ref name="version:2.6.1"/>
<lang:fact-ref name="version:2.6.2"/>
<lang:fact-ref name="version:2.6.3"/>
</lang:logical-test>
</object:configuration>
<object:list>
<object:product>version:2.6.3</object:product>
<object:product>version:2.6.0</object:product>
<object:product>version:2.6.1</object:product>
<object:product>version:2.6.2</object:product>
</object:list>
<object:id>0528</object:id>
<object:published-datetime>2014-02-17T11:55:04.787-05:00</object:published-datetime>
<object:last-modified-datetime>2014-02-21T09:14:10.780-05:00</object:last-modified-datetime>
<object:cwe id="264"/>
</entry>
</nvd>';
$content = preg_replace('/xmlns[^=]*="[^"]*"/i', '', $content);
// Gets rid of all namespace references
$content = preg_replace('/[a-zA-Z]+:([a-zA-Z]+[\W=>])/', '$1', $content);
$xml = new SimpleXMLElement($content);
foreach ($xml as $entry){
// attributes can be referenced as array elements
$entryId = $entry['id'];
echo( "Entry id is {$entryId}\r\n" );
// Sub-nodes can be referenced as member variables and looped over
foreach( $entry->configuration as $configuration ) {
$configurationId = $configuration['id'];
echo( "Configuration id is {$configurationId}\r\n" );
// Note for hyphenated nodes you need to wrap in quotes and curlies
foreach( $configuration->{'logical-test'} as $logical ) {
$testOperator = $logical['operator'];
echo( "Test Operator = $testOperator\r\n" );
// You can string the methods together like this:
$factName = $logical->{'fact-ref'}[0]['name'];
echo( "Logical fact name = $factName\r\n" );
}
}
}
?>
哪个输出：
Entry id is 0528
Configuration id is site.com/
Test Operator = OR
Logical fact name = version:2.6.0
请注意，为了访问名称中带有连字符的节点，您需要包含curlies和quotes。例如。 $logical->{'fact-ref'}
