Get attributes and values using SimpleXML
提问by Jeremy Dicaire
I really don't understand how to use SimpleXML in PHP.
我真的不明白如何在 PHP 中使用 SimpleXML。
Here is an exemple of my XML file:
这是我的 XML 文件的示例：
<?xml version="1.0" encoding="UTF-8" ?>
<eventlog version="1.1">
<event source="Firewall" timeStamp="1308433939" type="0" deleted="0" bodyLength="218">
<subject>Network access detected</subject>
<action>Allowed</action>
<message>The program c:\xampp\apache\bin\httpd.exe attempted to connect to the Internet. The program used the protocol TCP on port 80.</message>
</event>
</eventlog>
I need to retrieve this: Source, Timestamp, Subject, Action, Message
我需要检索这个：源、时间戳、主题、操作、消息
I just don't get it. Can someone please help me with this?
我只是不明白。有人可以帮我解决这个问题吗？

This code should work:
此代码应该工作：
$xml = new SimpleXMLElement($xmlString);
$source = $xml->event->attributes()->source;
$timestamp = $xml->event->attributes()->timestamp;
$subject = $xml->event->subject;
$action = $xml->event->action;
$message = $xml->event->message;
... where $xmlString is the string of the xml file.
... 其中 $xmlString 是 xml 文件的字符串。

In the interest of teaching you to fish, I'd encourage you to check out the PHP Docs on SimpleXML.

To help get your started though.
帮助您入门。
- Use
simplexml_load_file()orsimplexml_load_string()to parse your XML - This will return an object - use
var_dump()orprint_r()to see what it looks like. - Traverse this object to obtain the attributes you want.
- 使用
simplexml_load_file()或simplexml_load_string()解析您的 XML - 这将返回一个对象 - 使用
var_dump()或print_r()查看它的外观。 - 遍历这个对象来获取你想要的属性。

Try the following:
请尝试以下操作：
function time2DatetimeUS($timestamp)
{
$datetime = date('Y-m-d H:i:s', $timestamp);
return $datetime;
}
$db = new SQLiteDatabase("AutoAnalysis.sqlite", 0666, $err);
$xml = new SimpleXMLElement($logs_antivirus_local, NULL, TRUE);
foreach ($xml->event as $a) {
$source = $a->attributes()->source;
$timestamp = $a->attributes()->timeStamp;
$datetime = time2DatetimeUS("$timestamp");
$subject = $a->subject;
$action = $a->action;
$message = $a->message;
}
$query = "INSERT INTO BitDefender(id, datetime, module, sujet, action, message)
VALUES ('', '$datetime', '$source', '$subject', '$action', '$message')";
$results = $db->queryexec($query);
echo " $datetime $source $subject";
