If there is a "iciba.xml" file, its content is as follows:

The code is as follows

Sky

Array;Array;

The church tower stood against the sky like a finger pointing towards heaven.
The church spire looks like a finger pointing to the sky against the sky.

A balloon floated across the sky.
The balloon floats across the sky.

A flash of lightning lit up the sky.

A bright moving object appeared in the sky at sunset.
At sunset, a moving shiny object appeared in the sky.

In PHP language we can use the following method to get the value we want:

$xmldata = simplexml_load_file("iciba.xml");

header("Content-Type: text/html; charset=UTF-8");
print_r($xmldata); //The first part www.111cn.net

$listcount = count($xmldata->sent);

for($i=0;$i<$listcount;$i++){ //Part 2
$dictlist = $xmldata->sent[$i];
echo "
Example:".$dictlist->orig;
echo "
Translation:".$dictlist->trans;
}
?>"Part 1" will output:

SimpleXMLElement Object
(
[@attributes] => Array
(
[num] => 219
[id] => 219
[name] => 219
)

[key] => sky

The code is as follows

echo $xml->town['id']."
parent:";
echo $xml->town['parent']."
";

echo "
循环读取:

foreach($xml->user as $users){ //有多个user，取得的是数组，循环输出
    echo "-------------------
