Example

XML file:

The code is as follows

Copy Code

<?xml version= "1.0" encoding= "Iso-8859-1"?>
<note>
<to>George</to>
<from>John</from>
<body>don ' t forget the meeting!</body>
</note>

PHP Code:

<?php
if (file_exists (' Test.xml '))
{
$xml = simplexml_load_file (' Test.xml ');
Var_dump ($xml);
}

Else
{
Exit (' Error. ');
}
?>

Output:

Object (SimpleXMLElement) #1 (4)
{
["To"]=> string (4) "George"
[' From ']=> string (4) ' John '
["Heading"]=> string (8) "Reminder"
["Body"]=> string "Don t forget the meeting!"
}

If there is a "iciba.xml" document, its contents are as follows:

The code is as follows

Copy Code

<?xml version= "1.0" encoding= "UTF-8"?>
<dict num= "219" id= "219" name= "219" >
<key> Sky </key>
<pos></pos>
<acceptation>Array;Array;</acceptation>
<sent>
<orig>the church tower stood against the sky like a finger pointing towards
The spire of the <trans> church is like a finger pointing to the sky against the backdrop of the sky. </trans>
</sent>
<sent>
<orig>a balloon floated across the sky.</orig>
<trans> balloons float across the sky. </trans>
</sent>
<sent>
<orig>a bolt of lightning lit up the sky.</orig>
<trans> (a) lightning lights up the sky. </trans>
</sent>
<sent>
<orig>a Bright Moving object appeared in the sky at sunset.</orig>
<trans> Sunset, a moving shiny object appeared in the sky. </trans>
</sent>
<sent>
<orig>a Bright Rainbow Arched above.</orig>
<trans> a bright rainbow hangs in the sky. </trans>
</sent>
</dict> in the PHP language we can get the values we want in the following ways:

<?php
$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 II
$dictlist = $xmldata->sent[$i];
echo " Example:". $dictlist->orig;
echo " Translation:". $dictlist->trans;
}
?> the "first part" will output:

SimpleXMLElement Object
(
[@attributes] => Array
(
[Num] => 219
[ID] => 219
[Name] => 219
)

[Key] => Sky
[POS] => simplexmlelement Object
(
)

    [acceptation] => array;array
    [sent] => Array
         (
            [0] => SimpleXMLElement Object
               (
                     [orig] => the church tower stood against the sky like a finger pointing towards.
                     [Trans] the steeple of the => church is like a finger pointing to the sky against the sky.
               )

            [1] => simplexmlelement Object
               (
                     [orig] => A Balloon floated across the sky.
                     [trans] => balloons float across the sky.
               )

            [2] => simplexmlelement Object
               (
                     [orig] => A Bolt of lightning lit up the sky.
                     [Trans] => (together) lightning illuminates the sky.
               )

            [3] => simplexmlelement Object
               (
                     [orig] => A Bright moving object appeared in the sky at sunset.
                     [Trans] => sunset, a moving shiny object appeared in the sky.
               )

[4] => simplexmlelement Object
(
[orig] => A bright rainbow arched above.
[Trans] => a bright rainbow hangs in the sky.
)

)

The steeple of the church is like a finger pointing to the sky against the sky.
Example: A balloon floated across the sky.
The balloon floats across the sky.
