在xml中未显示的整数的第一个上加倍零

i create a XML file using PHP and MYSQL . When i open XML file in notepad++ the content like below :

<?xml version="1.0" encoding="UTF-8"?>
<products>
    <item>
        <price>26000</price>
        <value>278</value>
        <code>00101189</code>
    </item>
    <item>
        <price>17000</price>
        <value>92</value>
        <code>00101100</code>
    </item>
    <item>
        <price>119000</price>
        <value>112</value>
        <code>7228687815233</code>
    </item>
    <item>
        <price>48000</price>
        <value>400</value>
        <code>6954851217411</code>
    </item>
</products>

But when open this file in Microsoft Excel 2013 the content like this :

As you see at The second row in code column , code should be " 00101189 " but output is " 101189 " .

What is problem ? my XML file or Microsoft excel ?

Excel will automatically hide leading zeroes. Try opening in a text editor and hopefully everything will be intact!
