　 XML has been gradually replaced by JSON. The APIs used now all use JSON, but some old websites still use XML.

　The default xml file here is: address.xml, which is stored in the same level directory as the read php file. The xml content is as follows:

<?xml version="1.0" encoding="utf-8"?>
<note>
    <name>簡慶旺</name>
    <address>福建省漳州市南靖縣梅林鎮(zhèn)官洋村</address>
    <tel>17095921320</tel>
    <code>363609</code>
    <school>
        <highschool>
            <name>永定一中</name>
            <address>福建省龍巖市永定區(qū)91路</address>
        </highschool>
        <university>
            <name>吉首大學(xué)</name>
            <address>湖南省吉首市人民南路120號</address>
        </university>
    </school>
