Answer 1

당신은 XML 파서 또는 SimpleXML을 사용할 수 있습니다. XPath에와

$xml = new SimpleXMLElement($yourXml); 

Answer 2

SimpleXML을 : http://www.php.net/manual/en/simplexmlelement.xpath.php

$xmlSrc =<<<XML 
<test> 
    <required> 
     <item type="binary"> 
      <name>binary name</name> 
      <url visibility="restricted">test.exe</url> 
     </item> 
     <item type="document" subtype="mytype"> 
      <name>doc test name</name> 
      <url visiblity="visible">my.pdf</url> 
     </item> 
    </required> 
    <optional> 
     <item type="document"> 
      <name>doc name1</name> 
      <url visiblity="visible">user_guide1.pdf</url> 
     </item> 
     <item type="document2"> 
      <name>doc name2</name> 
      <url visiblity="visible">user_guide2.pdf</url> 
     </item> 

     <item type="document3"> 
      <name>doc name3</name> 
      <url visiblity="visible">user_guide3.pdf</url> 
     </item> 
    </optional> 
    <dependencies> 
     <dependency> 
      <url>test4.xml</url> 
     </dependency> 
    </dependencies> 
</test> 
XML; 


$xml = new SimpleXMLElement($xmlSrc); 

$required_names = $xml->xpath('/test/required/item/name'); 
$optional_names = $xml->xpath('/test/optional/item/name'); 


print_r($required_names); 
print_r($optional_names);
