PHP read XML, there is a problem, thank you.

The XML file is:

 
  
  
   
    
   http://114.80.235.12
  
   
  
   
    
   http://114.80.236.202
  
   
  
   
 
  
 
  

My PHP code is written like this, but I can't read it. Thank you.

2. Read Xml$xml_array=simplexml_load_file ("Wc.xml"); Reads the data from the XML into the array object in the foreach ($xml _array as $temp) {echo '
";p Rint_r ($temp->f); echo"
";}

My goal is to read the middle of that two HTTP address. Thank you, sir.

Reply to discussion (solution)

Xpath= '//f[2]/text () '

Xpath= '//f[2]/text () '

Thank you, can I trouble you to say clearly, I Baidu a, no things

Print_r ($xml _array->a->f);

$s =<<< XML
 
  
  
   
    
   http://114.80.235.12
  
   
  
   
    
   http://114.80.236.202
  
   
  
    XML; $xml = simplexml_load_string ($s);//normal traversal, need to know exactly where the target node is at the level of foreach ($xml as $temp
 
   ) {  foreach ($temp->f as $v) echo "$v
 
  
   
  XPath ('//f ') as $v) echo" $v
  
   
";
 
  

All can be obtained
http://114.80.235.12
http://114.80.236.202

[code=php] $s =<<< XML


Thank you brother for helping. Wish you happy every day.
I would like to strengthen my study, what is this knowledge? What knowledge should I search? Thank you, sir.

If you Print_r ($xml _array); You can see

SimpleXMLElement Object (    [@attributes] = = Array        (            [TIME] = 180530            [vi] = 1            [ch] = 29            [NLS] = 0            [title] + [Control] [            code] = qt4j-61ws-q            [enable] + 1            [logo] + 0            [WT] = 0            [band] =& Gt 0        )    [a] = = SimpleXMLElement Object        (            [f] = = Array                (                    [0] =/http 114.80.235.12                    [1] = http://114.80.236.202                )        )    [b] = simplexmlelement Object        (        ))

Such a structure, it is easy to write code according to this. Don't repeat it.

XPath is a language that looks for information in an XML document. XPath is used to navigate through elements and attributes in an XML document.
You can search for XPath to find tutorials such as http://www.w3school.com.cn/xpath/

   DOMDocument (); $doc->loadxml ($s); $xpath = new Domxpath ($doc); $query = '//f[1]/text () '; $entries = $xpath Evaluate ($query, $doc);//foreach ($entries as $entry) var_dump ($entry), foreach ($entries as $entry) echo $entry->data ; $xml = simplexml_load_string ($s); foreach ($xml->xpath ('//f[1]/text () ') as $v) echo $v;? >

Uh, a second address? #1的才正确
f[2]/text ()
The XPath counter is starting from 1.
