Php获取xml中的节点值

转自:http://blog.163.com/163navy/blog/static/10530408620099126372974/

XML: test_xml2.xml

<?xml version="1.0" encoding="UTF-8"?>

<friends_get_response list="true" xmlns="http://api.xiaonei.com/1.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://api.xiaonei.com/1.0/ http://api.xiaonei.com/1.0/xiaonei.xsd">

       <uid>200032219</uid>

       <uid>84525914</uid>

        <uid>12345689</uid>

        <uid>98765432</uid>

</friends_get_response>

 

PHP代码1：

<?php

$doc=new DOMDocument();

$doc->load('test_xml2.xml');

$productProfile=$doc->getElementsByTagName('friends_get_response');

echo '<pre/>'

foreach($productProfile as $profile)

{

    //$productNames = $profile->getElementsByTagName("uid");

    //$productName  = $productNames->item(0)->nodeValue;

    //echo $productName;

    echo $profile->nodeValue;

}

?>

 

结果：  这样nodeValue，直接把节点中的所有值都取出来

        200032219

        84525914

        12345689

        98765432

 

PHP 代码2：

 <?php

    $doc = new DOMDocument();

    $doc->load('test_xml2.xml');

    $xiaoNei = $doc->getElementsByTagName( "friends_get_response" );

    $i=0;

    foreach($xiaoNei as $key ){

           $uid = $key->getElementsByTagName( "uid" );

       foreach ( $uid as $param) {

         echo $param -> nodeValue .'<br />'

     }

  }

?>

 

结果：这是得到friends_get_response->uid 节点的值

 

200032219

84525914

12345689

98765432

 

 

XML2： test_xml4.xml

<?xml version=Ƈ.0' standalone='yes'?>

<test>

  <a>aa</a>

  <b>

     <bb>bb1</bb>

     <bb>

       <bbb>bbb1</bbb>

        <bbb>bbb2</bbb>

     </bb>

  </b>

  <c>cc</c>

  <d>

    <f> ff </f>

  </d>

</test>

 

PHP代码：

<?php

echo '<pre/>'

  $doc = new DOMDocument();

  $doc->load( 'test_xml4.xml' );

  $xiaoNei = $doc->getElementsByTagName( "test" );

  foreach( $xiaoNei as $v)

  {

         echo $v->nodeValue.'<br />'

  }

?>

结果为：  使用nodeValue直接就得到test节点下面的  多层子节点的值

aa

     bb1

        bbb1

        bbb2 

  cc

     ff

PHP代码：

$xmlstr = <<<XML

<movies>

<movie>

  <title>PHP: Behind the Parser</title>

XML; 

$xml = simplexml_load_string($xmlstr);

echo $xml->movie[0]->title;

echo '<br>'

$arr = $xml->movie[0]->characters[0]->character;

echo '<br>'

foreach($arr as $kk => $vv)

{

    echo $vv->name;

       echo '<br/>'

} 

?> 

结果为：

 $xml->movie[0]->title：

       PHP: Behind the Parser

 $vv->name： Ms. Coder

                       Mr. Coder 

这里是简单的方法，当然获取xml中节点值，还有很多方法 如：SimpleXML functions 等等
