实际数据，更新3。实际数据，实际数据，

<?xml version="1.0" encoding="UTF-8"?>    
<properties>
 <property>
 <location>
 <street-address>xyz</street-address> 
   <city-name>zyx</city-name>
 </location>
 <details>
 <price>111111</price>
 <description>xyz</description>
</details></property>

<property>
 <location>
 <street-address>xyz</street-address> 
   <city-name>zyx</city- name>
 </location>
 <details>
 <price>111111</price>
 <description>xyz</description>
</details></property>

我有这个xml数据，现在我想在“描述”中搜索一些像“GOOD”这样的关键词然后如何用PHP搜索它？

<?php

 foreach ($xml->property as $property)
{

   //echo $property->details->description;

   if ($property->details->description == 'good')
      {
        echo "SUCCESFuL";
      }
  echo "NON SUCCESFUL";
 }
?>

你可以使用XPath，虽然我假设有一个属性列表（我刚刚为源XML添加了另一个级别）。

$data = <<< XML
<List>
<property><location>USA</location>
  <detail>
    <state>NY</state>
    <city>new york</city>

    <description> NY is good city </description>

  </detail>
</property>
</List>
XML;

$xml = simplexml_load_string($data);
$goodProperty = $xml->xpath("//property[detail/description[contains(translate(.,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghihklmnopqrstuvwxyz'),'good')]]");
foreach ( $goodProperty as $property )  {
    echo $property->location."-".$property->detail->description.PHP_EOL;
}

这节省了必须循环遍历每个条目，因为XPath为您执行此操作并仅返回具有“好”的属性。在描述中。 XPath中的尴尬部分是确保它不区分大小写，这就是translate的作用。

此输出（对于样本）......

USA- NY is good city

<强>更新

或者是否存在简单检查......

$xml = simplexml_load_string($data);
foreach ( $xml->property as $property ) {
    if ( stripos($property->detail->description, "good") !== false ){
        echo "Success";
    }
    else    {
        echo "Non Success";
    }
}

stripos执行不区分大小写的搜索，如果找不到则返回false。

更新2a：

$filename ="data.xml";
$xml = simplexml_load_file($filename);
if ( stripos($xml->detail->description, "good") !== false ){
    echo "Success";
}
else    {
    echo "Non Success";
}

data.xml包含...

<?xml version="1.0" encoding="utf-8"?>
<property>
    <location>
        <street-address>xyz</street-address>
        <city-name>zyx</city-name>
    </location>

    <detail>
        <price>699900</price>
        <description>xyz good</description>
    </detail>
</property>

更新3.1 ...

$xml = simplexml_load_file($filename);
foreach ( $xml->property as $property ) {
    if ( stripos($property->details->description, "good") !== false ){
        echo "Success";
    }
    else    {
        echo "Non Success";
    }
}
