我无法解析这个 xml...真正的 xml 是 here

    <?xml version="1.0" encoding="ISO-8859-1" ?>
<eqlist>
    <earhquake  name="2012.12.31 18:35:13"  lokasyon="CAMONU-AKHISAR (MANİSA)                           İlksel" lat="38.9572"   lng="27.8965"   mag="2.9" Depth="5.0" />
    <earhquake  name="2012.12.31 18:54:09"  lokasyon="VAN GÖLÜ                                          İlksel" lat="38.7273"   lng="43.1598"   mag="2.3" Depth="2.1" />
    <earhquake  name="2012.12.31 21:00:49"  lokasyon="KUCUKESENCE-ERENLER (SAKARYA)                     İlksel" lat="40.7347"   lng="30.4742"   mag="1.9" Depth="4.4" />
</eqlist>

我该如何解析它？问题来自运行不错的远程站点的谷歌地图应用程序的 xml 文件的前两个字符。看看那个数组

[0] => ÿþ<?xml version="1.0" encoding="ISO-8859-1" ?>

Answer 1

您可以使用 SimpleXML_Load_String。

<?php // RAY_temp_burhan.php
error_reporting(E_ALL);
echo '<pre>';

$xml = <<<ENDXML
<?xml version="1.0" encoding="ISO-8859-1" ?>
<eqlist>
    <earhquake  name="2012.12.31 18:35:13"  lokasyon="CAMONU-AKHISAR (MANISA)                           Ilksel" lat="38.9572"   lng="27.8965"   mag="2.9" Depth="5.0" />
    <earhquake  name="2012.12.31 18:54:09"  lokasyon="VAN GÖLÜ                                          Ilksel" lat="38.7273"   lng="43.1598"   mag="2.3" Depth="2.1" />
    <earhquake  name="2012.12.31 21:00:49"  lokasyon="KUCUKESENCE-ERENLER (SAKARYA)                     Ilksel" lat="40.7347"   lng="30.4742"   mag="1.9" Depth="4.4" />
</eqlist>
ENDXML;

// CONVERT TO AN OBJECT
$obj = SimpleXML_Load_String($xml);

// PARSE OUT SOME ATTRIBUTES
foreach ($obj as $quake)
{
    // ATTRIBUTE NAMES ARE CASE-SENSITIVE
    $loc = $quake->attributes()->lokasyon;
    $dep = $quake->attributes()->Depth;
    echo PHP_EOL . "$loc $dep";
}

Answer 2

面向对象的方式

$xml = <<<ENDXML
<?xml version="1.0" encoding="ISO-8859-1" ?>
<eqlist>
    <earhquake  name="2012.12.31 18:35:13" 
                lokasyon="CAMONU-AKHISAR (MANISA) Ilksel"
                lat="38.9572"
                lng="27.8965"   mag="2.9" Depth="5.0" />
    <!-- Etc... -->
</eqlist>
ENDXML;

$dom = new DOMDocument();
$dom->loadXML($xml, LIBXML_NOBLANKS);

然后就可以使用DOMDocument定义的各种方法了。其中一种用于检查 XSD 有效性的方法是 schemaValidate
