PHP Convert Mysql 获取的xml数据

Question

假设我从 mysql 表中获取此数据并将其存储在变量 $xmlFromMysqlRow

<?xml version="1.0" encoding="utf-8"?>
<GridInstantMessage xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</GridInstantMessage>

我如何将此 xml 的每个部分存储到它们自己的变量中？例如，我希望所有内容都存储在

<message>
</message>

要存储在 $message 中，我该怎么做？

使用适当的 XML 解析器可靠且轻松地提取 XML 文档的任何部分。这是一个使用 SimpleXML 的例子:

$string = <<<XML
<GridInstantMessage xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <fromAgentID>d8445b4a-4ed0-4449-bf33-7709443f7f84</fromAgentID>
   <fromAgentName>FABIODK TOPAZ</fromAgentName>
   <toAgentID>70d0f6b8-237d-4863-9aef-96e2c93d5130</toAgentID>
   <dialog>32</dialog>
   <fromGroup>true</fromGroup>

   <binaryBucket>AADYRFtKTtBESb8zdwlEP3+EAA==</binaryBucket>
   <ParentEstateID>0</ParentEstateID>
   <RegionID>00000000-0000-0000-0000-000000000000</RegionID>
   <timestamp>1437412707</timestamp>
</GridInstantMessage>
XML;
$xml = new SimpleXMLElement($string);
$message = $xml->xpath("//message")[0]->asXML();
echo $message;

eval.in demo

输出:

<message>festa|SPLODERS E PREMIOS PRAS 3  MELHORES ROUPAS, O SPLODER MAIOR VAI ESTAR COM 500 AV$ FIXOS AT� O FIM DA FESTA.
      A PARTIR DAS 20:00 HORAS.
