我的网关在购买时向我的服务器发送(发布)xml datafeed。 XML看起来像这样:

 <?xml version='1.0' standalone='yes'?>

XML;

作为第一次进行XML解析体验,我希望有人能告诉我如何进行并将其转换为php数组或类似的东西,以便我可以将我想要的数据插入到mysql表中。

最简单的方法是什么?

5 个答案:

答案 0 :(得分:6)

您可以使用PHP XML解析器,例如SimpleXML

答案 1 :(得分:3)

您可以将以下代码段与xml_parse_into_struct一起使用,将您的XML分成两个PHP数组,一个包含数据,另一个包含指向values数组中显示的标记的位置:

$parser = xml_parser_create();

$values = array();
$index = array();

xml_parse_into_struct  ($parser, $xml, &$values, &$index);

var_dump($values);
var_dump($index)

$ xml包含XML数据。查看我链接到的手册页中的示例以获取更多信息。

答案 2 :(得分:2)

您可以使用builtin XML parser,手册应该为您提供所需的一切。但是从经验来讲,我真的建议学习Xpath,因为它很多更快,更容易使用,然后你可以通过PHP得到任何其他东西。您可以从introduction@w3schools开始,查看nice examples in the specs并最终使用PHP functions

用于选择交易ID的示例查询将是

$document = new DOMDocument();
$document->load('YourFile.xml');
$xpath = new DOMXPath($document);

# Query id
$ids = $xpath->query('/transactions/transaction/id/text()');
# $ids is a DOMNodeList object
assert($ids->length === 1);
$id = $ids->item(0);

# Query date
$dates = $xpath->query('/transactions/transaction/transaction_date/text()');
# $dates is a DOMNodeList object
assert($dates->length === 1);
$id = $dates->item(0);

答案 3 :(得分:1)

最好是使用PHP XML Parser。 IMO,最好是使用PHP DOM,因为在每种语言(或左右)中,您都可以使用相同的方法找到这个库。

答案 4 :(得分:0)

解析XML:
如果您的服务器只接收XML(不在$ _POST ['xmlfeed']中):

$xml = file_get_contents("php://input");  
$data = simplexml_load_string ($xml);  

不要将SimpleXML对象转换为数组。无论如何,它的工作方式非常类似于数组。您可以使用foreach,并且可以轻松访问其元素 http://us2.php.net/manual/en/simplexml.examples-basic.php

P.S。对于大型XML文档,请使用XMLReader()而不是SimpleXML。
