PHP XML Parser - 忽略嵌套/子标签 [英] PHP XML Parser - ignoring nested/child tags

问题描述

我遇到过使用 XML 解析器从 php://input 中提取数据的情况.

I've got a situation where I'm using an XML parser to extract data from a php://input.

正在发送的数据看起来像:

The data being sent in looks like:

<this>foo</this>
<that>bar></that>
<data><dong>zebras</dong><fong>monkeys</fong></data>

现在，问题是因为处理程序:

Now, the issue is that because the handler:

$xml_parser = xml_parser_create();

xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($xml_parser, "startTag", "endTag");
xml_set_character_data_handler($xml_parser, "contents");

$document = file_get_contents("php://input");                  

xml_parse($xml_parser, $document);

xml_parser_free($xml_parser);

...正在为我解释标签以破译内容以使其有用...它似乎缺少 <data> 中的任何内容，即我需要找出如何获得它忽略子元素/嵌套元素/标签，只是将数据排除在外.

...is interpreting tags for me to decipher the contents to make it useful... It seems to be missing anything within <data> i.e. I need to find out how i can get it to ignore the child/nested elements/tags and just bosh out the data whatever.

推荐答案

WideDonkey，您考虑过使用 DOM 吗?你可以轻松做到:

WideDonkey, have you considered using the DOM instead? You can easily do :

$dom = new DOMDocument();
$dom->loadXML(file_get_contents('php://input'));

$data = $dom->getElementsByTagName('data');
$data = $data[0]->asXML();
