问题描述
我有一个从SOAP调用返回的一个长字符串到一个变量，我需要找到其中的某些元素的内容，即 .MoreInfoZone .OfferZone #Heading .content 和 .MoreInfoZone.OfferZone #Description .content 。
I have the following long string returned from a SOAP call into a variable, and I need to find the contents of certain elements within it, namely the .MoreInfoZone .OfferZone #Heading .content and .MoreInfoZone .OfferZone #Description .content.
我无法使用javascript ，因为它用于填充Facebook Open Graph的元标记，并且其蜘蛛程序不会运行javascript。
I can't do it with javascript, as it is for populating metatags for Facebook Open Graph, and their spiders won't run the javascript.
$soap = '

推荐答案
请考虑：
http://code.google.com/p/phpquery/
或
http://php.net/manual/en/class.domxpath.php
一个XPath示例可以be：
An XPath example could be:
<?php
$dom = new DOMDocument();
$dom->loadXml($soap);
$xpath = new DOMXPath($dom);
// .MoreInfoZone .OfferZone #Heading .content
$headingContent = $xpath->query('//*[@id="Heading"]//*[contains(@class, "Content")]')->item(0);
if ($headingContent instanceof DOMNode) {
echo $headingContent->nodeValue;
}
// .MoreInfoZone .OfferZone #Description .content
$descriptionContent = $xpath->query('//*[@id="Description"]//*[contains(@class, "Content")]/p')->item(0);
if ($descriptionContent instanceof DOMNode) {
echo $descriptionContent->nodeValue;
}
因为我通常只用xpath做这样的东西，我不能提供一个phpquery的工作示例。对不起，
as I normally only do stuff like this with xpath, I can't provide a working example with phpquery. Sorry about that.
