Question

http://www.topbuy.com.au/tbcart/tbadmin/datafeed/shoppingcom.xml

这是我的Feed网址，它永远不会在浏览器中打开，也不需要花费数小时才能打开它。

我想创建PHP页面，我想在我的PHP页面中放置一个搜索框（我将放置），一旦点击提交我的PHP代码，应搜索并显示相应的产品PRICE。

那么我应该使用SimpleXML来提供这个或任何其他建议吗？

我建议使用XMLReader类，因为它不需要立即将完整的xml加载到内存中。

缺点是您必须手动实现搜索和过滤，对于简单的名称搜索，您可以执行以下操作：

$reader = new XMLReader;
$reader->open('shoppingcom.xml');

while ($reader->read()) {
    if ($reader->name == 'Product') {
        $productxml = $reader->readOuterXML();
        while ($reader->read()) {
            if ($reader->name == 'ProductName' && stristr($reader->readInnerXML(), 'adidas')) {
                print $productxml;
                // now it contains the <Product>...</Product> fragment of the xml
                // you can use simplexml on this fragment, or just add an if for Prize node
            }
            if ($reader->name == 'Product' && $reader->nodeType == XMLReader::END_ELEMENT) {
                break;
            }
        }
    }
}

尽管如此，示例Feed仍为实心64M，如果您为此创建一个可以索引要搜索的字段并返回xml片段的数据库，则可能会有更好的实时搜索结果，所以您不要不必将所有内容规范化为表格。

使用PHP在非常大的XML FEED中搜索数据
