我正在尝试使用 XMLReader class 解析此文件并将其保存到数据库中。我如下解析了所有的 noteType。

    $xmlReader = new XMLReader();
        $xmlReader->open('http://.........');
        while ($xmlReader->read()) {

            if ($xmlReader->nodeType == XMLReader::ELEMENT && $xmlReader->localname == "item") {
                $xmlReader->read();
                $item = array();

            }
            
            if ($xmlReader->nodeType == XMLReader::ELEMENT && $xmlReader->prefix == "g") {

                if ($xmlReader->localName == 'id') {
                    $xmlReader->read();
                    $item['g:id'] = $xmlReader->value;
                }
                if ($xmlReader->localName == 'title') {

我无法解析。我如何解析这里的结并将其转移到循环中。我尝试了很多东西。但是我得合理使用XMLReaderClass。解析后，我将其注册到数据库中。存入数据库没有问题。问题是我无法解析具有与上述相同标签的图像路径。

我该怎么做？你能帮帮我吗

Answer 1

您可以通过将每个 <item> 节点导入 SimpleXMLElement 来简化 XMLReader 中的大量样板代码。这样可以更轻松地一次处理每个完整元素。

在此代码中，每个 <item> 使用一个 foreach() 循环将所有子元素提取到一个单独的数组（$item 数组）中。如果已经遇到该项目，则将其转换为项目数组，并将后续的每个项目添加到列表中...

$xmlReader = new XMLReader();
$xmlReader->open('http://.........');
$doc = new DOMDocument('1.0','UTF-8');
while ($xmlReader->read()) {
    
    if ($xmlReader->nodeType == XMLReader::ELEMENT && $xmlReader->localName == "item") {
        // Load the XML under the <item> tag into SimpleXML
        $data = simplexml_import_dom($doc->importNode($xmlReader->expand(), true));
        $item = [];
        // Loop over the child elements from the 'g' namespace
        foreach  ($data->children("g", true) as $tag => $value )    {
            $tag = "g:".$tag;
            // If an item with that tag name already exists, convert it to an array of items
            if ( isset($item[$tag]) )   {
                if ( !is_array($item[$tag]))    {
                    $item[$tag] = [$item[$tag]];
                }
                $item[$tag][] = (string)$value;
            }
            else    {
                // For normal items, add in the value (as a string) to the array
                $item[$tag] = (string) $value;
            }
        }
        // Store new item
        $items[] = $item;
    }
}

所以你的数组将包含类似...

Array

    [g:additional_image_link] => Array
        (

您必须决定如何处理这些项目，但这将为您提取数据。
