我希望像这样的标签格式显示xml

Answer 1

从你输出我假设你想要这样的东西：

<?php
    if (isset($_GET["filter"]))
    {
        $filter = $_GET["filter"];
        // create doctype
        $dom = new DOMDocument("1.0");

        switch($filter)
        {
            case "city":
                // display document in browser as plain text 
                // for readability purposes
                header("Content-Type: text/plain");

                // create root element
                $root = $dom->createElement("cities");
                $dom->appendChild($root);

                // create child element
                $item = $dom->createElement("city1");
                $root->appendChild($item);

                $item = $dom->createElement("city2");
                $root->appendChild($item);
            break;

            default:
                // do something else
        }
        // save and display tree
        echo $dom->saveXML();
    }
?>

请注意，您无法将XML元素的名称与空格分开，就像您在示例中所做的那样。

以下是示例php代码，运行此代码并将您的链接作为过滤器作为您的条件

    Header("Content-type: text/xml"); 
    // get query string params
    $filter = $_GET['filter'];

    $xml = '';

    If ($filter == "city"){
        $xml = $xml . '<continent name="city">';
        $xml = $xml . '<city id="1">Navi Mumbai</city>';
        $xml = $xml . '<city id="2">Thane</city>';
        $xml = $xml . '<city id="3">Pune</city>';
        $xml = $xml . '</continent>';
    }else If ($filter == "country"){
        $xml = $xml . '<continent name="country">';
        $xml = $xml . '<country id="100">India</country>';
        $xml = $xml . '</continent>';
    }else If ($filter == "state"){
        $xml = $xml . '<continent name="state">';
        $xml = $xml . '<state id="300">Maharastra</state>';
        $xml = $xml . '</continent>';
    }else{
        $xml = $xml . '<continent name="none">';
        $xml = $xml . '<country id="0">no result found</country>';
        $xml = $xml . '</continent>';
    }

    // send xml to client
    echo( $xml );
?>
