Question

我想创建基于数据库记录的xml doc我已编码这些行，但我不知道如何将父节点放入其中：

$dom = new DOMDocument("1.0");
//header("Content-Type: text/plain");

while ($row = mysql_fetch_row($dtrs)) {
    //create sub toping..

    $root = $dom->createElement("case");
    $dom->appendChild($root);

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

    // create text node
    $caseno_text = $dom->createTextNode($row[0]);
    $caseno->appendChild($caseno_text);


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

    // create text node
    $pet_text = $dom->createTextNode($row[1]);
    $petname->appendChild($pet_text);

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

    // create text node
    $res_text = $dom->createTextNode($row[2]);
    $resname->appendChild($res_text);

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

    // create text node
    $hear_text = $dom->createTextNode($row[3]);
    $hearing->appendChild($hear_text);


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

    // create text node
    $status_text = $dom->createTextNode($row[4]);
    $status->appendChild($status_text);
}

我得到这样的结果，我无法将节点放入其中

<?xml version="1.0"?> <case> <caseno>010301</caseno> <petname>ashiq</petname> <resname>state</resname> <hearing>8012-08-02</hearing> <status>P</status> </case> <caseno>010302</caseno> <petname>hussain</petname> <resname>state</resname> <hearing>8012-08-02</hearing> <status>P</status> </case>

实际上我想要这样的结果;

<?xml version="1.0"?> <stage> <case> <caseno>010301</caseno> <petname>ashiq</petname> <resname>state</resname> <hearing>8012-08-02</hearing> <status>P</status> </case> <caseno>010302</caseno> <petname>hussain</petname> <resname>state</resname> <hearing>8012-08-02</hearing> <status>P</status> </case> </stage>

请帮帮我。

您不能拥有多个根元素。您需要在循环外部分配一个根元素，并向其追加case个元素：

<?xml version="1.0"?>
<cases>
    <case>
        <caseno>010301</caseno>
        <petname>ashiq</petname>
        <resname>state</resname>
        <hearing>8012-08-02</hearing>
        <status>P</status>
    </case>
    <case>
        <caseno>010302</caseno>
        <petname>hussain</petname>
        <resname>state</resname>
        <hearing>8012-08-02
        </hearing>
        <status>P</status>
    </case>
</cases>

另外，作为旁白：

Please, don't use mysql_* functions in new code。它们不再被维护，deprecation process已经开始了。请参阅red box？转而了解prepared statements，并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。

使用php从mysql数据库创建xml doc
