当我在PHP文件中使用DOMDocument时,出现以下错误:

  

警告:DOMDocument :: loadXML()[domdocument.loadxml]:实体中标记节点第7行中数据的过早结束,第7行中D:\ wamp \ www \ dom1.php中第7行:

php代码如下:

<?php

您需要关闭elements,例如</node></field>

<nodes>
    <node>text<node>
<node>
    <field>hello<field>
    <field>world<field>
<node>
<nodes>

更改为:

<nodes>
    <node>text</node>
<node>
    <field>hello</field>
    <field>world</field>
</node>
</nodes>

答案 1 :(得分:1)

将您的XML更改为:

$sXml = <<<XML
<nodes>
    <node>text</node>
    <node>
        <field>hello</field>
        <field>world</field>
    </node>
</nodes>
XML;

注意对<nodes></nodes><node></node><field></field>。您必须将每个已打开的标记与其已关闭的标记进行匹配。 See w3Schools for more about XML
