当我在PHP中使用DOMDocument时,我会得到以下错误:
警告: DOMDocument::loadXML() domdocument.loadxml:实体中的第7行和第77行上的第7行:\wamp\www\dom1.php中的数据过早结束 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记节点第6行中的数据过早结束,第77行中为7行D:\wamp\www\dom1.php 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记字段中数据的过早结束,实体中的第5行,D中的第7行:\wamp\www\dom1.php,第77行 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记字段中数据的过早结束,实体中的第5行,D中的第7行:\wamp\www\dom1.php,第77行 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记字段中数据的过早结束,实体中的第4行,D中的第7行:\wamp\www\dom1.php,第77行 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记字段中数据的过早结束,实体中的第4行,D中的第7行:\wamp\www\dom1.php,第77行 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记节点第3行中的数据过早结束,第77行中为7行D:\wamp\www\dom1.php 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记节点第2行中的数据过早结束,第77行中为7行D:\wamp\www\dom1.php 警告: DOMDocument::loadXML() domdocument.loadxml:实体中标记节点第2行中的数据过早结束,第77行中为7行D:\wamp\www\dom1.php 警告: DOMDocument::loadXML() domdocument.loadxml:实体中的标记节点第1行,实体中的第7行:第77行数组(0)上的wamp\www\dom1.php
php代码如下所示:
<?php

}
}

}
}

}
$sXml = <<<XML

XML;
$dom = new MyDOMDocument;

var_dump($dom->toArray());

您需要关闭elements,例如</node>和</field>
<nodes>
<node>text<node>
<node>
<field>hello<field>
<field>world<field>
<node>
<nodes>改为:
<nodes>
<node>text</node>
<node>
<field>hello</field>
<field>world</field>
</node>
</nodes>发布于 2011-04-12 04:00:31
将XML更改为:
$sXml = <<<XML
<nodes>
<node>text</node>
<node>
<field>hello</field>
<field>world</field>
</node>
</nodes>
XML;注意这对<nodes></nodes>,<node></node>,<field></field>。你必须把每个打开的标签和它的封闭标签匹配起来。有关XML的更多信息,请参见w3Schools。。
