DomDocument和html实体 [英] DomDocument and html entities

问题描述

我正在尝试解析包含一些HTML实体的HTML，例如

I'm trying to parse some HTML that includes some HTML entities, like ×

$str = '<a href="http://example.com/"> A &#215; B</a>';

$dom = new DomDocument;
$dom -> substituteEntities = false;
$dom ->loadHTML($str);

$link = $dom ->getElementsByTagName('a') -> item(0);
$fullname = $link -> nodeValue;
$href = $link -> getAttribute('href');

echo "
fullname: $fullname \n
href: $href\n";    

但是DomDocument用A？B代替文本。

but DomDocument substitutes the text for for A × B.

有没有办法让它不接受&对于一个html实体，让它只是离开它？我试图将substituteEntities设置为false，但它不做任何事情

Is there some way to keep it from taking the & for an html entity and make it just leave it alone? I tried to set substituteEntities to false but it doesn't do anything

推荐答案

从文档：

DOM扩展使用UTF-8编码。

使用utf8_encode（）和utf8_decode（）处理ISO-8859-1编码中的文本或Iconv for other编码。

The DOM extension uses UTF-8 encoding.
Use utf8_encode() and utf8_decode() to work with texts in ISO-8859-1 encoding or Iconv for other encodings.

假设您使用的是latin-1，请尝试：

Assuming you're using latin-1 try:

<?php
header('Content-type:text/html;charset=iso-8859-1');


$str = utf8_encode('<a href="http://example.com/"> A &#215; B</a>');

$dom = new DOMDocument;


$dom -> substituteEntities = false;
$dom ->loadHTML($str);

$link = $dom ->getElementsByTagName('a') -> item(0);
$fullname = utf8_decode($link -> nodeValue);
$href = $link -> getAttribute('href');

echo "
fullname: $fullname \n
href: $href\n";    ?>
