问题描述
< html xmlns =http：//www.w3 .ORG / 1999 / XHTML>
< head>
< meta http-equiv =Content-Typecontent =text / html; charset = utf-8>
< link rel =stylesheettype =text / csshref =css / style.css>
< link rel =stylesheettype =text / csshref =css / elements.css>
< title>页面< / title>
<！ - [if lte IE 6]>
< link rel =stylesheettype =text / csshref =css / ie6.css/>
<！[endif] - >
< / head>
etc ...
我正在使用DomDocument库来修改< link> 属性。有没有办法让DomDocument读取和修改条件注释中的< link> 元素。
解决方案
foreach（$ dom-> getElementsByTagName（'head'）as $ head）{
foreach（$ head-> childNodes as $ node）{
if（$ node instanceof DOMComment）{
$ node-> replaceData（16,60，'test'）;
}
}
}
此代码工作，我只是让您搜索如何获取replaceData方法的'offset'和'count'值！
I have this html file with a conditional comment.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="css/style.css">
<link rel="stylesheet" type="text/css" href="css/elements.css">
<title>Page</title>
<!--[if lte IE 6]>
<link rel="stylesheet" type="text/css" href="css/ie6.css" />
<![endif]-->
</head>
etc...
I am using the DomDocument library to modify the <link> attributes. Is there any way of getting DomDocument to read and modify the <link> element in the conditional comments.
解决方案
foreach($dom->getElementsByTagName('head') as $head) {
foreach($head->childNodes as $node) {
if($node instanceof DOMComment) {
$node->replaceData(16,60,'test');
}
}
}
This code works, I just let you search how to get 'offset' and 'count' value for the replaceData method !
