问题描述
在php中我想打开一个html文件，删除div（class Areas）的内容并保存。
$ dom = new DOMDocument;
$ dom-> loadHTMLFile（temp / page。$ y。。xhtml）;
$ xpath = new DOMXPath（$ dom）;
$ pDivs = $ xpath-> query（.// div [@ class ='Areas']）;
foreach（$ pDivs as $ div）{
$ div-> parentNode-> removeChild（$ div）;
}
echo htmlspecialchars（$ dom-> saveHTMLFile（））;
不起作用...
< html>
< head>
< title>< / title>
< link href =css.css =stylesheettype =text / css/>
< / head>
< body>
< div style =height：998px;>
< img src =images / bg004.jpg/>
< div class =class1>
< div class =class2>< / div>
< div class =class2>< / div>
< / div>
< div class =Areas>
< div class =Area>< a href =index.html>< / a>< / div>
< div class =Area>< a href =index.html>< / a>< / div>
< div class =Area>< a href =index.html>< / a>< / div>
< / div>
< / div>
< / body>
< / html>
我想得到这样的结果：
< HTML>
< head>
< title>< / title>
< link href =css.css =stylesheettype =text / css/>
< / head>
< body>
< div style =height：998px;>
< img src =images / bg004.jpg/>
< div class =class1>
< div class =class2>< / div>
< div class =class2>< / div>
< / div>
< div class =Areas>
< / div>
< / div>
< / body>
< / html>

如何做同样的事情，但我的文件现在是一个XML？
我测试了这个：
copy（temp / page。$ y。。xhtml，/ temp / page 。$ Y XML）。
$ dom = new DOMDocument;
$ dom-> load（temp / page。$ y。。xml）;
$ xpath = new DOMXPath（$ dom）;
$ pDivs = $ xpath-> query（.// div [@ class ='Area']）;
foreach（$ pDivs as $ div）{
$ div-> parentNode-> removeChild（$ div）;
}
$ dom-> savexml（）;
现在我已经
<？xml version =1.0encoding =utf-8？>
< html>
< head>
< title>< / title>
< link href =css.css =stylesheettype =text / css/>
< / head>
< body>
< div style =height：998px;>
< img src =images / bg004.jpg/>
< div class =class1>
< div class =class2>< / div>
< div class =class2>< / div>
< / div>
< div class =Areas>
< div class =Area>< a href =index.html>< / a>< / div>
< div class =Area>< a href =index.html>< / a>< / div>
< div class =Area>< a href =index.html>< / a>< / div>
< / div>
< / div>
< / body>
< / html>
解决方案
您几乎就在那里。您只需将 Areas 更改为 Area ，然后使用 saveHtmlFile 而不是 saveHTML ：
$ dom = new DOMDocument;
$ dom-> loadHTMLFile（temp / page。$ y。。xhtml）;
$ xpath = new DOMXPath（$ dom）;
$ pDivs = $ xpath-> query（.// div [@ class ='Area']）;
foreach（$ pDivs as $ div）{
$ div-> parentNode-> removeChild（$ div）;
}
$ dom-> saveHTMLFile（temp / page。$ y。。xhtml）;
假设您想要将HTML保存回原始文档。请注意，DOMXPath将在文档的顶部添加文档类型，我认为没关系？
in php I would like to open a html file, delete the content of the div(class Areas) and save it.
$dom = new DOMDocument;
$dom->loadHTMLFile( "temp/page".$y.".xhtml" );
$xpath = new DOMXPath( $dom );
$pDivs = $xpath->query(".//div[@class='Areas']");
foreach ( $pDivs as $div ) {
$div->parentNode->removeChild( $div );
}
echo htmlspecialchars($dom->saveHTMLFile());
It doesn't work...
My html file look :
<html>
<head>
<title></title>
<link href="css.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div style="height:998px;">
<img src="images/bg004.jpg" />
<div class="class1">
<div class="class2"></div>
<div class="class2"></div>
</div>
<div class="Areas">
<div class="Area"><a href="index.html"></a></div>
<div class="Area"><a href="index.html"></a></div>
<div class="Area"><a href="index.html"></a></div>
</div>
</div>
</body>
</html>
I would like to have this result :
<html>
<head>
<title></title>
<link href="css.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div style="height:998px;">
<img src="images/bg004.jpg" />
<div class="class1">
<div class="class2"></div>
<div class="class2"></div>
</div>
<div class="Areas">
</div>
</div>
</body>
</html>
Thank for your help
UPDATE
How to do the same thing but my file is now a xml ?
I test this :
copy("temp/page".$y.".xhtml", "/temp/page".$y.".xml");
$dom = new DOMDocument;
$dom->load( "temp/page".$y.".xml" );
$xpath = new DOMXPath( $dom );
$pDivs = $xpath->query(".//div[@class='Area']");
foreach ( $pDivs as $div ) {
$div->parentNode->removeChild( $div );
}
$dom->savexml();
And I have now
<?xml version="1.0" encoding="utf-8"?>
<html>
<head>
<title></title>
<link href="css.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div style="height:998px;">
<img src="images/bg004.jpg" />
<div class="class1">
<div class="class2"></div>
<div class="class2"></div>
</div>
<div class="Areas">
<div class="Area"><a href="index.html"></a></div>
<div class="Area"><a href="index.html"></a></div>
<div class="Area"><a href="index.html"></a></div>
</div>
</div>
</body>
</html>
解决方案
You were very nearly there. You just needed to change Areas to Area and then use saveHtmlFile instead of saveHTML:
$dom = new DOMDocument;
$dom->loadHTMLFile( "temp/page".$y.".xhtml" );
$xpath = new DOMXPath( $dom );
$pDivs = $xpath->query(".//div[@class='Area']");
foreach ( $pDivs as $div ) {
$div->parentNode->removeChild( $div );
}
$dom->saveHTMLFile("temp/page".$y.".xhtml");
This is assuming you want to save the HTML back to the original document. Do note that DOMXPath will add a doctype to the top of your document, I assume that's okay?
