如何从 php 中的 pre 标签解析 XML？

Question

I am getting a response from curl something like this

<pre>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
\t&lt;ksiazka kod=&quot;WKSPA4&quot; id=&quot;1168&quot;&gt;
\t\t&lt;dzien data=&quot;2020-12-22&quot;&gt;1&lt;/dzien&gt;
\t&lt;/ksiazka&gt;

How can I parse it and read as normal XML in php?

My code looks like:

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
print_r($response)

You can do some basic string manipulation to remove the junk and then load into DOMDocument,

$str='<pre>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
    \t&lt;ksiazka kod=&quot;WKSPA4&quot; id=&quot;1168&quot;&gt;
    \t\t&lt;dzien data=&quot;2020-12-22&quot;&gt;30&lt;/dzien&gt;
    \t&lt;/ksiazka&gt;';
    
$xml=str_replace( array('\t','<pre>'), '', html_entity_decode($str) );
$dom=new DOMDocument;
$dom->loadXML( $xml );
/* do other fudgery here if desired... */
printf('<textarea cols=80 rows=10>%s</textarea>',$dom->saveXML());

Which yields:

I personally like Symfony DomCrawler Component Component to do such jobs
