如何使用PHP的str_replace移除文本及XML中的
字符

Ah, I see the issue here! When you're using DOMXPath to extract text content from XML/HTML, the entity 
 (which represents a carriage return, CR) gets automatically parsed into an actual carriage return character (\r) by the DOM parser. That's why your current str_replace("
", "", $desc) isn't working—there's no literal 
 string left in the nodeValue anymore; it's been converted to the raw character.

Correct Approach for DOM Parsed Content #

You need to target the actual carriage return character (\r) instead of the entity string. Here's how to adjust your code:

// Your existing code to retrieve the text node
$c = $xpath->query("div[@class = 'show']/text()", $container)->item(0);
$desc = $c->nodeValue;

// Replace the raw carriage return character (\r)
$desc = str_replace("\r", "", $desc);

echo $desc;

Bonus: Handling Raw XML Strings (Before Parsing) #

If you're working directly with the unparsed XML string (before feeding it into DOMXPath), you can still use the entity string in str_replace like this:

$rawXml = '<programme start="20180124160000 +0200" stop="20180124164500 +0200" channel="506"><title lang="he">&#13; ריזולי ואיילס 7 11. הגופה</title><desc lang="he">&#13; מתח. 11. הגופה: גופתו של קברן נמצאת בתוך ארון קבורה של אחד מלקוחותיו והדבר מוביל את חברי הצוות לחשיפת גופות נוספות. ג\'יין מבשרת לקרוביה על החלטתה לעבור לאף.בי.איי.</desc></programme>';

// Remove the &#13; entities directly from the raw string
$cleanXml = str_replace("&#13;", "", $rawXml);

// Now you can parse $cleanXml with DOMXPath if needed

Why This Works #

• When DOM parses the XML, it resolves character entities to their corresponding ASCII/Unicode characters. So 
 becomes \r (carriage return) in the node's text value.
• Targeting \r directly in str_replace ensures you're removing the actual character that's present in your $desc variable.
