How to replace the content of my xml file in php? - php

Question

I know to translate the content of my XML file. For that I extract the code with the function file_get_contents and I convert it into text with the library Html2Text. I have translated the content of the file, but when I get to the end to replace the content with two arrays using the str_replace function, it does not work too well. There is a part that is translated and another that is not.
Here is my code
// We will return our text in an array.
$explodesTextForTranslatingArr = array_filter( explode(WEBSITE_NAME, $textForTranslating), 'strlen' );
$explodesTextForTranslatingArr = array_map('trim', $explodesTextForTranslatingArr);
$countExplodestextForTranslating = count($explodesTextForTranslatingArr);
// We will return our text that we have translated into an array.
$explodesTextAddForTranslatingArr = array_filter( explode(WEBSITE_NAME, $textTranslating), 'strlen' );
$explodesTextAddForTranslatingArr = array_map('trim', $explodesTextAddForTranslatingArr);
$countExplodesTextAddForTranslating = count($explodesTextAddForTranslatingArr);
$textForTranslatingArr = [];
foreach ($explodesTextForTranslatingArr as $value) {
if (!empty($value)) {
$textForTranslatingArr[] = $value;
}
}
$textAddForTranslatingArr = [];
foreach ($explodesTextAddForTranslatingArr as $value) {
if (!empty($value)) {
$textAddForTranslatingArr[] = $value;
}
}
$updateAllContentFromXml = str_replace($textForTranslatingArr, $textAddForTranslatingArr, $fileGetContentFileXml);
echo '<pre>';
print_r($fileGetContentFileXml);
Here is a snippet of the result of my XML file:

EDIT:
Here are some essential explanations on the use of its three variables.
The variable $textForTranslatingArr store the text for translation in the array by filtering the data to remove the site name in the text.
The variable $textAddForTranslatingArr will add the translated text into a new array. By filtering the data i.e. by removing the name of the site and the spaces that we had in the previous text.
The variable $fileGetContentFileXml will display the content of our XML file and this content will be replaced by our translated content. This content is stored in the variable $textAddForTranslatingArr. Now I explain you the functionality of these three variables, what should I do so that I can solve this bug please?
I don't know why all the content is not translated exactly as it is in the array. Can you give me an idea or show me where I made the mistake in my code please?
