What is wrong with xml file?

Question

XML

Why does the browser swear? I tried to change the quotes and it seems that the tags are all closed ...

<?xml version="1.0" encoding="windows-1251"?>
<!DOCTYPE yml_catalog SYSTEM "shops.dtd">
<yml_catalog date="2018-01-30 17:40">
<shop>
<name>Магазин</name>
<company>Nest</company>
<url>http://www.test.ru</url>
<version>Выгрузка для сайта test.net</version>
<category id='124'>Основной раздел каталога</category>
<offers>
<offer>

Parse error: syntax error, unexpected 'version'
(T_STRING) in /home/bitrix/www/yandex/new.php on line 1

Answer 1

Because the file extension is .php and <? assumes the beginning of the php code. Change the file extension to xml.
Or replace the first line with

<?php echo '<?xml version="1.0" encoding="windows-1251"?>' ?>
