Describe the bug

I'm trying to add the URL https://www.trendmicro.com/en_us/research.html?category=trend-micro-research:article-type/research to FreshRSS. It does not have a RSS feed available, so I'm using HTML + XPath to create one. However, after setting it up, it returns "This feed is empty. Please verify that it is still maintained."

FreshRSS[101]: FreshRSS uses cache for https://www.trendmicro.com/en_us/research.html?category=trend-micro-research:article-type/research
[Sun Feb 09 17:57:45.862013 2025] [php:notice] [pid 101:tid 101] [client 100.75.65.61:51717] PHP Notice:  is invalid XML, likely due to invalid characters. XML error: XML_ERR_NAME_REQUIRED at line 32, column 39 in /var/www/FreshRSS/lib/simplepie/simplepie/src/SimplePie.php on line 1917

To Reproduce

1. Add the feed with source type HTML + XPath
2. Update the feed
3. See error

Expected behavior

To work as normal

FreshRSS version

1.25.0
