Walkthrough

The updates modify how page titles are extracted from HTML and enhance XML entity encoding in the blog RSS feed. The first change switches from using innerHTML to textContent for title extraction. The second ensures that blog title and description fields are properly XML-encoded in the generated RSS feed.

Changes

File(s)	Change Summary
src/lib/build_index.ts	Switched page title extraction from innerHTML to textContent for improved text retrieval.
src/routes/(marketing)/blog/rss.xml/+server.ts	Added XML entity encoding for blog title and description fields in RSS feed generation.

Poem

In the warren of code, a title’s new quest,
From innerHTML to textContent—now it’s the best!
RSS feeds sparkle, encoded just right,
Special characters hop safely through the night.
🐇✨
Another day’s work, neat and complete,
Bugs and oddities now face defeat!

🧹 Nitpick comments (2)

src/lib/build_index.ts (1)

39-41: Switch to textContent for robust title extraction.

Using textContent instead of innerHTML correctly strips out HTML tags and prevents markup from polluting your search index. Consider adding a .trim() to remove any incidental whitespace around the title.

src/routes/(marketing)/blog/rss.xml/+server.ts (1)

20-23: Escape blogInfo fields in RSS feed with encodeXML.

Applying encodeXML to <title> and <description> ensures special characters are properly escaped in the XML output. Nice work! Optionally, you could migrate this manual string‐concatenation into a small XML-builder utility to improve maintainability.
