⚡ Optimize nested find in XML parsing

[Tcode-Motion]

• 💡 What: Optimized XML parsing by caching the position of the first > character instead of re-evaluating .find('>') multiple times.
• 🎯 Why: Re-evaluating .find('>') on a potentially large string adds unnecessary CPU overhead.
• 📊 Measured Improvement: Baseline was 6.541s for 100,000 iterations. After the optimization, it improved to 5.003s.
