Fix metadata parsing for large numbers in XML responses

Description

Fixed an issue with metadata parsing where large numbers in XML responses were being incorrectly handled due to BigInt conversion. Updated XMLParser configuration to properly handle leading zeros and maintain string representation of large numbers.

Changes

• Added numberParseOptions to XMLParser configuration
• Set leadingZeros: true to preserve leading zeros in numeric strings
• Set eNotation: false to prevent scientific notation conversion
• Set hex: true to properly handle hexadecimal values

Problem

Previously, large numbers in metadata could be incorrectly parsed or lose precision when converted to JavaScript numbers, especially when dealing with BigInt values.

Solution

Updated XMLParser initialization with proper number parsing options to maintain string representation of numeric values and preserve leading zeros.

Testing

• Tested with large number metadata values
• Verified leading zeros are preserved
• Confirmed BigInt values are correctly handled
