Describe the bug
On some areas of the screen following error is thrown:

Expected behavior
I expect service to ignore unrecognised characters while parsing the values

Also I'm getting: "2022-11-18 21:40:09 ERROR Error: An error happened when parsing the getSystemOcrData, see: Error: An error happened when parsing the getSystemOcrData, see: Error: Attribute without value
[0-0] Line: 110
[0-0] Column: 14
[0-0] Char: v"
error in some cases

Sorry for the late response, do you have a sample I can run?

[AndreiTsialenchanka]

@wswebcreation, sure

1. open this exact github page in the mobile browser (Screenshot attached),
2. run the command on iPhone 11 simulator: await driver.ocrGetText()

Error:

Error: Error: An error happened when parsing the getSystemOcrData, see: Error: An error happened when parsing the getSystemOcrData, see: Error: Invalid character in entity name Line: 224 Column: 2 Char:
