While translating XML files,
Site Translator converts the text between XML tags - not the text included in the attributes.
For example if a XML file contains the following text:
<products>
<product1>This is a test product.</product1>
<descriptionSample>usage of the product.</description>
<card_securityCard>Security Code</card_security>
</products>
Then the text "This is a test product.", "Sample usage of the product.", and "Card Security Code" will get translated.
