ale-delfino	0df76bee37	core[patch]:: XML parser to cover the case when the xml only contains the root level tag (#17456 ) Description: Fix xml parser to handle strings that only contain the root tag Issue: N/A Dependencies: None Twitter handle: N/A A valid xml text can contain only the root level tag. Example: <body> Some text here </body> The example above is a valid xml string. If parsed with the current implementation the result is {"body": []}. This fix checks if the root level text contains any non-whitespace character and if that's the case it returns {root.tag: root.text}. The result is that the above text is correctly parsed as {"body": "Some text here"} @ale-delfino Thank you for contributing to LangChain!
