Delete erroring when id's are numeric

PySolr 3.10.0 running under Python 3.11.7, installed on MacOS via homebrew. Delete was failing when IDs were numeric: `id_list = [1,2,3,4] solr.delete(id = id_list)` This was working in 3.9.0. Breaks in 3.10.0. I played around with this a bit, and noticed 3.10.0 moved from "hand-generating" the XML doc to using xml.etree.ElementTree. Pulled this from 3.10.0 and ran it as a standalone snippet: ```python from xml.etree import ElementTree et = ElementTree.Element("delete") id_list = [1,2,3,4] for one_doc_id in id_list: subelem = ElementTree.SubElement(et, "id") subelem.text = one_doc_id m = ElementTree.tostring(et) ``` This results in: ```python Traceback (most recent call last): File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 1028, in _escape_cdata if "&" in text: ^^^^^^^^^^^ TypeError: argument of type 'int' is not iterable During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/Users/a3lrxzz/PYTHON/test.py", line 8, in <module> m = ElementTree.tostring(et) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 1098, in tostring ElementTree(element).write(stream, encoding, File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 743, in write serialize(write, self._root, qnames, namespaces, File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 906, in _serialize_xml _serialize_xml(write, e, qnames, None, File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 904, in _serialize_xml write(_escape_cdata(text)) ^^^^^^^^^^^^^^^^^^^ File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 1036, in _escape_cdata _raise_serialization_error(text) File "/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/xml/etree/ElementTree.py", line 1018, in _raise_serialization_error raise TypeError( TypeError: cannot serialize 1 (type int) ``` If I add the following map statement, to swap int's to str's, it works: ```python from xml.etree import ElementTree et = ElementTree.Element("delete") id_list = [1,2,3,4] id_list = list(map(str, id_list)) for one_doc_id in id_list: subelem = ElementTree.SubElement(et, "id") subelem.text = one_doc_id m = ElementTree.tostring(et) ``` Printing "m" here gives me: ``` <delete><id>1</id><id>2</id><id>3</id><id>4</id></delete> ```
