Wrap literal xml input in ``io.StringIO`` or ``io.BytesIO`` instead. xpath : str, optional, default './\*' The ``XPath`` to parse required set of nodes for migration to :class:`~pandas.DataFrame`.``XPath`` should return a collection of elements and not a single element. Note: The ``etree`` parser supports limited ``XPath`` expressions. For more complex ``XPath``, use ``lxml`` which requires installation. namespaces : dict, optional The namespaces defined in XML document as dicts with key being namespace prefix and value the URI. There is no need to include all namespaces in XML, only the ones used in ``xpath`` expression. Note: if XML document uses default namespace denoted as `xmlns=''` without a prefix, you must assign any temporary namespace prefix such as 'doc' to the URI in order to parse underlying nodes and/or attributes. For example, :: namespaces = {{"doc": "https://example.com"}} elems_only : bool, optional, default False Parse only the child elements at the specified ``xpath``. By default, all child elements and non-empty text nodes are returned. attrs_only : bool, optional, default False Parse only the attributes at the specified ``xpath``. By default, all attributes are returned. names : list-like, optional Column names for DataFrame of parsed XML data. Use this parameter to rename original element names and distinguish same named elements and attributes. dtype : Type name or dict of column -> type, optional Data type for data or columns. E.g. {{'a': np.float64, 'b': np.int32, 'c': 'Int64'}} Use `str` or `object` together with suitable `na_values` settings to preserve and not interpret dtype. If converters are specified, they will be applied INSTEAD of dtype conversion. .. versionadded:: 1.5.0 converters : dict, optional Dict of functions for converting values in certain columns. Keys can either be integers or column labels. .. versionadded:: 1.5.0 parse_dates : bool or list of int or names or list of lists or dict, default False Identifiers to parse index or columns to datetime. The behavior is as follows: * boolean. If True -> try parsing the index. * list of int or names. e.g. If [1, 2, 3] -> try parsing columns 1, 2, 3 each as a separate date column. * list of lists. e.g. If [[1, 3]] -> combine columns 1 and 3 and parse as a single date column. * dict, e.g. {{'foo' : [1, 3]}} -> parse columns 1, 3 as date and call result 'foo' .. versionadded:: 1.5.0 encoding : str, optional, default 'utf-8' Encoding of XML document. parser : {{'lxml','etree'}}, default 'lxml' Parser module to use for retrieval of data. Only 'lxml' and 'etree' are supported. With 'lxml' more complex ``XPath`` searches and ability to use XSLT stylesheet are supported. stylesheet : str, path object or file-like object A URL, file-like object, or a raw string containing an XSLT script. This stylesheet should flatten complex, deeply nested XML documents for easier parsing. To use this feature you must have ``lxml`` module installed and specify 'lxml' as ``parser``. The ``xpath`` must reference nodes of transformed XML document generated after XSLT transformation and not the original XML document. Only XSLT 1.0 scripts and not later versions is currently supported. iterparse : dict, optional The nodes or attributes to retrieve in iterparsing of XML document as a dict with key being the name of repeating element and value being list of elements or attribute names that are descendants of the repeated element. Note: If this option is used, it will replace ``xpath`` parsing and unlike ``xpath``, descendants do not need to relate to each other but can exist any where in document under the repeating element. This memory- efficient method should be used for very large XML files (500MB, 1GB, or 5GB+). For example, :: iterparse = {{"row_element": ["child_elem", "attr", "grandchild_elem"]}} .. versionadded:: 1.5.0 {decompression_options} .. versionchanged:: 1.4.0 Zstandard support. {storage_options} dtype_backend : {{'numpy_nullable', 'pyarrow'}}, default 'numpy_nullable' Back-end data type applied to the resultant :class:`DataFrame` (still experimental). Behaviour is as follows: * ``"numpy_nullable"``: returns nullable-dtype-backed :class:`DataFrame` (default). * ``"pyarrow"``: returns pyarrow-backed nullable :class:`ArrowDtype` DataFrame. .. versionadded:: 2.0 Returns ------- df A DataFrame. See Also -------- read_json : Convert a JSON string to pandas object. read_html : Read HTML tables into a list of DataFrame objects. Notes ----- This method is best designed to import shallow XML documents in following format which is the ideal fit for the two-dimensions of a ``DataFrame`` (row by column). :: data data data ... ... ... As a file format, XML documents can be designed any way including layout of elements and attributes as long as it conforms to W3C specifications. Therefore, this method is a convenience handler for a specific flatter design and not all possible XML structures. However, for more complex XML documents, ``stylesheet`` allows you to temporarily redesign original document with XSLT (a special purpose language) for a flatter version for migration to a DataFrame. This function will *always* return a single :class:`DataFrame` or raise exceptions due to issues with XML document, ``xpath``, or other parameters. See the :ref:`read_xml documentation in the IO section of the docs ` for more information in using this method to parse XML files to DataFrames.
