Parameters ---------- path_or_buffer : str or file-like This can be either a string of raw XML, a valid URL, file or file-like object. index : bool Whether to include index in xml document. row_name : str Name for root of xml document. Default is 'data'. root_name : str Name for row elements of xml document. Default is 'row'. na_rep : str Missing data representation. attrs_cols : list List of columns to write as attributes in row element. elem_cols : list List of columns to write as children in row element. namespacess : dict The namespaces to define in XML document as dicts with key being namespace and value the URI. prefix : str The prefix for each element in XML document including root. encoding : str Encoding of xml object or document. xml_declaration : bool Whether to include xml declaration at top line item in xml. pretty_print : bool Whether to write xml document with line breaks and indentation. stylesheet : str or file-like A URL, file, file-like object, or a raw string containing XSLT. compression : {'infer', 'gzip', 'bz2', 'zip', 'xz', None}, default 'infer' Compression type for on-the-fly decompression of on-disk data. If 'infer', then use extension for gzip, bz2, zip or xz. storage_options : dict, optional Extra options that make sense for a particular storage connection, e.g. host, port, username, password, etc., See also -------- pandas.io.formats.xml.EtreeXMLFormatter pandas.io.formats.xml.LxmlXMLFormatter NT�data�row�utf-8�inferr zFilePathOrBuffer | Nonez bool | Nonez str | Nonezlist[str] | Nonez dict[str | None, str] | None�strr r �None)�frame�path_or_buffer�index� root_name�row_name�na_rep� attr_cols� elem_cols� namespaces�prefix�encoding�xml_declaration� pretty_print� stylesheet� compression�storage_options�returnc C s| || _ || _|| _|| _|| _|| _|| _|| _| | _| | _ | | _ | | _ | | _ || _ || _|| _| j j�� | _| �� | _d S )N)r r r r r r r r r r r r r r! r" r# �columns�tolist� orig_cols�process_dataframe� frame_dicts)�selfr r r r r r r r r r r r r r! r" r# � r+ �K/home/digitalm-up/venv/lib/python3.7/site-packages/pandas/io/formats/xml.py�__init__Z s$ zBaseXMLFormatter.__init__�bytes)r$ c C s t | ��dS )z� Build tree from data.
