class_docstr: Internal subclass to parse XML into DataFrames.
  
  Parameters
  ----------
  path_or_buffer : a valid JSON str, path object or file-like object
      Any valid string path is acceptable. The string could be a URL. Valid
      URL schemes include http, ftp, s3, and file.
  
  xpath : str or regex
      The XPath expression to parse required set of nodes for
      migration to `Data Frame`. `etree` supports limited XPath.
  
  namespaces : dict
      The namespaces defined in XML document (`xmlns:namespace='URI')
      as dicts with key being namespace and value the URI.
  
  elems_only : bool
      Parse only the child elements at the specified `xpath`.
  
  attrs_only : bool
      Parse only the attributes at the specified `xpath`.
  
  names : list
      Column names for Data Frame of parsed XML data.
  
  dtype : dict
      Data type for data or columns. E.g. {{'a': np.float64,
      'b': np.int32, 'c': 'Int64'}}
  
      .. 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
      Converts either index or select columns to datetimes
  
      .. versionadded:: 1.5.0
  
  encoding : str
      Encoding of xml object or document.
  
  stylesheet : str or file-like
      URL, file, file-like object, or a raw string containing XSLT,
      `etree` does not support XSLT but retained for consistency.
  
  iterparse : dict, optional
      Dict with row element as key and list of descendant elements
      and/or attributes as value to be retrieved in iterparsing of
      XML document.
  
      .. versionadded:: 1.5.0
  
  {decompression_options}
  
      .. versionchanged:: 1.4.0 Zstandard support.
  
  {storage_options}

  Notes
  -----
  To subclass this class effectively you must override the following methods:`
      * :func:`parse_data`
      * :func:`_parse_nodes`
      * :func:`_iterparse_nodes`
      * :func:`_parse_doc`
      * :func:`_validate_names`
      * :func:`_validate_path`
  
  
  See each method's respective documentation for details on their
  functionality.
docstr: Validate xpath.
  
  This method checks for syntax, evaluation, or empty nodes return.
  
  Raises
  ------
  SyntaxError
      * If xpah is not supported or issues with namespaces.
  
  ValueError
      * If xpah does not return any nodes.
