如何在 Python 中通过删除空格来压缩 XML 数据

from lxml import etree

def compress_xml_whitespace(input_bytes: io.BytesIO) -> io.BytesIO:
    """
    Compresses the whitespace in an XML file.
    Args:
        input_bytes (io.BytesIO): The input BytesIO object containing the XML content.
    Returns:
        io.BytesIO: The output BytesIO object containing the compressed XML content.
    """
    input_bytes.seek(0)  # Reset the position to the beginning of the BytesIO object

    parser = etree.XMLParser(remove_blank_text=True)
    tree = etree.parse(input_bytes, parser)

    # Convert the XML tree to a string without pretty printing (no newlines or indentation)
    compressed_xml = etree.tostring(tree, pretty_print=False, encoding='utf-8')

    # Write the compressed XML to the BytesIO output
    output_bytesio = io.BytesIO(compressed_xml)
    # Reset the pointer of the output BytesIO to the beginning
    output_bytesio.seek(0)
    return output_bytesio
