Formatter

✓ from xmlformatter import Formatter

✗ from xmlformatter import XmlFormatter

Initialize a formatter, format an XML string, and print the pretty-printed result.

from xmlformatter import XmlFormatter formatter = XmlFormatter(indent=' ', encoding_output='UTF-8', preserve_declaration=True) xml_string = '<root><child>text</child></root>' pretty = formatter.format_string(xml_string) print(pretty) # Output: # <?xml version="1.0" encoding="UTF-8"?> # <root> # <child>text</child> # </root>

Debug

Known issues

gotchaThe 'preserve_declaration' parameter only preserves an existing XML declaration; it does not add one if missing. To force a declaration, set 'xml_declaration' parameter instead.

fix

Use formatter = XmlFormatter(xml_declaration=True) to always output declaration.

affects: all

gotchaThe 'indent' parameter defaults to 4 spaces. If you set indent to something else, ensure it's a string of spaces or a single tab. Numeric values may cause unexpected behavior or errors.

fix

Use indent='  ' or indent='\t' explicitly as a string.

affects: all

deprecatedThe parameter 'preserve_whitespace' is no longer supported in version 0.2.9. Use 'preserve' instead.

fix

Replace preserve_whitespace=True with preserve=True in XmlFormatter constructor.

affects: >=0.2.9
