Improve readability of XML responses, SOAP envelopes, and Android resources by breaking between tags. Does not validate against XSD or perform entity expansion.
Quick answer: XML Formatter
Inserts line breaks between XML tags for SOAP and Android resource skims.
Example: `<Envelope><Body><m>1</m></Body></Envelope>` becomes easier to eyeball in incident bridges.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Does not fetch XSDs or expand entities - treat as a reading aid before your XML editor validates structure.

This pass focuses on tag line breaks; deep indenting may still need an IDE.
Left intact as single blocks when no inner `><` splits exist.
Consider streaming parsers server-side for multi-megabyte XML.
Never paste secret keys into shared machines.
HTML is looser; use the HTML formatter for mixed documents.
Inserts line breaks between XML tags for SOAP and Android resource skims.
