XML Entity Escaper & Unescaper
XML Entity Escaper & Unescaper: Replaces `<`, `>`, `&`, `"`, and `'` with XML standard entities `<`, `>`, `&`, `"`, `'`.
About this xml entity escaper & unescaper
XML Entity Escaper & Unescaper — browser-based utility.
How this tool works
Implements client-side XML Entity Escaper & Unescaper operations. Replaces `<`, `>`, `&`, `"`, and `'` with XML standard entities `<`, `>`, `&`, `"`, `'` specifically designed for an xml developer escapes xml reserved entities before embedding user text into an xml cdata section.
- Stream Byte Decoding: Converts input text into UTF-8 binary octet arrays via native TextEncoder / Uint8Array APIs.
- Bit Manipulation & Sextet Packing: Slices binary byte streams into 6-bit chunks, translating them against Base64 index lookup tables.
- Lempel-Ziv / Huffman Encoding: Applies LZ77 sliding-window dictionary compression and Huffman trees for DEFLATE/GZIP payloads.
- Integrity Verification: Validates complete round-trip reversibility, verifying that decoded bytes match original inputs byte-for-byte.
Worked example
Scenario: Escape reserved characters in a fixed XML text fragment.
Sample input:
Processing: The XML branch replaces reserved characters with predefined entities; it does not parse or validate a complete XML document.
Illustrative output:
Limits and verification
Rejects malformed Base64 containing invalid characters or incorrect padding lengths. In URL decoding, rejects incomplete or truncated percent sequences (such as '%2' or '%ZZ').
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
Which XML characters are escaped?+
The XML mode replaces reserved text characters such as angle brackets and ampersand using XML entities, with a decode branch for entity text.
What did the browser fixture verify?+
<root>CZOA & tools</root> produced escaped root brackets and an & entity.
Does escaping validate an XML document?+
No. It transforms text; it does not prove namespaces, document structure, schemas, or parser acceptance.
How is reverse conversion chosen?+
Second input decode or unescape selects the reverse entity-replacement path.
