Frequently Asked Questions

No. ToolZeno operations are completely local and client-side. The DOM parsing, structural validation, and diffing calculations run inside your browser using JavaScript. No document content is uploaded or transmitted, ensuring complete confidentiality for database exports, API schema specifications, or server configuration files.

XPaths are standard XML address pointers showing exactly where a change is located. They indicate the path from the root tag down to the specific node or attribute (e.g. `/catalog/book[2]/@id` for an attribute or `/catalog/book[1]/title/text()[1]` for a text node value). This makes locating discrepancies in large nested schemas straightforward.

ToolZeno implements a Longest Common Subsequence (LCS) alignment algorithm for child nodes. If an element is added or removed in the middle of a list, the engine aligns matching elements instead of shifting them all and flagging everything as modified. This ensures extremely clean, logical difference metrics.

Yes, you have full control. You can choose to ignore whitespace changes (trimming tags and values), ignore XML comment tags (`<!-- comment -->`), and ignore attribute order (attributes like `id="1" name="a"` and `name="a" id="1"` will be matched as identical). Check these options in the settings toolbar before running the compare.
