About XML Viewer
Reading XML as a wall of text means tracking nesting by counting angle brackets. Presented as a tree it collapses to the level you care about, which is what makes locating a single element in a feed of several thousand practical at all. It is free to use online. The document is read in this page instead of being uploaded, and no sign up stands between you and the tree.
How to use XML Viewer
- Load the documentFeeds, sitemaps, API responses and configuration are all ordinary XML and all open here.
- Collapse the parts you are not readingThe structure stays easy to move around however many thousand lines the document runs to.
- Inspect attributes in placeThey are shown beside their element rather than hidden inside the tag text.
Namespaces, and why an element has a prefix
A prefix like dc: or atom: binds an element to a namespace declared higher up the document, which is how two vocabularies coexist in one file without their element names colliding. The tree shows the prefix as written, because stripping it would hide the thing that tells you which specification an element belongs to.
What it does not do
- Built for reading rather than rewriting. If you want reformatted markup handed back, the XML Beautifier is the page that does that.
- A very large document has to fit in the tab, so the ceiling is your machine rather than anything imposed here.
XML Viewer: questions people ask
- Can I open a sitemap or an RSS feed with this?
- Yes. Both are ordinary XML, and the tree view makes the repeated entry structure easy to scan for the one that looks wrong.
- Is the file uploaded?
- No. Everything is parsed locally, and that matters when the document happens to be a response full of customer records.
- Do I need to download an XML viewer for Windows 11?
- No installation is needed. The viewer is this web page, so Chrome, Edge, Firefox or Safari on Windows 11, Mac or Linux is all it needs. It opens .xml, .xsd, .xsl, .svg, .rss and .atom files up to 20 MB, and the formatted result can be downloaded as a new XML file.
