About XML Parser

XML (Extensible Markup Language) is the backbone of countless data exchange formats — SOAP web services, RSS and Atom feeds, SVG graphics, Android manifest files, Maven build configurations, Microsoft Office documents (OOXML), and proprietary enterprise APIs all rely on XML. When you receive a raw XML document, it reads as a wall of angle brackets and nesting levels that are difficult to follow by eye. The XML Parser converts that raw text into an interactive, collapsible tree so you can see exactly how elements, attributes, and text nodes relate to each other without writing a single line of code.

Every node in the tree is color-coded: element tag names appear in blue, attribute names in amber, attribute values in orange, and text content in green. Parent nodes show a child-count badge before you expand them so you know how many items to expect. You can expand or collapse any branch independently, which is especially useful for large SOAP envelopes or deep configuration files where you only need to inspect one section at a time. The tool also accepts .xml, .svg, .xsl, and .xslt file uploads so you can load documents directly from disk without copy-pasting.

All parsing runs entirely inside your browser using the native DOMParser API — the same engine your browser uses to render web pages. No XML is uploaded, transmitted, or logged anywhere. This makes the tool safe for confidential enterprise payloads, internal API responses, and any document you would rather not send to a third-party service. There is no sign-up, no rate limit, and no cost.

Key Features

check_circle

Color-coded tree view

Element names display in blue, attribute names in amber, attribute values in orange, and text content in green. Type and role are visible at a glance without hovering or selecting anything.

check_circle

Expand and collapse any branch

Every element with children gets a toggle arrow. You can open only the section you care about and collapse everything else, which keeps deeply nested documents manageable.

check_circle

Child-count badges

Parent nodes show the number of direct child elements in a small badge before you expand them, so you can gauge the size of a subtree and decide whether to drill in.

check_circle

File upload for .xml, .svg, .xsl, and .xslt

Load files directly from your device without copying their content first. Useful for large configuration files or generated XML that would be tedious to paste manually.

check_circle

Inline syntax-error reporting

If your XML is malformed — unclosed tags, mismatched element names, invalid characters — a red error bar immediately shows the DOMParser's error message so you know exactly where the problem is.

check_circle

100% client-side, no uploads

Parsing happens in your browser using the native DOMParser API. SOAP payloads, API credentials, and enterprise data never leave your machine.

How to Use

01

Paste or Upload XML

Paste your raw XML into the input pane, or click the upload button to load an .xml file from your device.

02

Click Parse

Hit the "Parse" button to run the XML through the browser's DOMParser. Any syntax errors will be shown in the error bar.

03

Explore the Tree

Browse the interactive tree view on the right. Click the arrows to expand or collapse nodes and inspect elements, attributes, and text content.

Example

A bookstore XML document is parsed into a tree. The root element expands to show two book child elements, each with category and lang attributes in amber and title/author/year as leaf nodes with green text content.

Common Use Cases

  • arrow_circle_right

    Inspecting SOAP and REST XML API responses

    Enterprise APIs often return deeply nested SOAP envelopes or verbose XML payloads. Paste the raw response to immediately see the element hierarchy, locate the value you need, and understand the namespace structure — without writing an XPath query first.

  • arrow_circle_right

    Debugging RSS and Atom feeds

    Feed parsers are strict about element ordering and namespaces. Use the tree view to confirm that your channel, item, and entry elements are in the right positions and that required attributes like type and href are present on the correct nodes.

  • arrow_circle_right

    Exploring Android manifest and Maven POM files

    AndroidManifest.xml and pom.xml files grow long and deeply nested over time. The collapsible tree lets you focus on a single activity declaration or dependency block without scrolling past hundreds of unrelated lines.

  • arrow_circle_right

    Validating SVG and XSLT structure

    SVG and XSLT are both XML dialects with their own element rules. Parsing them as a tree helps you spot misplaced defs, incorrect template match attributes, or missing namespace declarations before running a transformation or rendering in a browser.

  • arrow_circle_right

    Learning and teaching XML document structure

    The color-coded tree makes the parent-child relationship between elements visual and intuitive. Students and developers new to XML can paste any document and immediately see which nodes are elements, which are attributes, and how text content sits inside leaf nodes.

Frequently Asked Questions

What is an XML Parser? expand_more
An XML parser reads raw XML text and converts it into a structured document object model (DOM) tree. Each XML element becomes a node in the tree, with its attributes, text content, and child elements accessible for inspection. This makes it easy to understand and navigate complex XML documents.
What types of XML files are supported? expand_more
The parser supports any well-formed XML document, including configuration files, SOAP responses, SVG markup, XSLT stylesheets, RSS/Atom feeds, Maven POM files, Android manifests, and custom XML formats. As long as the XML follows proper syntax rules, it can be parsed and displayed as a tree.
Is my XML data kept private? expand_more
Yes. All parsing is performed locally in your browser using the native DOMParser API. Your XML data never leaves your device and is not sent to any external server, making it completely safe for sensitive or proprietary content.
How are parsing errors handled? expand_more
If your XML contains syntax errors such as unclosed tags, mismatched element names, or invalid characters, the parser detects the issue through the DOMParser error reporting and displays a descriptive error message in the red error bar above the editor panes.
How is the XML Parser different from the XML Formatter? expand_more
The XML Formatter is for beautifying or minifying the raw XML text itself — it adjusts indentation and whitespace but leaves the raw markup as text. The XML Parser goes a step further: it interprets the document structure and renders it as an interactive tree where you can expand and collapse individual elements, inspect attribute values, and navigate the hierarchy visually. Use the Formatter to clean up indentation; use the Parser to understand and explore the document structure.
How is this different from the JSON Viewer? expand_more
The JSON Viewer parses JSON syntax (curly braces, square brackets, quoted keys) into a tree using JavaScript's JSON.parse. The XML Parser handles XML syntax — angle-bracket tags, attributes, namespaces, and processing instructions — using the browser's DOMParser. The two tools share a similar tree-view metaphor but operate on entirely different data formats with different parsing rules.
Can I parse SVG or XSLT files? expand_more
Yes. SVG and XSLT are both XML dialects, and the parser accepts them alongside standard XML. You can also upload files with .svg, .xsl, or .xslt extensions directly via the upload button. The tree view will display all elements and attributes exactly as they appear in the document.
Is there a file size limit? expand_more
There is no built-in limit. Because everything runs locally in your browser, performance for very large files depends on your device's memory and processing speed rather than any server restriction. Most configuration files and API payloads parse in well under a second.
