What XPath Tester does
XPath Tester on CodeBeautify is a web-based utility for validating and refining XPath expressions against XML or HTML content. Users supply source data via pasted text, uploaded file, or a URL, then enter an XPath query to see which nodes match. The tool returns a list of selected elements with line and column positions, helping users confirm that their path logic correctly targets the intended data before deploying it in scripts or stylesheets.
How to use the CodeBeautify XPath Tester
- 1
Paste or upload your XML or HTML source data into the designated input field.
- 2
Enter the XPath expression you want to test in the XPath Expression box.
- 3
Click the Test XPath button to execute the query against your data.
- 4
Review the output panel which lists matching elements with their line and column numbers.
- 5

Best for
Developers and web scraping engineers who need to quickly verify that an XPath expression correctly selects desired nodes in XML or HTML structures without writing code.
Limitations
- Results depend on the accuracy of the uploaded or pasted source data.
- The interface does not display a visual tree view of the selected nodes.
- Namespace handling requires explicit prefix declarations in the expression.
XPath Tester FAQ
- Can I test XPath expressions that use XML namespaces?
- Yes, the tool supports namespace prefixes. You must declare the namespace prefixes (e.g., xmlns:foo) in the sample XML section and use the prefix syntax in your XPath expression, such as //foo:company, to select namespaced elements correctly.
- What happens if my XPath expression has a syntax error?
- The tool will highlight the error and return an empty or partial result list, allowing you to identify and fix the problematic syntax before finalizing your query.
- Is there a limit to the size of the XML file I can upload?
- The material does not specify a file size limit; very large files may cause performance issues or timeout depending on browser capacity.
- Can I save or share my tested XPath expressions?
- The interface includes a Save & Share feature, enabling you to preserve your expression and sample data for later use or to send to collaborators.
