Get more from XPath Tester
XPath Tester helps you test XPath selections in XML. XPath addresses nodes in an XML tree, making it useful for selecting elements, attributes, and text by their structural position. This is useful when the information is already available but its structure, presentation, or consistency makes it difficult to inspect. Work with a representative sample first so that you can recognize the expected result before applying the same operation to a larger document. Namespaces can require prefixes in an XPath expression even when the source uses a default namespace. Supported XPath versions also differ. Keep the original input available while reviewing the output. The important check is whether the result still has the intended values and relationships, rather than whether it merely looks neater. Check whether your expression returns nodes, text, a number, or a boolean.

How to use this tool
- Place the XML input in the relevant editor. If the tool compares or combines documents, keep each document in its own input.
- Select the available settings for the operation you need. Check whether your expression returns nodes, text, a number, or a boolean.
- Review any syntax errors before interpreting the result. A valid document with the wrong structure needs a different fix from malformed input.
- Inspect the changed portion and at least one unchanged portion. Keep a copy of the original XML until the result has been checked in its destination.
SEE IT IN PRACTICE
A worked example
<root><name>Ada</name></root>; XPath /root/name/text()
Ada
The expression starts at the document root, selects name under root, and returns its text node.
Namespaces and node kinds
An unprefixed element in a document with a default namespace is still namespaced. XPath expressions may need an explicitly bound prefix to match it. Elements, attributes, and text are distinct node kinds: selecting an element is not always equivalent to selecting its text. Reduce an empty result to one element and namespace before expanding a complex expression.
Attributes, elements, and text return different nodes
The expression /root/name selects an element, /root/name/text() selects its text, and /root/@id selects an attribute on root. Choose the node kind that the receiving workflow expects. A result viewer may display these similarly even though their types differ. Test both a missing node and repeated matching nodes so that your extraction does not silently assume exactly one value will always exist.
When this tool is useful
- Inspect XML response fields while keeping the underlying structure visible.
- Reproduce an empty node selection with a compact, reproducible sample.
- Develop extraction expressions before copying data into another application.
Tips for a better result
- Namespaces can require prefixes in an XPath expression even when the source uses a default namespace. Supported XPath versions also differ.
- Check whether your expression returns nodes, text, a number, or a boolean.
- Use a small XML example to isolate an unexpected result. Add nested objects, arrays, quoted text, and empty values only as needed to reproduce the behavior.
Frequently asked questions
Does this establish that my XML is correct?
It checks or transforms the aspects covered by this operation. It cannot establish whether the values match your business rules, whether required records are missing, or whether the receiving application accepts the same structure.
Why do visually similar inputs behave differently?
Value types, nesting, array order, duplicate names, and invisible whitespace inside strings can carry meaning. Compare the parsed structure and exact values, rather than judging only the way the document appears on screen.
What is a useful review process?
First resolve syntax errors, then inspect the specific result this tool produces. Check whether your expression returns nodes, text, a number, or a boolean. Finally, test a representative result with the application that will consume it.
What happens to the information I enter?
The utility processes your input in this browser. Some tools retain field values in browser storage or the URL; avoid entering secrets in shareable fields. Page and asset requests still go to the hosting provider. Read the privacy and offline-use notes for details.
