HasXPath

public HasXPath(java.lang.String xPathExpression,
                Matcher<java.lang.String> valueMatcher)

Parameters:

xPathExpression - XPath expression.

valueMatcher - Matcher to use at given XPath. May be null to specify that the XPath must exist but the value is irrelevant.

HasXPath

public HasXPath(java.lang.String xPathExpression,
                javax.xml.namespace.NamespaceContext namespaceContext,
                Matcher<java.lang.String> valueMatcher)

Parameters:

xPathExpression - XPath expression.

namespaceContext - Resolves XML namespace prefixes in the XPath expression

Method Detail

matchesSafely

public boolean matchesSafely(org.w3c.dom.Node item,
                             Description mismatch)

Description copied from class: TypeSafeDiagnosingMatcher

Subclasses should implement this. The item will already have been checked for the specific type and will never be null.

Specified by:

matchesSafely in class TypeSafeDiagnosingMatcher<org.w3c.dom.Node>

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.

Parameters:

description - The description to be built or appended to.

hasXPath

public static Matcher<org.w3c.dom.Node> hasXPath(java.lang.String xPath,
                                                 Matcher<java.lang.String> valueMatcher)

Creates a matcher of Nodes that matches when the examined node has a value at the specified xPath that satisfies the specified valueMatcher. For example:

assertThat(xml, hasXPath("/root/something[2]/cheese", equalTo("Cheddar")))

Parameters:

xPath - the target xpath

valueMatcher - matcher for the value at the specified xpath

hasXPath
