Function xsltTestMatchPattern 

pub unsafe fn xsltTestMatchPattern(
    node: *mut _xmlNode,
    pattern_node: *mut _xmlNode,
) -> bool

Test whether a node matches a compiled pattern tree.

In libxslt, the match attribute is compiled into a tree of _xmlNode elements during stylesheet compilation. This function walks that tree to determine whether node matches the pattern.

The pattern tree structure uses element nodes where:

• The node name encodes the step type (element name, “*”, “node()”, etc.)
• Children represent path steps (inner to outer)
• Siblings at the root level represent union alternatives

Parameters

• node — The document node to test.
• pattern_node — The compiled pattern tree root (from _xsltTemplate.r#match).

Returns

true if the node matches, false otherwise.

Safety

Both pointers must be valid (or null — null pointers return false).
