Important: requires you to have libxml2 installed
build dependencies:
- clang
- pkg-config
- libxml2 (installed system-wide)
Example
var parsed = parseHTML("<html><body><h1>foobar</h1></body></html>", "")
var nodes : seq[HTMLNode] = toSeq(xpathQuery(parsed, "//*"))
assert map(nodes, (n) => n.node_name.get) == @["html", "body", "h1"]
for node in xpathQuery(parsed, "//*"):
if node.node_name.isSome and node.node_name.get == "h1":
assert node.textContent.get == "foobar"Example using queryWithContext to query against subnodes.
var parsed = parseHTML("<html><body><h3>foobar</h3><h3>sdasdasd</h3><div><span>this is a span</span><span>this is another span</span></div><h1 id='some_id' class='header1'>foo bar baz</h1></body></html>")
for node in xpathQuery(parsed, "//div"):
for subnode in queryWithContext(node, ".//*"):
assert $subnode.node.name == "span"See the tests for more detailed examples. You can run the tests with nimble test.
I have also written up a quick guide here with a more detailed explanation of how the library works.
To install, add nimpath to your .nimble file, and make sure clang is installed. If you installed libxml2 using something other than your package manager, it may require setting the linker flags in config.nims manually and/or using LD_LIBRARY_PATH.
You must also add this code to config.nims to get it to build.
