Some simple javascript xpath examples (See related posts)

var canCElC = document.evaluate( '//a[@class="canc"]' ,document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null );

for (var m = 0; m < canCElC.snapshotLength; m++){

	var im = canCElC.snapshotItem(m);

}

var mems = document.evaluate( '//a[contains(@href, "profile")][ not( @class = "skyblue" )]' ,document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null );

for (var l = 0; l < mems.snapshotLength; l++){

	var cThis = mems.snapshotItem(l);

}	

var canHazPics = document.evaluate( '//a[@title= "Click for large image"]' ,document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue;

document.evaluate( 'html/body/div/div[7]/table/tbody/tr[2]/td[ not( contains(@id, "main") )]' ,document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null );
