Find node from known starting point in totally dynamic webpage using c# and XPath? -


i trying write automated smoketest internal website. problem website dynamically generated. kind of unique identifier id combination of known string prefix , ends radomized number.

i can not depend on order, using things div[2] or span[25] not reliable, unless there way grab count of span/div/input based on located in dom known text value.

for example can find known text value. if can somehow programatically determine span known text value 55 , , know nested 2 deep other element looking for, "//span[55 - 2]/input".

the best can navigate dom known text value, , work or down there.

given that, in example below, how navigate input element, when starting known text value???

<span id="randomlygenerated35673">  	<span id="randomlygeneratednum58532">  		<span id="randomlygenerated78539">  			<span/>  			<span/>  			<span id="randomlygenerated78539">known text value</span>  		</span>  	</span>  	<input class="generic-non-unique" type="button" value="generic-non-unique"/>  </span>

you can use following axis:

//span[. = 'known text value']/following::input[@type = 'button']
