regex - Xpath to find prices in a web page -

i trying extract prices , currency in html page (for exampe this webpage) using xpath expression.

i tried:

$x("//*[matches(text(),'^\$\d+\.\d{1,2}')]")

in firefox's console prints undefined. solution based on regular expressions.

from example, because use matches, deduce use xpath 2. probably, not supported browser. check xpath version.

another version work xpath 1 described below.

notice xpath <span> elements looks like:

//*[@id="result_0"]/div/div[3]/div[1]/a/span //*[@id="result_1"]/div/div[3]/div[1]/a/span //*[@id="result_2"]/div/div[3]/div[1]/a/span

so, need use regular expression id , text span.

you can use matches (xpath2) or starts-with (xpath1) first part , text() text span. so, test in browser, use this:

$x('//*[starts-with(@id,"result_")]/div/div[3]/div[1]/a/span/text()')
