xpath - HtmlUnit getByXpath returns null -


i coding groovy, however, don't believe language specific set of questions.

i have 2 questions

first question

i've run issue while using htmlunit. telling me trying grab null.

the page i'm testing on is: http://browse.deviantart.com/resources/applications/psbrushes/?order=9&offset=0#/dbwam4

my code:

client = new webclient(browserversion.firefox_3) client.javascriptenabled = false  page = client.getpage(url)  //coming null title = page.getbyxpath("//html/body/div[4]/div/div[3]/div/div/div/div/div/div/div/div/div/div/h1/a")  println title

this prints out: []

is because page uses onclick()? if so, how around that? enabling javascript creates mess in cmd prompt.

second question

i wanting image having trouble because when attempt xpath (via firebug) shows as: //*[@id="gmi-resviewsizer_img"]

how handle that?

first answer: 

/html/body/div[3]/div/div[3]/div/div/div/div/div/div/div/div/div/div/h1/a

your xpath off 1 in predicate filter 4th div of body, should 3rd div. appears html site can/does change when had origionally snagged xpath using firebug. may need adjust xpath accommodate potential change , less sensitive differences in document structure.

maybe this:

/html/body//div/h1/a

second answer: xpath listed work. may odd/short(and may not efficient), // starts @ root node , looks throughout every node in tree, * matches on element(to include img) , [] predicate filter restricts have id attribute who's value equals "gmi-resviewsizer_img".

there many other options xpaths work well. depend on how html structure changes. 1 works page referenced select img:

/html/body/div/div/div/div/img[1]
