mendapatkan jenis elemen invaild DI SELENIUM
bekerja di Linux ubuntu 20.04 dengan intellij IDEA versi komunitas terbaru dengan firefox dan geckodriver
Saya mencoba untuk mendapatkan beberapa jadwal dari halaman web dan menyalinnya ke file .txt (atau daftar tidak masalah)
Saya mencoba ini:
WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(2000, TimeUnit.MILLISECONDS); //MAXIMUM WAIT TIME
driver.get("http://telematics.oasa.gr/#main");
driver.findElement(By.xpath("//option[contains(.,'021')]")).click();//selecting trip
List<WebElement> oas = driver.findElements(By.xpath("//div/ul/li"));
System.out.println(oas.size());
System.out.println(oas);
link halaman: http://telematics.oasa.gr/#lineDetails_1151_021%20:%20%CE%A0%CE%9B%CE%91%CE%A4%CE%95%CE%99%CE%91%20%CE%9A%CE%91%CE%9D%CE%99%CE%93%CE%93%CE%9F%CE%A3%20-%20%CE%93%CE%9A%CE%A5%CE%96H%20(%CE%9A%CE%A5%CE%9A%CE%9B%CE%99%CE%9A%CE%97)_9-86
berikut adalah html halaman tersebut:
<li class="list-group-item scheduleEntryL"><button type="button" class="btn btn-info btn-circle" style="cursor:default;">07</button> 07:10 07:25 07:40 07:55 </li>
dan setelah ini hasilnya adalah:
19

yang berarti daftar saya memiliki 19 elemen tetapi bukan itu yang saya inginkan
//RINGKASAN
- Jenis elemen yang saya dapatkan tidak tepat
daftar harus berisi:
[..., 07: 00,07: 10,07: 25, ....]
2. Harus berisi 59 elemen karena ada 59 keberangkatan yang diberikan di halaman tetapi beberapa di antaranya berada di baris yang sama
halaman ini memiliki 19 baris sehingga propably memberikan setiap baris sebagai SATU elemen dan ini juga bukan yang saya inginkan
TOLONG BANTU
// SAYA TELAH MEMERIKSA POSTINGAN YANG SAMA DI HALAMAN INI DAN TIDAK MEMBANTU
Jawaban
Anda menggunakan xpath yang akan mengembalikan baris dari halaman tetapi bukan elemen sebenarnya yang berisi nilai yang diperlukan. Juga nilai teks berada di antara dua node, jadi kita perlu menggunakan JavaScript untuk itu.
//Code to extract Departure time without *
List<WebElement> oas = driver.findElements(By.xpath("//li[@class='list-group-item scheduleEntryL']"));
LinkedList<String> timeValues = new LinkedList<String>();
String myCountryProxy = null;
for(WebElement element:oas)
{
//As text is between two nodes, we need to use javaScript as selenium getText() method didn't work for it
//So in below javaScript, we refer to oas as parent element as then we try to find node which contain text as childNode. In this code its 2nd child node so we have passed value as 1: childNodes[1]
myCountryProxy = ((JavascriptExecutor)driver).executeScript("return arguments[0].childNodes[1].textContent;", element).toString();
//Code to remove extra space from String
if(!myCountryProxy.equalsIgnoreCase(" "))
{
myCountryProxy = myCountryProxy.replaceAll(" "," ").replaceAll(" ","").replaceAll(" ","");
myCountryProxy = myCountryProxy.trim();
//Split string into individual value
String[] split = myCountryProxy.split("\\s+");
for(String str:split)
{
timeValues.add(str);
}
}
}
//Code to extract departure time values with *: 05:00*
oas = driver.findElements(By.xpath("//span[@class='xtra']"));
for(WebElement element:oas)
{
//here node which contains text is 1st child node only, so we have passed value as childNodes[0]
myCountryProxy = ((JavascriptExecutor)driver).executeScript("return arguments[0].childNodes[0].textContent;", element).toString();
timeValues.add(myCountryProxy);
}
//Code to extract departure values which are same line of time with * i.e.: 05:10 05:30 05:50
oas = driver.findElements(By.xpath("//li[@class='list-group-item scheduleEntryL']/span"));
if(oas.size()>0)
{
oas = driver.findElements(By.xpath("//li[@class='list-group-item scheduleEntryL']/span/.."));
for(WebElement element:oas)
{
//here node which contains text is 4th child node, so we have passed value as childNodes[4]
myCountryProxy = ((JavascriptExecutor)driver).executeScript("return arguments[0].childNodes[3].textContent;", element).toString();
//Code to remove extra space from String
if(!myCountryProxy.equalsIgnoreCase(" "))
{
myCountryProxy = myCountryProxy.replaceAll(" "," ").replaceAll(" ","").replaceAll(" ","");
myCountryProxy = myCountryProxy.trim();
//Split string into individual value
String[] split = myCountryProxy.split("\\s+");
for(String str:split)
{
timeValues.add(str);
}
}
}
}
System.out.println(timeValues);
Saya memiliki kode yang dieksekusi ini di akhir saya dan mendapatkan output di bawah ini:
[06:10, 06:25, 06:40, 06:55, 07:05, 07:15, 07:25, 07:35, 07:45, 07:55, 08:05, 08:20, 08:30, 08:40, 08:55, 09:05, 09:15, 09:30, 09:50, 10:10, 10:25, 10:45, 11:00, 11:20, 11:35, 11:55, 12:10, 12:30, 12:45, 13:20, 13:40, 13:55, 14:10, 14:25, 14:35, 14:45, 15:00, 15:10, 15:20, 15:35, 15:45, 15:55, 16:10, 16:20, 16:30, 16:45, 16:55, 17:05, 17:20, 17:35, 17:55, 18:15, 18:30, 18:45, 19:00, 19:20, 19:35, 19:55, 20:10, 20:25, 20:40, 21:00, 21:20, 21:40, 22:05, 22:30, 22:55, 05:00*, 23:20*, 05:10, 05:30, 05:50]
Harap dicatat, saya telah menambahkan nilai dari baris yang berisi waktu dengan *, di akhir daftar. Jadi, Anda akan menemukan nilai-nilai itu di akhir daftar.
Untuk mengekstrak teks antar node, saya mengacu pada: posting SO ini
Juga, jika Anda ingin memilih nilai drop-down, gunakan Selectkelas selenium:
Select select = new Select(driver.findElement(By.id("lineSelect")));
//to select drop down value: 021 : ΠΛΑΤΕΙΑ ΚΑΝΙΓΓΟΣ - ΓΚΥΖH (ΚΥΚΛΙΚΗ)
select.selectByValue("1151_54_9");
