jSoup to check if a span class exists - java

I have a HTML with the following format
<article class="cik" id="100">
<a class="ci" href="/abc/1001/STUFF">
<img alt="Micky Mouse" src="/images/1001.jpg" />
<span class="mick vtEnabled"></span>
</a>
<div>
Micky Mouse
<span class="FP">$88.00</span> <span class="SP">$49.90</span>
</div>
</article>
In the above code the tag inside article has a span class="mick vtEnabled" with no lable. I want to check if this span tag with the class name specified is present within the article tag. How do i do that? I tried select("> a[href] > span.mick vtEnabled") and checked the size..it remains 0 for all the article tags irrespective if its set or not. any inputs?

Element span = doc.select("article.cik > a.ci > span.mick.vtEnabled").first();
if(span != null){
System.out.println("Exist!!");
}
else {
System.out.println("No Span :(");
}

This
Elements divs = doc.select("article > a[href] > span[class=mick vtEnabled]");
selects the div with the two classes.

Iterate <div> inside <ul> tag Java - Jsoup

I'm trying to get all <div> inside a <ul> tag using jsoup.
This is the HTML
<html>
<head>
<title>Try jsoup</title>
</head>
<body>
<ul class="product__listing product__grid">
<div class="product-item">
<div class="content-thumb_gridpage">
<a class="thumb" href="index1.html" title="Tittle 1">
</div>
</div>
<div class="product-item">
<div class="content-thumb_gridpage">
<a class="thumb" href="index2.html" title="Tittle 2">
</div>
</div>
<div class="product-item">
<div class="content-thumb_gridpage">
<a class="thumb" href="index3.html" title="Tittle 3">
</div>
</div>
</ul>
</body>
</html>
What I'm trying to iterate is all <div class="product-item"> so then I can add to a list all <a class="thumb"> properties
List-product-details
[0] href="index1.html" title="Tittle 1"
[1] href="index2.html" title="Tittle 2"
[2] href="index3.html" title="Tittle 3"
Note that there can be 'N' product-item div
Here is What I got so far:
Elements productList = sneakerList.select("ul.product__listing product__grid");
Elements product = productList.select("ul.product-item");
for (int i = 0; i < product.size(); i++) {
Elements productInfo = product.get(i).select("div.product-item").select("div.content-thumb_gridpage").select("a.thumb");
System.out.format("%s %s %s\n", productInfo.attr("title"), productInfo.attr("href"), productInfo.text());
}
Did you try debugging line by line and checking at which line your code doesn't do what you expect?
I see two mistakes.
The first selector "ul.product__listing product__grid" contains a space. Now it means: find element ul with class product__listing and inside search for element <product__grid> </product__grid>. You probably meant: select element ul having class product__listing and having class product__grid. You have to use dot . before second class name and remove space to look at the same level. So correct selector will be: "ul.product__listing.product__grid".
Second selector you're using is "ul.product-item". It will return empty result. That's because you're already inside ul and you're searching for another ul. Selector should be relative to where you are so using only ".product-item" will be enough.
And now I get the ouput:
Tittle 1 index1.html
Tittle 2 index2.html
Tittle 3 index3.html

How to save Element from Jsoup to database

I use Jsoup get all data from website and save element if match some content when i get. I want when we get element. If it match some thing character , I save element from database(MYSQL,Postgress...). I code look like :
Connection conn = Jsoup.connect("https://viblo.asia");
Document doc = conn.userAgent("Mozilla").get();
Elements elements = doc.getElementsByClass("post-feed").get(0).children();
Elements list = new Elements();
Elements strings = new Elements();
for (Element element : elements) {
if (element.hasClass("post-feed-item")) {
list.add(element);
Element e = element.children().get(1).children().get(1).children().get(0);
if (e.text().matches("^.*?(Docker|docker|DOCKER).*$")) {
strings.add(e);
//save to element to DB
}
}
}
for (Element page : elements) {
if (links.add(URL)) {
//Remove the comment from the line below if you want to see it running on your editor
System.out.println(URL);
}
getPageLinks(page.attr("abs:href"));
}
I want if title from element contain : "Docker" it save my element to Database. But in element, It contain div and some thing link url, img , content. How to i save it to database. What if I want to save each element in a field in a database that is feasible? If not I can convert element to html and save it? Please help.
Example html i want save data base:
<div class="post-feed-item">

First, modify your logic for fetching post-feed-item like this-
Connection conn = Jsoup.connect("https://viblo.asia");
Document doc = conn.userAgent("Mozilla").get();
Elements elements = doc.getElementsByClass("post-feed-item"); //This will get the whole element.
for (Element element : elements) {
String postFeeds = "";
if (element.toString().contains("docker")) {
postFeeds = postFeeds.concat(element.toString());
//save postFeeds to DB
}
}
Extra
/**
* Your parsed element may contain single quote (').
* This will cause error while persisting.
* to avoid this you need to escape single quote (')
* with double single quote ('')
*/
if (element.toString().contains("docker")) {
postFeeds = postFeeds.concat(element.toString().replaceAll("'", "''"));
//save postFeeds to DB
}
Second, What if I want to save each element in a field in a database that is feasible?
You don't need separate columns to store each element at the database. However you can save but the feasibility depends on your use case. If you just want to store the post-feed-items only for writing it back to your web page then it is not feasible.
Third, How can I convert element to html and save?
You don't need to convert the element to html but you need to convert the element to String if you want to save it the database.
All you need is a column type of BLOB data type (you can also save it as VARCHAR but BLOB is safer).
Update
How can I traverse all pages?
By looking at the source code of that page I found this is how you can get the total page number -
Elements pagination = doc.getElementsByAttributeValueMatching("href", "page=\\d");
int totalPageNo = Integer.parseInt(pagination.get(pagination.size() - 2).text());
then loop through each page.
for(int page = 1; page <= totalPageNo; page++) {
Connection conn = Jsoup.connect("https://viblo.asia/?page=" + page);
//rest of your code
}
I properly know what's your mean.Here are some views:First you should clearify what`s your search for and make fields of tables in database. Such as according your ideas, you can make a table_docker table in db and there are field_id,field_content,field_start_time,field_links and so on in it. Second you should code some utils of classes such as JsoupUtils which is get HTML and parse it , HtmlUtils which is used to handle the html remarks and download these pictures,DBUtils which is used to connect db and save data,POIUtils which is used to show your data,DataUtils which is used to handle your data by your ways.

How to get input value by using class?

I am using the code below
WebElement inputele = driver.findElement(By.className("class_name"));
String inputeleval = inputele.getAttribute("value");
System.out.println(inputeleval);
but the value is empty. The HTML is below.
<div id="main">
<div id="hiddenresult">
<div class="tech-blog-list">
<label for="Question">1st Question</label>
<input id="txt60" class="form-control" type="text" value="sddf sd sdfsdf sdf sdfsdf sdfsdfsd fsd" />
</div>
</div>
<div class="pagination_main pull-left">
<div id="Pagination">
<div class="pagination">
<a class="previous" onclick="PreviousBtnClickEvent();" href="javascript:void(0)">Previous</a>
<a id="pg59" class="ep" onclick="PaginationBtnClickEvent(this);" href="javascript:void(0)" name="Textbox">1</a>
<a id="pg41" class="ep" onclick="PaginationBtnClickEvent(this);" href="javascript:void(0)" name="Textbox">2</a>
<a id="pg40" class="ep" onclick="PaginationBtnClickEvent(this);" href="javascript:void(0)" name="Textarea">3</a>
<a id="pg60" class="ep current" onclick="PaginationBtnClickEvent(this);" href="javascript:void(0)" name="Textbox">4</a>
</div>
</div>
</div>
</div>
Try using WebDriverWait to wait until element fully loaded on page and visible as below :-
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement inputele= wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("class_name")));
String inputeleval = inputele.getAttribute("value");
System.out.println(inputeleval);
Note :-By.className("class_name") will give that element which class attribute equal to class_name. Make sure which element you want to locate is unique element with class attribute equal to class_name otherwise wise it will give first element with condition true.
Hope it will work..:)
Looks like your code is pretty close but you have the wrong class name? In your code above, you had "class_name" instead of "form-control". I'm assuming that was some sample code and not the actual code you are using? There is only one INPUT in the HTML and the code below should work. It also has an ID so that should be more specific in case there are more than one INPUTs on the page.
WebElement inputele= driver.findElement(By.className("form-control"));
String inputeleval = inputele.getAttribute("value");
System.out.println(inputeleval);

How to find same element from item grid using loop in java selenium?

I am trying to find button add to cart is present or not using loop from all item box from following code
<div class="page-body">
<div class="product-selectors">
<div class="product-filters-wrapper">
<div class="product-grid">
<div class="item-box">
<div class="item-box">
<div class="item-box">
<div class="item-box">
</div>
in each item box folowing code
<div class="item-box">
<div class="product-item" data-productid="20">
<div class="picture">
<div class="details">
<h2 class="product-title">
<div class="product-rating-box" title="1 review(s)">
<div class="description"> 12x optical zoom; SuperRange Optical Image Stabilizer </div>
<div class="add-info">
<div class="prices">
<div class="buttons">
<input class="button-2 product-box-add-to-cart-button" type="button" onclick="AjaxCart.addproducttocart_catalog('/addproducttocart/catalog/20/1/1 ');return false;" value="Add to cart">
</div>
</div>
</div>
</div>
</div>
I need to find that all itembox have add to cart button present or not using loop. if anyone can help please
I suggest to avoid looping if not necessary. You do not need to do the loop to find out unless there is an explicit need of doing so. You can find the count of Add to cart button and compare with a known value
By byCss = By.cssSelector(".item-box>div input[value='Add to cart']");
int cartCount = driver.findElements(byCss).size();
if (cartCount != 4){
//fail the test
}
If you exactly one to looping and check if the input button exist or not.
By itemBoxes = By.className("item-box");
By button = By.cssSelector("[type='button'][value='Add to cart']");
List<WebElement> webElementList = driver.findElements(itemBoxes);
for (WebElement element: webElementList){
//simply taking size if exist it will return 1
if (element.findElements(button).size() != 1){
//fail
}
}
you can use searching by xpath inside of the loop.
Something like
".//input[#value='Add to cart'][1]"
".//input[#value='Add to cart'][2]"
".//input[#value='Add to cart'][3]"
etc
not sure that this xpath is correct, but generally it will work for you, bro.
Or something like this:
string xpath=".//input[#value='Add to cart']";
var AddToCartBtnsList = driver.findElements(By.Xpath(xpath));
foreach(IWebElement button in AddToCartBtnsList )
{
button.click();
}

How do I correctly parse data using JSoup (java)

I want to parse the data out of this HTML (CompanyName, Location, jobDescription,...) using JSoup (java). I get stuck when trying to iterate the joblistings
The extract from the HTML is one of many "JOBLISTING" divs which I want to iterate and extract the Data out of it. I just can't handle how to iterate the specific div objects. Sorry for this noob question, but maybe someone can help me who already knows which function to use. Select?

Thank you!
So you got your Jsoup document right? Than it seems pretty easy if the css class joblisting does not appear anywhere else.
Document document = Jsoup.parse(new File("d:/bla.html"), "utf-8");
Elements elements = document.select(".joblisting");
for (Element element : elements) {
Elements jobTitleElement = element.select(".job_title span");
Elements companyNameElement = element.select(".company_name spanspan[itemprop=name]");
String companyName = companyNameElement.text();
String jobTitle = jobTitleElement.text();
System.out.println(companyName);
System.out.println(jobTitle);
}
I don't know why the attribute [itemprop*=\"name\"] selector does not find the span (Further reading: http://jsoup.org/cookbook/extracting-data/selector-syntax )
Got it: span[itemprop=name] without any quotes or escapes. Other attributes or values also should work to get a more specific selection.
