Unwanted Padding in QTextEdit HTML Subset <img> - html

I am trying to insert an image in a table html inside a QTextEdit Subset.
I would like that image to fit perfectly with the table width.
Unfortunately nothing goes smooth with Qt and an annoying padding is left at the right and under the image.
Here is the simplified code (use any image to test), anyone as any idea on how to avoid it?
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import QCoreApplication, QRect, Qt
class Labhtml(QTextEdit):
def __init__(self):
super().__init__()
html= '''
<table border="1" cellspacing="0" cellpadding="0">
<tr>
<td>
<img src="bar.png">
</td>
</tr>
</table>
'''
self.setText(html)
class Example(QScrollArea):
def __init__(self):
super().__init__()
widget = QWidget()
layout = QVBoxLayout(widget)
layout.setAlignment(Qt.AlignTop)
layout.addWidget(Labhtml())
self.setWidget(widget)
self.setWidgetResizable(True)
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
Qt is full of these glitches when it comes to subset I am nearly going to give up.

The problem is caused by the whitespace you've added within the td tag. So one way to fix the problem is like this:
<table border="1" cellspacing="0" cellpadding="0">
<tr>
<td><img src="image.png"></td>
</tr>
</table>
Alternatively, use fixed dimensions that are smaller than the image:
<table border="1" cellspacing="0" cellpadding="0">
<tr>
<td width="0" height="0">
<img src="image.png">
</td>
</tr>
</table>

Beautiful soup finding the first sibling of a known object with a known attribute

I have the following code to select a certain cell in a table element:
tag = soup.find_all('td', attrs={'class': 'I'})
as shown in the attached image 1, I would like to somehow be able to find its first sibling within the same class "even_row". Ideally, the selection would output only the contents of data-seconds, in this case "58". Not every "even_row" class has a element with class I, and some have more than one, so I need to get the value data-seconds only for the "even_row" classes that have the element with class "I"
Any help would be appreciated as I've been banging my head on the wall looking through documentation to no avail.
html look like :
<tr class='even_row'>
<td class='row_labels' data-seconds="58">
<div class='celldiv slots1'></div>
</td>
<td class='new'>...</td>
<td class='I'>...</td>
<td class='new'>...</td>
<td class='new'>...</td>
One way to get around that issue is to pass True
from bs4 import BeautifulSoup
html = """
<tr class='even_row'>
<td class='row_labels' data-seconds="58">
<div class='celldiv slots1'></div>
</td>
<td class='new'>...</td>
<td class='I'>...</td>
<td class='new'>...</td>
<td class='new'>...</td>
</tr>
<tr class='even_row'>
<td class='row_labels' >
<div class='celldiv slots1'></div>
</td>
<td class='new'>...</td>
<td class='I'>...</td>
<td class='new'>...</td>
<td class='new'>...</td>
</tr>
"""
soup = BeautifulSoup(html,'html.parser')
even_rows = soup.find_all('tr', attrs={'class': 'even_row'})
for row in even_rows:
tag = row.find("td", {"data-seconds" : True})
if tag is not None:
print(tag.get('data-seconds'))
Output :
58
another way to do it is using regular expressions
import re
tds = [tag.get('data-seconds') for tag in soup.findAll("td", {"data-seconds" : re.compile(r".*")})]
print(tds)
Output :
['58']
Cannot test properly without the html but sounds like with bs4 4.7.1+ you can use :has to satisfy your requirements for .even_row:has(.I) i.e. parent with class even_row, having child with class I, and then add in [data-seconds] to cater for all child data-seconds attribute values
print([i['data-seconds'] for i in soup.select('.even_row:has(.I) [data-seconds]')])

How to check if a text exist in IE webpage under div class/TR/TD Class?

I have tried finding a solution to my problem for few days already - somehow I just don't manage to find a working solution.
Unfortunately I cannot give the URL for the webpage that I have as it would require a login and password - which I cannot share.
I have the VBA code already doing me everything, login into the webpage - proving the proper information inside the page and clicking validate button. But the problem is that I should then see if the below text appears:
ENQUADRAMENTO EM VIGOR - if yes, I will continue slightly differently the process and if not then differently.
Now below is the code from the webpage:
<tr>
<td>
<table cellpadding="4" border="0" width="100%">
<tbody><tr>
<td class="fieldTitleBold" style="width=30%">Enquadramento em IVA</td>
<td class="fieldValue" colspan="3">NORMAL TRIMESTRAL</td>
</tr>
<tr>
<td style="width=10%" class="fieldTitleBold">Situação</td>
<td class="fieldValue" colspan="3">ENQUADRAMENTO EM VIGOR</td>
</tr>
</tbody></table>
</td>
</tr>
I have tried many different ways and the latest I tried is with byclassname (this worked for me in a different website for similar purpose) but doesn't work here for some reason:
Set doc = ie.document
Set htmTable = doc.getElementsByClassName("ENQUADRAMENTO EM VIGOR")(0)
If Not htmTable Is Nothing Then
'continue depending if the text was found or not in different ways
ENQUADRAMENTO EM VIGOR is the .innerText value not the class name. The class value is fieldValue and is associated with a td (table cell) element.
This is pretty easy if it only occurs once. Use Instr to see if present in page html
If Instr(ie.document.body.innerHTML,"ENQUADRAMENTO EM VIGOR") > 0 Then
Otherwise, you can gather a nodeList of td elements with that class name and loop testing the .innerText
Dim classes As Object, i As Long
Set classes = ie.document.querySelectorAll("td.fieldValue")
For i = 0 To classes.Length - 1
If classes.item(i).innerText = "ENQUADRAMENTO EM VIGOR" Then
'do something
'Exit For ....
End If
End Sub
$(document).ready(function() {
var lenfV = document.querySelectorAll(".fieldValue");
for(let i=0;i<lenfV.length;i++) {
if(lenfV[i].innerHTML == "ENQUADRAMENTO EM VIGOR") {
console.log("is there");
}
//else {console.log(213423);}
}
});

<p> I think, The below option will help you</p>
<table>
<tr>
<td>

<td class="fieldTitleBold" style="width=30%">Enquadramento em IVA</td>
<td class="fieldValue" colspan="3">NORMAL TRIMESTRAL</td>

Now How I will set table class in python code like
<table class='calender_tabe'>
Can someone help me to set class of table and other tag using python dominate library?
Using the example syntax from github's documentation
from dominate.tags import *
testTable = table(border = 1)
print testTable
which will return:
<table border="1"></table>
with the print statement. However since you can't use the word "class" to refer to the html attribute (class being a python-reserved word) you have to go about it indirectly:
testTable.set_attribute('class','my_class_name')
Adding the above to the original instance of testTable will result in:
<table border="1" class="my_class_name"></table>

How to get line from table with Jsoup

I have table without any class or id (there are more tables on the page) with this structure:
<table cellpadding="2" cellspacing="2" width="100%">
...
<tr>
<td class="cell_c">...</td>
<td class="cell_c">...</td>
<td class="cell_c">...</td>
<td class="cell">SOME_ID</td>
<td class="cell_c">...</td>
</tr>
...
</table>
I want to get only one row, which contains <td class="cell">SOME_ID</td> and SOME_ID is an argument.
UPD.
Currently i am doing iy in this way:
doc = Jsoup.connect("http://www.bank.gov.ua/control/uk/curmetal/detail/currency?period=daily").get();
Elements rows = doc.select("table tr");
Pattern p = Pattern.compile("^.*(USD|EUR|RUB).*$");
for (Element trow : rows) {
Matcher m = p.matcher(trow.text());
if(m.find()){
System.out.println(m.group());
}
}
But why i need Jsoup if most of work is done by regexp ? To download HTML ?
If you have a generic HTML structure that always is the same, and you want a specific element which has no unique ID or identifier attribute that you can use, you can use the css selector syntax in Jsoup to specify where in the DOM-tree the element you are after is located.
Consider this HTML source:
<html>
<head></head>
<body>
<table cellpadding="2" cellspacing="2" width="100%">
<tbody>
<tr>
<td class="cell">I don't want this one...</td>
<td class="cell">Neither do I want this one...</td>
<td class="cell">Still not the right one..</td>
<td class="cell">BINGO!</td>
<td class="cell">Nothing further...</td>
</tr> ...
</tbody>
</table>
</body>
</html>
We want to select and parse the text from the fourth <td> element.
We specify that we want to select the <td> element that has the index 3 in the DOM-tree, by using td:eq(3). In the same way, we can select all <td> elements before index 3 by using td:lt(3). As you've probably figured out, this is equal and less than.
Without using first() you will get an Elements object, but we only want the first one so we specify that. We could use get(0) instead too.
So, the following code
Element e = doc.select("td:eq(3)").first();
System.out.println("Did I find it? " + e.text());
will output
Did I find it? BINGO!
Some good reading in the Jsoup cookbook!

How to embed links (anchor tag) into HTML context from UIBINDER in gwt

I have a HTML widget in my ui.xml which I am using in Uibinder to populate data as given below:
ui.xml ->
<g:HTML ui:field="operationsDetailTableTemplate" visible="false">
<table class="{style.LAYOUT_STYLE}" width="100%" border="1">
<tr>
<td><img src="images/indent-blue.gif"/></td>
<td>
<table class="{style.DEFAULT_STYLE}">
<thead>
<tr>
<th>OperationUuid</th>
....
</tr>
</thead>
<tbody>
<tr>
<td>%s</td>
...
</tr>
</tbody>
</table>
</td>
</tr>
....
</g:html>
Uibinder.java--->
String htmlText = operationsDetailTableTemplate.getHTML()
.replaceFirst("%s", toSafeString(operation.getOperationUuid()))
....
HTML html = new HTML(htmlText);
operationsDetail.add(html);
The above is done in a for loop for each of the operation retrieved from the database.
My question is how I can embed a hyperlink or an anchor tag on one of the cell (eg. operation id ) for each of the operation set retrieved. I also wish to have a listener attached to it.
P.S. - It does not allow me to have a anchor tag in HTML in ui.xml.
You'd better use the tools in the way they've been designed to be used: use ui:field="foo" on the <td> and #UiField Element foo + foo.setInnerHTML(toSafeString(...)) instead of extracting the HTML, modifying it and reinjecting it elsewhere. You could also use a <g:Anchor> and attach an #UiHandler to handle ClickEvents.
Your way of using UiBinder makes me think of SafeHtmlTemplates, or the new UiRenderer aka UiBinder for Cells: https://developers.google.com/web-toolkit/doc/latest/DevGuideUiBinder#Rendering_HTML_for_Cells
