I'm using Blade to fill some tables with content but in some cases a table might end up empty when there is nothing to fill.
Here is part of the php / blade template:
<table class="table">
#isset ($content->client)
<tr>
<td>
Client:
</td>
<td class="text-right">
{{ $content->client }}
</td>
</tr>
#endisset
#isset ($content->published)
<tr>
<td>
Published:
</td>
<td class="text-right">
{{ $content->published }}
</td>
</tr>
#endisset
</table>
In case $content->client and $content->published are not set the result is something like:
<table class="table">
</table>
Is there a simple css way to remove the table entirely in these cases?
I'm familiar with the :empty selector but aparently that doesn't work if there are whitespaces in the tag :(
I would suggest not printing the table if either of the variables are empty.
<?php
if( isset($content->client) || isset($content->published))
{
// echo table
}
?>
Did you try :blank? It also selects whitespace while :empty does not.

I have a complex html structure with lot of tables and divs.. and also the structure might change. How to find xpath by skipping the elements in between.
for example :
<table>
<tr>
<td>
<span>First Name</span>
</td>
<td>
<div>
<table>
<tbody>
<tr>
<td>
<div>
<table>
<tbody>
<tr>
<td>
<img src="1401-2ATd8" alt="" align="middle">
</td>
<td><span><input atabindex="2" id=
"MainLimitLimit" type="text"></span></td>
</tr>
</tbody>
</table>
</div>
</td>
</tr>
</tbody>
</table>
</div>
</td>
</tr>
</table>
I have to get the input element with respect to the "First Name" span
eg :
By.xpath("//span[contains(text(), 'First Name')]/../../td[2]/div/table/tbody/tr/td/table/tbody/tr/td[2]/input")
but.. can I skip the between htmls and directly access the input element.. something like?
By.xpath("//span[contains(text(), 'First Name')]/../../td[2]//input[contains#id,'MainLimitLimit')]")
You can try this Xpath :
//td[contains(span,'First Name')]/following-sibling::td[1]//input[contains(#id, 'MainLimitLimit')]
Explanation :
select <td><span>First Name</span></td> element :
//td[contains(span,'First Name')]
then get <td> element next to above <td> element :
/following-sibling::td[1]
then get <input> element within <td> element selected in the 2nd step above :
//input[contains(#id, 'MainLimitLimit')]
You can use // which means at any level
By.xpath("//span[contains(text(), 'First Name')]//td[2]/input[contains#id,'MainLimitLimit')]")
you can use the "First Name" span as a predicate. Try the code below
//td[preceding-sibling::td[span[contains(text(), 'First Name')]]]//input[contains(#id,'MainLimitLimit')]
I`m using Scrapy Python to try to grep data from the site.
How I can grep this structure with Xpath?
<div class="foo">
<h3>Need this text_1</h3>
<table class="thesamename">
<tbody>
<tr>
<td class="tmp_year">
45767
</td>
<td class="tmp_outcome">
<b>Win_1</b><br>
<span class="tmp_category">TEST_1</span>
</td>
</tr>
<tr>
<td class="tmp_year">
1232004
</td>
<td class="tmp_outcome">
<b>Win_2</b><br>
<span class="tmp_category">TEST_2</span>
</td>
</tr>
<tr>
<td class="tmp_year">
122004
</td>
<td class="tmp_outcome">
<b>Win_3</b><br>
<span class="tmp_category">TEST_3</span>
</td>
</tr>
</tbody>
<h3>Need this text_2</h3>
<table class="thesamename">
<tbody>
<td class="tmp_year">
234
</td>
<td class="tmp_outcome">

<span class="tmp_category">TEST_E</span>
</td>
</tr>
<tr>
<td class="tmp_year">
3476
</td>
<td class="tmp_outcome">
<b>Win_C</b><br>
<span class="tmp_category">TEST_C</span>
</td>
</tr>
</tbody>
<h3>Need this text_3</h3>
<table class="thesamename">
<tbody>
<tr>
<td class="tmp_year">
85567
</td>
<td class="tmp_outcome">
<b>Win_T</b><br>
<span class="tmp_category">TEST_T</span>
</td>
</tr>
<tr>
<td class="tmp_year">
435656
</td>
<td class="tmp_outcome">
<b>Win_A</b><br>
<span class="tmp_category">TEST_A</span>
</td>
</tr>
<tr>
<td class="tmp_year">
980
</td>
<td class="tmp_outcome">
<b>Win_Z</b><br>
<span class="tmp_category">TEST_Z</span>
</td>
</tr>
</tbody>
I would like to have output with this structure:
"Section": {
Need this text_1 :
[45767 : Win_1 : TEST_1]
[1232004 : Win_2 : TEST_2]
[122004: Win_3 : TEST_3]
,
Need this text_2:
[234 : Win_E : TEST_E]
[3476 : Win_C : TEST_C]
,
Need this text_3:
[85567 : Win_T : TEST_T]
[435656 : Win_A : TEST_A]
[980: Win_Z : TEST_Z]
}
How can I create the proper xpath select to take this structure?
I can take separately all "h3" , all "a" then all tags with class but how I can match?
GREP YOU SAY?! LOL Well, You would be entirely wron to name it so but for the sake ofkeeping the jargon cleanfor understanding your just parsing/extracting.... So new to scrapy? or web dev sideof things? No matter... Theres no way I couldexpect to teach you in one answer here how to xpth/regex like a pro... only wayis for you to keep at but I throw in my input.
First of all, xpath is amazingly usefull wen it comes to websites that are necessarily build to stadard, which doesnt make them bad per say but in the html snipet you gave... its structured all right soo.. Id recommend css extract .. THESE ARE THE VALUES...
year = response.css('td.tmp_year a::text').extract()
outcome = response.css('td.tmp_outcome b::text').extract()
category= response.css('span.tmp_category::text').extract()
PRO-TIP: For what ever case you deem it neccesary, you can save a web page asan HTML file and use scrapy shell by referencing the direct file path to it... So I save you html snippet to a file on my desktop then ran...
scrapy shell file:///home/scriptso/Desktop/letsGREPlol.html
ANYWAYS... as far as xpath... since you asked lol... cake. lets compare the xpath with the cssand tell me you can see... it? lol
response.css('td.tmp_outcome b::text').extract()
so is a td tag....and the class name is tmp_outcome, thn the next node is a bold tag... of which where the text is thusly declaring it as text with the ::text
response.xpath('//td[#class="tmp_outcome"]/b/text()').extract()
So xpath is basically saying we star with a patter inthe entire site of the td tag... and class= tmp_outcome, then the bold, then in xpath to declare type /text() is for text.... /#href is for.. yeah you guessedit
I have a question about XPath and the nodeset repeater (XForms).
As you can see in the following code snippet I want to change an attribute of a specific entry of a list and additionally an attribute in the following entry in the nodeset with a trigger.
The first <xf:action> works fine but the second does not. What I want here is to leave the current nodeset of the processinstance, go to the following one and change the attribute state here. How do I realize that with XPath?
<div>
<xf:model>
<xf:instance xmlns="" id="template">
<project id="">
<name/>
...
<processinstance>
<name>
<state>
</processinstance>
</project>
</xf:instance>
</xf:model>
....
<!-- Process repeat table -->
<div>
<table class="table table-hover">
<thead>
<th width="50%">Processname</th>
<th width="50%">State</th>
<th width="50%">Action</th>
</thead>
<tbody id="process-repeat" xf:repeat-nodeset="//project[index('project-repeat')]/processinstance">
<tr>
<td>
<xf:output ref="name"/>
</td>
<td>
<xf:output ref="state"/>
</td>
<td>
<xf:group ref=".[state eq 'in processing']">
<xf:trigger appearance="minimal">
<xf:label>finish process</xf:label>
<xf:action>
<xf:setvalue ref="state">finished</xf:setvalue>
</xf:action>
<!-- THE FOLLOWING DOES NOT WORK AS I WANT! -->
<xf:action>
<xf:setvalue ref="//project[index('project-repeat')]/processinstance[index(process-repeat)+1]">in process</xf:setvalue>
</xf:action>
</xf:trigger>
</xf:group>
</td>
</tr>
</tbody>
</table>
</div>
</div>

One thing is that you have a typo:
index(process-repeat)
vs.
index('process-repeat')
In addition, the index() function represents the currently selected, in the UI, repeat iteration. It does not represent the current iteration being evaluated in XPath.
The bottom line is that you cannot use index('process-repeat') to identify the current repeat iteration. It is a common misunderstanding of the index() function.
Some implementations have functions to identify the current repeat iteration. I assume you are using BetterFORM, and I don't know if it has such a function. With Orbeon Forms you could write:
//project[index('project-repeat')]/processinstance[xxf:repeat-position()]
Or better, if betterFORM supports variables, you could use that to avoid repeating yourself with:
<tbody id="process-repeat" xf:repeat-nodeset="//project[index('project-repeat')]/processinstance">
<xf:var name="current-process" value="."/>
<tr>
<td>
<xf:output ref="name"/>
</td>
<td>
<xf:output ref="state"/>
</td>
<td>
<xf:group ref=".[state eq 'in processing']">
<xf:trigger appearance="minimal">
<xf:label>finish process</xf:label>
<xf:action>
<xf:setvalue ref="state">finished</xf:setvalue>
</xf:action>
<xf:action>
<xf:setvalue ref="$current-process">in process</xf:setvalue>
</xf:action>
</xf:trigger>
</xf:group>

Im trying to render a HTML Table based on a dictionary that I get..The dictionary has 3 items..When I loop through for loop the 1st item is recognized part of the table..The 2nd and 3rd row is not recognized part of the table..
What could the problem?
<html>
<head>
</head>
<body>
<table border="1">
<tr>
<col width="100">
<col width="100">
<col width="100">
<col width="100">
<th>NAME</th>
<th>FEEDBACK</th>
<th>RATING</th>
<th>DATE</th>
</tr>
%for row in feedbacks:
<tr>
<td> {{ row['name'] }} </td>
<td> {{ row['feedback'] }} </td>
<td> {{ row['rating'] }} </td>
<td> {{ row['date'] }} </td>
</tr>
</table>
</body>
</html>
I am not familiar with Bottle, but is seems that you should end your %for loop.
Maybe something along the lines of %end
edit: I am surprised it would not give you some sort of template error though. That is how Flask and Django work. You labelled your post as Django, but I am pretty sure this is no django.
