i need to change quite some html entries in a mysql database. my problem is that some tags need to be replaced while the surrounded code needs to stay the same. in detail: all td-tags in tr-tags with the class "kopf" need to be changed to th-tags (and the addording closing for the tags)
it would not be a problem without the closing tags..
update `tt_content` set `bodytext` = replace(`bodytext`,'<tr class="kopf"><td colspan="2">','<tr><th colspan="2">');
this would work
from what i found the %-sign is used, but how exactly?:
update `tt_content` set `bodytext` = replace(`bodytext`,'<tr class="kopf"><td colspan="2">%</td></tr>','<tr><th colspan="2">%</th></tr>');
i guess this would replace all the code within the old td tags by a %-sign?? how can i achive the needed replacement?
edit: just to clarify things here is a possible entry in the db:
<table class="techDat" > <tbody> <tr class="kopf"> <td colspan="2"> <p><strong>Technical data:</strong></p> </td> </tr> <tr> <td> <p>Operating time depending on battery chargeBetriebszeit je Akkuladung</p> </td> <td> <p>Approx. 4 h</p> </td> </tr> <tr> <td> <p>Maximum volume</p> </td> <td> <p>Approx. 120 dB(A)</p> </td> </tr> <tr> <td> <p>Weight</p> </td> <td> <p>Approx. 59 g</p> </td> </tr> </tbody> </table>
after the mysql replacement it should look like
<table class="techDat" > <tbody> <tr> <th colspan="2"> <p><strong>Technical data:</strong></p> </th> </tr> <tr> <td> <p>Operating time depending on battery chargeBetriebszeit je Akkuladung</p> </td> <td> <p>Approx. 4 h</p> </td> </tr> <tr> <td> <p>Maximum volume</p> </td> <td> <p>Approx. 120 dB(A)</p> </td> </tr> <tr> <td> <p>Weight</p> </td> <td> <p>Approx. 59 g</p> </td> </tr> </tbody> </table>
Try two replaces
update `tt_content` set `bodytext` =
replace(replace(`bodytext`,
'<tr class="kopf"><td colspan="2">','<tr><th colspan="2">'),
'</td></tr>','</th></tr>')
Try updating your records with two queries :
1) for without % sign:
updatett_contentsetbodytext= replace(bodytext,'<tr class="kopf"><td colspan="2">','<tr><th colspan="2">');
2) for % sign
updatett_contentsetbodytext= replace(bodytext,'<tr class="kopf"><td colspan="2">%</td></tr>','<tr><th colspan="2">%</th></tr>')
where instr(bodytext,'%') > 0 ;

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 am newbie.
I have a problem how to convert html table with fpdf.
This is my html code
<html>
<body>
<table border=1 align=center>
<tr>
<tr>
<td> </td>
<td>PO1</td>
<td>PO2</td>
</tr>
<tr>
<td>LO1</td>
<td> "THIS WILL TAKE THE VALUE FROM DATABASE " </td>
<td> "THIS WILL TAKE THE VALUE FROM DATABASE " </td>
</tr>
<tr>
<td>LO2</td>
<td> "THIS WILL TAKE THE VALUE FROM DATABASE " </td>
<td> "THIS WILL TAKE THE VALUE FROM DATABASE " </td>
</tr>
</table>
</body>
</html>
Can anyone tell me how to do it?
please take a look the example at http://www.fpdf.org/en/script/script41.php
Let's assume that we have three tables, tbl_student ,tbl_lesson and tbl_score(student_id, lesson_id, score).
for Activedataprovider, we have:
$query = \app\models\Score::find()
->joinWith('student', false)
->joinWith('lesson', false);
$provider = new \yii\data\ActiveDataProvider([
'query' => $array,
]);
echo GridView::widget([
'dataProvider' => $dataProvider,
]);
So it gives an output with columns : student_id, lesson_id, score:
<table border="1">
<tr>
<td> student_id </td>
<td> lesson_id </td>
<td> score </td>
</tr>
<tr>
<td> 1 </td>
<td> 1 </td>
<td> 99.5 </td>
</tr>
<tr>
<td> 1 </td>
<td> 2 </td>
<td> 54 </td>
</tr>
<tr>
<td> 1 </td>
<td> 3 </td>
<td> 87 </td>
</tr>
<tr>
<td> 2 </td>
<td> 1 </td>
<td> 76 </td>
</tr>
<tr>
<td> 2 </td>
<td> 2 </td>
<td> 84 </td>
</tr>
<tr>
<td> 2 </td>
<td> 3 </td>
<td> 69 </td>
</tr>
</table>
But what I want is to display students in the first COLUMN, and lessons in the first ROW and then display the associated scores in the body of the table:
<table border="1">
<tr>
<td>student_id</td>
<td>lesson_1</td>
<td>lesson_2</td>
<td>lesson_3</td>
</tr>
<tr>
<td>1</td>
<td>99.5</td>
<td>54</td>
<td>87</td>
</tr>
<tr>
<td>2</td>
<td>76</td>
<td>84</td>
<td>69</td>
</tr>
</table>
How can I do that?
Thanks in advance.
I know that I can use Arraydataprovider, but as said in Yii2 data providers guide
Note: Compared to Active Data Provider and SQL Data Provider, array data provider is less efficient because it requires loading all data into the memory.

but I want to do it using Activedataprovider
I have a main table and then insert sub tables each td. Like below The problem is lets say I have:
<table id = "main>
<tr>
<th id = "header1">blah</td>
<th id = "header2">blah</td>
<th id = "header3">blah</td>
</tr>
<tr><td>
<table id = "sub1">
<tr><td headers='header1'>1</td></tr>
</table>
</td>
<td>
<table id = "sub2">
<tr><td headers='header2'>2</td></tr>
</table>
</td>
<td>
<table id = "sub3">
<tr><td headers='header3'>3</td></tr>
</table>
</td>
</tr>
</table>
now if sub1 has only 4 rows in it but sub 2 and 3 each have 100 rows the table keeps putting sub1 table in the middle of the rest of the table. How would i stop it from doing that?
Try this:
<td valign="top">
You have to specify, where to align the content of td
Look in to valign
<td valign='top'>
Updated source
<table id = "main>
<tr>
<th id = "header1">blah</td>
<th id = "header2">blah</td>
<th id = "header3">blah</td>
</tr>
<tr><td valign='top'>
<table id = "sub1">
<tr><td headers='header1'>1</td></tr>
</table>
</td>
<td>
<table id = "sub2">
<tr><td headers='header2'>2</td></tr>
</table>
</td>
<td>
<table id = "sub3">
<tr><td headers='header3'>3</td></tr>
</table>
</td>
</tr>
</table>
If you are increasing/decreasing the no. of rows/cols in your tables, you may need to adust the same through rowspan and colspan properties. Also displaying text at the top of any cell needs valign="top" property
Make the second table row (after the header row) opening tag <tr style="vertical-align:top">. That will work and there is no need for rowspan or colspan.
Please, either look at http://jsfiddle.net/mawg/pL9kd/ or stick the code below into your favourite HTML editor ...
Look to the right of OMG! Item 4 contains a *nested* array. (How) can I get that nested array (xyz) to be 2 columns wide, even if its content doesn't need so much space?
<table border="1" cellpsacing="0" cellpadding="0" style="">
<tr><th style="border-width:1" colspan="3">This is an array</th></tr>
<td colspan="2">
<table border="1">
<tr><td colspan="3">Array</td></tr>
<tr>
<td>item 1</td>
<td>string ( 3 chars)</td>
<td>abc</td>
</tr>
<tr>
<td>0</td>
<td>string ( 25 chars)</td>
<td>item 2 is indexed by zer0</td>
</tr>
<tr>
<td>this equals seven</td>
<td>integer</td>
<td>7</td>
</tr>
<tr>
<td>item 4 is a nested array</td>
<td colspan="2">
<table border="1">
<tr><td colspan="3">Array</td></tr>
<tr>
<td>0</td>
<td>string ( 24 chars)</td>
<td>item 4, offest 0's value</td>
</tr>
<tr>
<td>OMG! Item 4 contains a *nested* array F5</td>
<td colspan="2">
<table border="1">
<tr><td colspan="3">Array</td></tr>
<tr>
<td>xyz</td>
<td>string ( 7 chars)</td>
<td>xyz val</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>item 4, offest 2 is True</td>
<td>boolean</td>
<td>True</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>final item</td>
<td colspan="2">NULL</td>
</tr>
</table>
</td>
</table>
Do you mean like this? http://jsfiddle.net/pL9kd/8/
(Width = 100%)
Check this you can use the width, to set to width='66%' which works since you know there are 3 columns and 2/3 is 66%. Also set the containing table to width='100%' since you are going to need all of the possible space.
From what I could find there is nothing like what your asking (or at least my interpretation of it). Could you not simply create a column width equaling two total columns?
So something like
<td width="40">xyz</td>
I could be way off but that's just my guess. Just curious, what is the implementation for this? I am sure you know css lists and other css elements are much more efficient at styling, correct?
