I am getting request attribute on a JSP page like = ArrayList arr= [a,b,c[e,f,g[j,k,l]]]. The list can be long. How should I show it in such a way a,b,c is parent of e,f,g is parent of j,k,l?
I want something like this or better
<tr onclick=showchild()>
<td> a </td> <td> b </td> <td> c </td>
</tr>
When I click on above tr its child i.e, below tr should be shown.
< tr onclick=showchild()>
<td> e </td <td> f </td> <td> g </td>
</tr>

I'm doing a laundry system where the same timeslots repeat each day, i would like the timeslots to have different ID's to cross reference with the database, is it possible to do this without declaring a new button with new ID each time?
return (
<table id="table">
<thead>{renderTableHeader()}</thead>
<tbody>
<tr>
<td>
<button id="1">07:00-08:30</button>
</td>
<td>
<button id="2">07:00-08:30</button> // this need to be repeated 7 times
</td>
<td>
<button id="3">07:00-08:30</button>
</td>
</tr>
<tr>
<td>
<button id='8'>08:30-10:00</button> //new row whith same functionality
</td>
</tr>
</tbody>
</table>
);
I have similiar structure to this:
<table class="superclass">
<tr>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
</td>
<td>
</td>
</tr>
</table>
<table cellspacing="0">
<tr>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
</td>
<td>
</td>
</tr>
</table>
This is how I get the first table with class:
HtmlNode firstTable = document.DocumentNode.SelectSingleNode("//table[#class=\"superclass\"]");
Then I read the data. However I don't know how to get straight to the another table and read that data too. Any ideas?
I'd rather avoid counting which table it is and then using index to that table.
There is XPath following-sibling axis which allows you to get element following current context element at the same level :
HtmlNode firstTable = document.DocumentNode.SelectSingleNode("//table[#class=\"superclass\"]");
HtmlNode nextTable = firstTable.SelectSingleNode("following-sibling::table");
If you want to access multiple nodes, you can consider SelectNodes(xpath) method over SelectSingleNode(xpath) method.
I'll provide a sample code here for reference, it may not work towards your need.
var tables = htmlDocument.DocumentNode.SelectNodes("//table");
foreach (HtmlNode table in tables)
{
if (table.GetAttributeValue("class", "").Contains("superclass"))
{
//this is the table of class="superclass"
}
else
{
//this is the other table.
}
}
So what im trying to do here is to write a simple html table to a xlsx (excel) file using epplus. The code ive got this far is
controller:
public void saveToExcel(string tbl)
{
using (ExcelPackage p = new ExcelPackage())
{
p.Workbook.Worksheets.Add("demo");
ExcelWorksheet ws = p.Workbook.Worksheets[1];
ws.Name = "Demo";
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment; filename=ExcelDemo.xlsx");
Response.BinaryWrite(p.GetAsByteArray());
}
}
now this creates a empty workbook. And all I want to do right now is to write this table I have in my
View:
<Table id="tbl" name="tbl">
<tr>
<td>
Title 1
</td>
<td >
Title 1
</td>
<td>
Title 1
</td>
</tr>
<tr>
<td >
Row 1
</td>
<td>
Row 1
</td>
<td>
Row 1
</td>
</tr>
<tr>
<td >
Row 2
</td>
<td>
Row 2
</td>
<td>
Row 2
</td>
</tr>
<tr>
<td >
Row 2
</td>
<td>
Row 2
</td>
<td>
Row 2
</td>
</tr>
</table>
#Html.ActionLink("saveToExcel", "saveToExcel")
to the workbook. But I just dont know how and where to start.
Thankful for any pointers in the right direction.
I Guess:
First of all you have to convert your HTML-table to a .NET Datatable
This can be found here Convert Table
Next you use this code (considering your created datatable is called 'data' :
Dim attachment As String = "attachment; filename=MyExcelPage.xlsx"
Dim epackage As ExcelPackage = New ExcelPackage
Dim excel As ExcelWorksheet = epackage.Workbook.Worksheets.Add("ExcelTabName")
excel.Cells("A1").LoadFromDataTable(data, True)
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.ClearHeaders()
HttpContext.Current.Response.ClearContent()
HttpContext.Current.Response.AddHeader("content-disposition", attachment)
HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
HttpContext.Current.Response.BinaryWrite(epackage.GetAsByteArray())
HttpContext.Current.Response.End()
epackage.Dispose()
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 ;
For the following html:
<tr>
<td class="first">AUD</td>
<td> 0.00 </td>
<td> 1,305.01 </td>
<td> 1,305.01 </td>
<td> -65.20 </td>
<td> 0.00 </td>
<td> 0.00 </td>
<td> 1,239.81 </td>
<td class="fx-rate"> 0.98542 </td>
</tr>
I am trying to grab the value for the fx-rate, given the type of current. For example, the function would be something like get_fx_rate(currency). This is the XPATH expression I have so far, but it results in an empty element, []. What am I doing wrong here and what would be the correct expression?
"//td[#class='first']/text()[normalize-space()='AUD']/parent::td[#class='fx-rate']"
Use this:
//td[#class = 'first' and normalize-space() = 'AUD']/parent::tr/td[#class = 'fx-rate']
or clearer:
//tr[td[#class="first1" and normalize-space()="AUD"]]/td[#class="fx-rate"]
This is the way I managed to solve it, using partial xpaths:
### get all the elements via xpath
currencies = driver.find_elements_by_xpath("//td[#class='first']")
fx_rates = driver.find_elements_by_xpath("//td[#class='fx-rate']")
### build a list and zip it to get the k,v pairs
fx_values = [fx.text for fx in fx_rates if fx.text]
currency_text = [currency.text for currency in currencies if currency.text]
zip(currency_text,fx_values)[1:]
