Hi Bob,

Are you writing XSLT or Razor? are you parsing HTML tables from a rich text editor and trying to turn them into fo tables?

Darren, i am using the razor syntax... basically, i need to be able to assign row span based on the <th colspan="4"> attribute - i have a collection of cases... but i am getting somewhat confused.

here is a sample of the markup from the rich text editor...

<table border="0" cellspacing="0" cellpadding="0">
<thead>
<tr>
<th colspan="4">How Much You Pay for a Covered Prescription Drug in
2012</th>
</tr>
</thead>

<tbody>
<tr>
<th>&nbsp;</th>
<th class="ctr" colspan="2">Retail Pharmacy<br />
 (up to a 30-day supply)</th>
<th class="ctr">Medco By Mail<br />
 (up to a 100-day supply)</th>
</tr>

<tr>
<th>&nbsp;</th>
<th>First Three Fills</th>
<th>Each Subsequent Refill</th>
<th>&nbsp;</th>
</tr>

<tr>
<td>Generic</td>
<td>20% ($5 minimum)</td>
<td>35% ($5 minimum)</td>
<td>20% ($10 minimum)</td>
</tr>

<tr>
<td>Formulary</td>
<td>20% ($15 minimum)</td>
<td>35% ($15 minimum)</td>
<td>20% ($30 minimum)</td>
</tr>

<tr>
<td>Non-formulary</td>
<td>20% ($30 minimum)</td>
<td>35% ($30 minimum)</td>
<td>20% ($60 minimum)</td>
</tr>
</tbody>
</table>

and here are my case statements...

case "table":
   <fo:table width="100%" border="1px solid #DAE1E5" margin-bottom="12pt" border-spacing="0" color="#656f74" >
     @ParseRichText(node.ChildNodes)
   </fo:table>
   break;
  
   case "tbody":
   <fo:table-body font-size="10pt">
     @ParseRichText(node.ChildNodes)
   </fo:table-body>
   break;
   case "thead":
<fo:table-header number-rows-spanned="4" border-bottom="1px solid #26363E" background="#FF0000" padding="3pt" font-weight="bold" text-align="center">
<fo:table-row>@ParseRichText(node.ChildNodes)</fo:table-row>
</fo:table-header>
break;
      
   case "tr":
   <fo:table-row>
     @ParseRichText(node.ChildNodes)
   </fo:table-row>
   break;
   case "th":
   
   <fo:table-cell number-rows-spanned="" border-bottom="1px solid #26363E" background="#DAE1E5" padding="3pt" font-weight="bold" text-align="center">
     <fo:block>@ParseRichText(node.ChildNodes)</fo:block>
   </fo:table-cell>
   break;
   case "td":
   <fo:table-cell border="1px solid #DAE1E5" padding="3pt">
     <fo:block>@ParseRichText(node.ChildNodes)</fo:block>
   </fo:table-cell>
   break;

I don't really understand what you are trying to do based on the description above - but if the 4 in <th colspan="4"> is variable and you want to do some output based on the value then you'd need to modify the ParseRichText function to take a second parameter e.g. ParseRichText(node.ChildNodes, 4)

to expand on the above...

the client is creating tables in the rich text editor - they are able to have cells span multiple rows, etc. [see markup above as a generic example]

The challenge comes in when parsing to PDF using the razor examples you have provided. I was able to add case statement to handle the table nodes, etc. but have no idea how to handle a rowspan element on the node to translate that into some xsl:fo syntax to make it work for any tables rendered by the engine.

does that help? I am actually struggling with this aspect on TWO sites right now and imagine it will continue to come up... so the ability to have a solution for table rendering would be great.

thanks,

bob

i get a generic error when adding that to the th case

case "th":
   @{ var rowSpan = node.Attributes["rowspan"].Value }
   <fo:table-cell number-rows-spanned="@rowSpan" border-bottom="1px solid #26363E" background="#DAE1E5" padding="3pt" font-weight="bold" text-align="center">
     <fo:block>@ParseRichText(node.ChildNodes)</fo:block>
   </fo:table-cell>
   break;

what am i missing?

here is what the trace shows...

Error loading MacroEngine script (file: , Type: ''

  at umbraco.macro.renderMacro(Hashtable pageElements, Int32 pageId)

Does a th always have a rowspan? can you look at the temp file mentioned in the error and post line 171?

d:\HostingSpaces\SegalDev\psccunywf.org\wwwroot\App_Data\TEMP\Razor\inline-09096d6234f6338607892e620d0ef855.cshtml

If there isn't a rowspan you'd need to do a null check.

ah, there is not ALWAYS a rowspan... so let me try a null check

grrrr... i hate that i don't know razor :(

how do i write this null statement?

@{var rowSpan = string.IsNullOrEmpty(node.Attributes["rowspan"].Value);}

that is not working???

Untested 'cos i don't have Umbraco installed on this PC but something like:

@{var rowSpan = (node.Attributes["rowspan"] == null ? node.Attributes["rowspan"].Value : 1);}

bob,

try node.Attributes["rowspan"]!=null as I suspect you wont have it at all and therefore it cannot test value.

Regards

Ismail

still get the same error - and the error is on this line...

@{var rowSpan = (node.Attributes["rowspan"] != null ? node.Attributes["rowspan"].Value : 1);}

any more thoughts?

Bit of a shot in the dark, is it possible to use node.HasAttribute("rowspan")?

okay, the issue is something completely different...

this statement even throws an error... why?

@{var rowSpan = 7}

still says an argument is missing?

okay, i did not need braces... i am getting closer... no i am getting this error

Type of conditional expression cannot be determined because there is no implicit conversion between 'string' and 'char'
  at umbraco.macro.renderMacro(Hashtable pageElements, Int32 pageId)

from this  line

var rowSpan = (node.Attributes["colspan"].Value != null ? node.Attributes["colspan"].Value : '2');

Change the '2' to "2" perhaps?

Thanks so much Jason!

what a great community effort on this one... i am slowly learnign more and more each day... and this thread was a huge help!

thanks to all... so... to close the loop, here is what it all looked like in the end...

case "th":
   var rowSpan = node.Attributes["colspan"] != null ? node.Attributes["colspan"].Value : "1";
   
   <fo:table-cell number-columns-spanned="@rowSpan" border-bottom="1px solid #26363E" background="#DAE1E5" padding="3pt" font-weight="bold" text-align="center">
     <fo:block>@ParseRichText(node.ChildNodes)</fo:block>
   </fo:table-cell>
   
   break;

so basically, we are checking for a colspan in the RTE table, if it exists, use the value, if not... set it to 1 - what a cool little app this is ;)

is working on a reply...
