How to embed HTML in an expression rule

Hi Saurabh.

I don't think there is any direct way to render HTML on Appian. 

Then how can I achieve this . Let me know

Can you paste that HTML here so I can take a look?

a!localVariables(
local!data:rule!T_createDictionary(final: null),
local!titles:{"Name","Age"},
local!startTable:"<table>",
local!closeTable:"</table>",
local!startRowtitle:"<td>",
local!closeRowtitle:"</td>",
local!startRowitemTitle:"<tr>",
local!closeRowItemTitle:"</tr>",
local!startRow:"<tr>",
local!closeRow:"/tr>",
local!startItemRow:"<td>",
local!closeItemrow:"</td>",
local!output:
{
local!startTable & local!startRow & joinarray(
a!forEach(
items: local!titles,
expression: {
local!startRowtitle & fv!item & local!closeRowtitle
}

),
""
) & local!closeRow & joinarray(
a!forEach(
items: local!data,
expression:
/*items with data*/
local!startRow & local!startItemRow & " " & index(
fv!item,
"name",
null
) & local!closeItemrow

)
)
},

local!output


)

a!localVariables(
local!data:rule!T_createDictionary(final: null),
local!titles:{"Name","Age"},
local!startTable:"<table>",
local!closeTable:"</table>",
local!startRowtitle:"<td>",
local!closeRowtitle:"</td>",
local!startRowitemTitle:"<tr>",
local!closeRowItemTitle:"</tr>",
local!startRow:"<tr>",
local!closeRow:"/tr>",
local!startItemRow:"<td>",
local!closeItemrow:"</td>",
local!output:
{
local!startTable & local!startRow & joinarray(
a!forEach(
items: local!titles,
expression: {
local!startRowtitle & fv!item & local!closeRowtitle
}

),
""
) & local!closeRow & joinarray(
a!forEach(
items: local!data,
expression:
/*items with data*/
local!startRow & local!startItemRow & " " & index(
fv!item,
"name",
null
) & local!closeItemrow

)
)
},

local!output


)

I have to send a message in google chat . i have working Google integration to send message . just I want to create a message with SNO ||  Date || links 

When you already have data in your local variables, then why do you want to convert it in HTML first and then render the HTML on Interface?

As I mentioned above I have to send a message via Google chat . So want it to in a proper format

Hi Saurabh, 

if your requirement is to send the request body in HTML text with only 3 columns and your current expression rule also provides the HTML table.

Here's a code snippet where you can remove some un-necessary variables, hope it helps.

a!localVariables(
  local!data: {
    {
      date: today(),
      link: {
        href: "https://www.google.com",
        value: "Google"
      }
    },
    {
      date: today() - 4,
      link: {
        href: "https://community.appian.com",
        value: "Community"
      }
    },
    {
      date: today() + 3,
      link: { href: "", value: "Appian" }
    }
  },
  joinarray(
    {
      "<table>",
      "<tr><th>S.No.</th><th>Date</th><th>Links</th></tr>",
      a!forEach(
        items: local!data,
        expression: concat(
          "<tr>",
          "<td>" & fv!index & "</td>",
          "<td>" & text(fv!item.date, "mmm dd yyyy") & "</td>",
          "<td> 
          <a href='" & a!defaultValue(fv!item.link.href, "#") & "'>" & fv!item.link.value & "</a>",
          "</td>",
          "</tr>"
        )
      ),
      "</table>"
    },
    char(10)
  )
)

The above code displays as below on a browser

Hi agam , thanks for replying will this grid will work in Google chat . Means I have to send a message in Google chat

Hi Saurabh,

It depends on how the Google API is expecting the request format to be

You can try / check in their documentation
