Setting a merge code into a variable

Aspose.Words Product Family
1

Hi
We use Aspose.Words to merge data into variables such as Variable.Text1
We are now trying to set Aspose variables with the values of our variables. ie.,
Say Variable.Text1 == Comments
We then want to set the Aspose variable S to equal Comments by using this code
<<var [s = “Variable.Text1”]>>
s = <<[s]>>

The problem we are having is that our Variable.Text1 is not merging the value and hence we are getting;
s = Variable.Text1
instead of
s = Comments

Can anyone help with this ?

We suggest you please read the following article.
Using Variables

Please use the following template syntax. We have attached the input and output documents with this post for your kind reference. Docs.zip (20.1 KB)

<<var [s =sender.Name]>><<[s]>>

Please check the following code example that uses the above template syntax.

Document doc = new Document(MyDir + "input.docx");
ReportingEngine engine = new ReportingEngine();
                
Sender sender = new Sender { Name = "LINQ Reporting Engine", Message = "Hello World" };
engine.BuildReport(doc, sender, "sender"); 
                    
doc.Save(MyDir + "19.6.docx");

public class Sender
{
    public String Name { get; set; }
    public String Message { get; set; }
    public String Hyperlink { get; set; }
}

Thanks Tahir. That code is the code we first tried…ie., our variable = Variable.doc
And we have this code in our document
<<var [s=Variable.Text1]>>
s = <<[s]>>
But we get this output in our document
s == Variable.Text1

Based on this you can see that the Variable.Text1 is NOT merging in its own value

Hi Tahir, we have managed to get this working now ONLY when we set the variable as a number. If we set the variable as text we get errors. Can I ask a couple of more questions…

How can we use an <> statement to check if a variable is Null or not… I am trying

<<if [s != “”]>>
Correct
<>
Incorrect
<>

But we are getting an error on the !=

So how can we check if the variable is NULL or not.
Thanks

The code example shared in my previous post works for text variable.
