And we noticed that in the older version of aspose, if the merge field for the ProgramName was empty, the output document removed that line entirely like this:
However in the newer version of aspose, the output document leaves the line where that merge field was:
We were just curious as to if there’s anything we can do to make the document match the old way where the line feed is deleted for that merge field that is no longer there.
To achieve the behavior where empty merge fields result in the removal of the corresponding lines in your document, you can utilize the cleanup options available in Aspose.Words. Specifically, you should set the cleanup options to remove empty paragraphs and unused fields during the mail merge process.
Cause: When performing a mail merge, empty merge fields can leave behind unwanted empty lines in the final document.
Solution: You can resolve this by using the setCleanupOptions method to specify that empty paragraphs and unused fields should be removed.
Next Steps: Implement the following code in your application:
Document doc = new Document("your-template.docx");
doc.getMailMerge().setCleanupOptions(MailMergeCleanupOptions.REMOVE_EMPTY_PARAGRAPHS | MailMergeCleanupOptions.REMOVE_UNUSED_FIELDS);
// Execute the mail merge with your data
String[] fieldNames = { "ProgramName" };
Object[] fieldValues = { null }; // Assuming ProgramName is empty
doc.getMailMerge().execute(fieldNames, fieldValues);
doc.save("output.docx");
By setting the cleanup options as shown, any empty merge fields will not leave behind empty lines in the output document, effectively mimicking the behavior of the older version you mentioned.
