Hi, i’m doing a word compare with the following documents AsposeTest4.7z (33.2 KB)
This is the code of the test:

public class AsposeTest4 {

	public static void main(String[] args) throws Exception {
		Document doc1 = new Document("C:\\AsposeTest\\" + "LEFT.docx");
		Document doc2 = new Document("C:\\AsposeTest\\" + "RIGHT.docx");

		removeSdt(doc1);
		removeSdt(doc2);
                //COMMENT THESE SAVES FOR A DIFFERENT RESULT
		doc1.save("C:\\AsposeTest\\" + "COMPARE RESULT LR.docx", SaveFormat.DOCX);
		doc2.save("C:\\AsposeTest\\" + "COMPARE RESULT LR2.docx", SaveFormat.DOCX);
		doc1.compare(doc2, "Me",  new Date());

		RevisionCollection revisions = doc1.getRevisions();
		for (int i = 0; i < revisions.getCount(); i++) {
			Revision r = revisions.get(i);
			Node node = r.getParentNode();
			String temp = node.getText();
			System.out.println(temp);
		}
	}

	@SuppressWarnings("unchecked")
	private static void removeSdt(Document doc) {
		for (StructuredDocumentTag sdt : (Iterable<StructuredDocumentTag>)doc.getChildNodes(NodeType.STRUCTURED_DOCUMENT_TAG, true)) {
			try {
				if (sdt.getXmlMapping().isMapped()) {
					sdt.getXmlMapping().delete();
				}
				sdt.removeSelfOnly(); // Removes just this SDT node itself, but keeps the content of it inside the document tree
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
}

If i do the compare without documents save i get this result:

WITH document save i get this result:

The biggest differences are the table headers, are considered revisions without save but not with save.

I’m doing the compare on memory so saving the document in the middle is not a real option for me. What does document.save() do that i could do to get the result without actually performing the save.

Thank you.

@lconde57 Upon doing save operation Aspose.Words performs document validation to make the model valid and clear. Looks like in your case removing structured document tags somehow invalidates the model. You can make an intermediate save operation in memory to force Aspose.Words to perform validation before comparison:

removeSdt(doc1);
removeSdt(doc2);
//COMMENT THESE SAVES FOR A DIFFERENT RESULT
doc1.save(new ByteArrayOutputStream(), SaveFormat.DOCX);
doc2.save(new ByteArrayOutputStream(), SaveFormat.DOCX);
doc1.compare(doc2, "Me",  new Date());
