Aspose.words document merge - remove blank lines

Aspose.Words Product Family

I’m evaluating aspose.words for Java before I commit to purchasing it and i’m testing it for merging the header and footer in a notepaper document into a main document. When I merge the header from the notepaper into the main document, extra blank lines are introduced. I was wondering how I can easily remove these blank lines in the merged document header/footer.

Below is the code im using to merge the notepaper header & footer into the main report document:

								//Loop through headers & footers in notepaper document  
								for(HeaderFooter notepaperHdrFtr : notepaperSection.getHeadersFooters()) {  
									//Check whether current report section contains header/footer of same type in notepaper  
									if(reportSection.getHeadersFooters().getByHeaderFooterType(notepaperHdrFtr.getHeaderFooterType())!=null) {  
										//Add header footer content from notepaper to report  
										for(Node notepaperChild : (Iterable<Node>) notepaperHdrFtr.getChildNodes()) {  
											Node reportChild = report.importNode(notepaperChild, true, ImportFormatMode.KEEP_SOURCE_FORMATTING);	
											reportSection.getHeadersFooters().getByHeaderFooterType(notepaperHdrFtr.getHeaderFooterType()).appendChild(reportChild);  											
										}	  								
									}	  							
									else {  
										Node reportHdrFtr = report.importNode(notepaperHdrFtr, true, ImportFormatMode.KEEP_SOURCE_FORMATTING);  
										reportSection.getHeadersFooters().add(reportHdrFtr);  
									}	  							
								}

I simply want to know how using the library I can identify and remove blank lines in the header & footer, do you have any example code for this? I don’t need specific help for the work im trying to do.

@athavant,

The following code will simply remove all Paragraphs (with no text inside) in Headers Footers of all the Sections in Word document:

Document doc = new Document("E:\\temp\\HeaderFooterHeights.docx");

for (Section sec : doc.getSections()){
    for (HeaderFooter hf : sec.getHeadersFooters()){
        for (Paragraph para : (Iterable<Paragraph>) hf.getChildNodes(NodeType.PARAGRAPH, true)){
            if (para.toString(SaveFormat.TEXT).trim().equals("")){
                para.remove();
            }
        }
    }
}

doc.save("E:\\Temp\\awjava-19.11.docx");

Hope, this helps.

Thanks for this but it hasn’t worked, within each paragraph is it possible to check for blank lines and remove them?
