Remove All Paragraphs in a Word Document in Java
To remove all paragraphs, you need to loop through all sections in a document and then delete all paragraphs in each section using Section.getParagraphs().clear() method. The following are the detailed steps.
- Create a Document instance.
- Load a Word document using Document.loadFromFile() method.
- Traverse through each section of the document and then remove all paragraphs in the section using Section.getParagraphs().clear() method.
- Save the result document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
public class removeAllParagraphs {
public static void main(String[] args) {
//Create a Document instance
Document document = new Document();
//Load a sample document from disk
document.loadFromFile("E:\\Files\\test23.docx");
//Remove paragraphs from every section in the document
for ( Object sectionObj: document.getSections()) {
Section section = (Section)sectionObj;
section.getParagraphs().clear();
}
//Save the result document
document.saveToFile("removeAllParagraphs.docx", FileFormat.Docx_2013);
}
}
Remove a Specific Paragraph in a Word Document in Java
If you find a paragraph that contains duplicate or useless information, Spire.Doc for Java allows you to delete the specified paragraph using Section.getParagraphs().removeAt() method. The following are the detailed steps.
- Create a Document instance.
- Load a Word document using Document.loadFromFile() method.
- Get a specified section of the document using Document.getSections().get() method.
- Remove a specified paragraph in the section using Section.getParagraphs().removeAt() method.
- Save the result document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
public class removeSpecificParagraph {
public static void main(String[] args) {
//Create a Document instance
Document document = new Document();
//Load a sample document from disk
document.loadFromFile("E:\\Files\\test23.docx");
//Get the first section of the document
Section section = document.getSections().get(0);
//Remove the third paragraph in the section
section.getParagraphs().removeAt(2);
//Save the result document
document.saveToFile("removeSpecificParagraph.docx", FileFormat.Docx_2013);
}
}
Remove Blank Paragraphs in a Word Document in Java
When there are many empty paragraphs/lines in a document, it's necessary to remove them to improve readability. The following are the steps to remove all blank paragraphs/lines in a Word document.
- Create a Document instance.
- Load a Word document using Document.loadFromFile() method.
- Traverse through all paragraphs in the document and determine whether the paragraph is a blank paragraph.
- Remove blank paragraphs from the document using Section.getBody().getChildObjects().remove() method.
- Save the result document using Document.saveToFile() method.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
public class removeEmptyLines {
public static void main(String[] args) {
//Create a Document instance
Document document = new Document();
//Load a sample document from disk
document.loadFromFile("E:\\Files\\test230.docx");
//Traverse each paragraph in the Word document
for (Object sectionObj : document.getSections()) {
Section section=(Section)sectionObj;
for (int i = 0; i < section.getBody().getChildObjects().getCount(); i++) {
if ((section.getBody().getChildObjects().get(i).getDocumentObjectType().equals(DocumentObjectType.Paragraph) )) {
String s= ((Paragraph)(section.getBody().getChildObjects().get(i))).getText().trim();
//Determine if the paragraph is a blank paragraph
if (s.isEmpty()) {
//Remove blank paragraphs
section.getBody().getChildObjects().remove(section.getBody().getChildObjects().get(i));
i--;
}
}
}
}
//Save the result document
document.saveToFile("removeEmptyLines.docx", FileFormat.Docx_2013);
}
}
