Sample Code

The detailed steps and complete sample code are as follows.

  • Create a Document instance.
  • Load a sample Word document using Document.loadFromFile() method.
  • Get a specific section of the Word document using Document.getSections().get() method.
  • Get a specific paragraph of the section using Section.getParagraphs().get() method.
  • Loop through the child objects of the paragraph, and convert each child object as a text range if it is plain text. Then hide the text range using TextRange.getCharacterFormat().setHidden(boolean value) method.
  • Save the document to another file using Document.saveToFile() method.
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;

public class HideParagraph {
public static void main(String[] args) {
//Create a Document instance
Document document = new Document();

//Load a sample Word document
document.loadFromFile("Film.docx");

//Get a specific section of Word
Section sec = document.getSections().get(0);

//Get a specific paragraph of the section
Paragraph para = sec.getParagraphs().get(3);

//Loop through the child objects
for (Object docObj : para.getChildObjects()) {
DocumentObject obj = (DocumentObject)docObj;

//Determine if a child object is an instance of TextRange
if ((obj instanceof TextRange)) {
TextRange range = ((TextRange)(obj));

//Hide the text range
range.getCharacterFormat().setHidden(true);
}
}

//Save the document to another file
document.saveToFile("hideParagraph.docx", FileFormat.Docx_2013);
}
}
