Find and Highlight Text in Specific Paragraphs of Word documents using Java

In the previous article, I showed you how to find all matched text in a Word document and then highlight it with color. This tutorial will demonstrate how to find all matched text in a specific paragraph of a Word document and highlight it.

DEPENDENCY

First of all, you need to get the latest version of Spire.Doc for Java from this link, and then manually add Spire.Doc.jar to your Java program. Or if you use Maven, you can easily import the JAR file by using the following codes in the pom.xml file.

USING THE CODE

The following are detailed steps to find and highlight text in a specific paragraph of a Word document.

l  Initialize a Document object and load a Word sample document.

l  Get a specific section of the document using Document.getSections().get() method.

l  Get a specific paragraph of the section using Section.getParagraphs().get() method.

l  Find matched text in this paragraph using Document.findAllString() method.

l  Get the character format of these text using TextSelection.getAsOneRange().getCharacterFormat() method, and then set the highlight color using CharacterFormat.setHighlightColor() method.

l  Save to another file using Document.saveToFile() method.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TextSelection;

import java.awt.*;

public class FindAllStringsInAParagraph {
    public static void main(String[] args) {
        //Load a Word sample document
        Document doc = new Document("sample.docx");

        //Get first section
        Section section = doc.getSections().get(0);

        //Get second paragraph in this section
        Paragraph para = section.getParagraphs().get(1);

        //Find all "Word" strings in this paragraph
        TextSelection[] textSelections = para.findAllString("Word", false, true);

        //Sets highlight color of all text
        for (TextSelection selection : textSelections)
        {
            selection.getAsOneRange().getCharacterFormat().setHighlightColor(new Color(255, 15, 19));
        }

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