How to use Java to replace text and pictures in Word

Preface

In Word, you can find and replace specified text through the replace function, either individually or in full. In addition to common text replacement methods, we will also introduce methods of using various objects for replacement, such as:

1. Specify the string content to replace the text (via the method replce(matchString, newValue, caseSensitive, wholeWord); Directly specify the new string content to be replaced)

2. Get the document content replacement text (replace the specified text through the method replace(String matchString, TextSelection textSelection, boolean caseSensitive, boolean wholeWord);)

3. Image replacement text

4. Image replacement image

Use tools and jar import:

Need to use Free Spire.Doc for Java 's jar package can be manually downloaded and decompressed to import the Spire.Doc.jar file into the Java program, or it can be downloaded and imported through the maven repository.

1. Specify the string content replacement text

import com.spire.doc.*;

public class ReplaceTextWithText {
    public static void main(String[] args) {
        //加载文档
        Document doc = new Document();
        doc.loadFromFile("test.docx");

        //要替换第一个出现的指定文本，只需在替换前调用setReplaceFirst方法来指定只替换第一个出现的指定文本
        //doc.setReplaceFirst(true);

        //调用方法用新文本替换原文本内容
        doc.replace("系统测试", "System Testing", false, true);

        //保存文档
        doc.saveToFile("ReplaceAllText.docx",FileFormat.Docx_2013);
        doc.dispose();
    }
}

2. Get the document content replacement text

import  com.spire.doc.*;
import com.spire.doc.documents.TextSelection;

public class ReplaceTextWithDocument {
    public static void main(String[] args) {
        //加载文档1
        Document doc1 = new Document();
        doc1.loadFromFile("test.docx");

        //加载文档2
        Document doc2 = new Document();
        doc2.loadFromFile("TargetFile.docx");
        //查找文档2中的指定内容
        TextSelection textSelection = doc2.findString("Falling under the scope of black box testing, " +
                "system testing is a phase in the software " +
                "testing cycle where a total and integrated" +
                " application /system is tested.",false,false);

        //用文档2中查找到的内容替换文档1中的指定字符串
        doc1.replace("System Test, ST",textSelection,false,true);

        //保存文档1
        doc1.saveToFile("ReplaceTextWithDocument.docx",FileFormat.Docx_2013);
        doc1.dispose();
    }
}

Two for testing The document is as follows. Replace the text content in document 2 with the specified text content in document 1:

Replacement result:

3. Image replacement text

import com.spire.doc.*;
import com.spire.doc.documents.TextSelection;
import com.spire.doc.fields.DocPicture;
import com.spire.doc.fields.TextRange;

public class ReplaceTextWithImg {
    public static void main(String[] args) {
        //加载文档
        Document doc = new Document("test.docx");
        //查找需要替换的字符串
        TextSelection[] textSelection = doc.findAllString("系统测试",true,false);
        int index ;

        //加载图片替换文本字符串
        for (Object obj : textSelection) {
            TextSelection Selection = (TextSelection)obj;
            DocPicture pic = new DocPicture(doc);
            pic.loadImage("tp.png");
            TextRange range = Selection.getAsOneRange();
            index = range.getOwnerParagraph().getChildObjects().indexOf(range);
            range.getOwnerParagraph().getChildObjects().insert(index,pic);
            range.getOwnerParagraph().getChildObjects().remove(range);
        }
        //保存文档
        doc.saveToFile("ReplaceTextWithImage.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}

4. Image replacement image

import com.spire.doc.*;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.DocPicture;

public class ReplacePictureWithPicture {
    public static void main(String[] args) {
        //加载Word文档
        Document doc = new Document();
        doc.loadFromFile("sample.docx");

        //获取文档中的指定段落
        Section section = doc.getSections().get(0);
        Paragraph para = section.getParagraphs().get(0);
        //替换段落中的第一张图片
        Object obj = para.getChildObjects().get(0);
        if(obj instanceof DocPicture){
            DocPicture pic = (DocPicture)obj;
            pic.loadImage("tp.png");
        }

        /*//批量替换图片
        for(int i =0;i < section.getParagraphs().getCount();i++){
            Object obj = section.getParagraphs().get(i).getChildObjects();
            if(obj instanceof DocPicture){
                DocPicture pic = (DocPicture)obj;
                pic.loadImage("tp.png");
            }
        }*/

        //保存结果文档
        doc.saveToFile("ReplaceWithImage.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}
