我是Apache POI的新手,我在更换文本方面遇到了麻烦。
我在这里复制了我的代码Replacing a text in Apache POI XWPF not working
它有效,但它不会取代文本而是连接它。 因此,如果我有“快速棕色狐狸跳过”并用“下”替换“结束”。我得到“快速的棕色狐狸跳过快速的棕色狐狸跳跃”。
有什么问题?
所以这是代码:
public class testPOI {
public static void main(String[] args) throws Exception{
String filepath = "F:\\MASTER_DOC.docx";
String outpath = "F:\\Test.docx";
XWPFDocument doc = new XWPFDocument(new FileInputStream(filepath));
for (XWPFParagraph p : doc.getParagraphs()){
int numberOfRuns = p.getRuns().size();
// Collate text of all runs
StringBuilder sb = new StringBuilder();
for (XWPFRun r : p.getRuns()){
int pos = r.getTextPosition();
if(r.getText(pos) != null) {
sb.append(r.getText(pos));
}
}
// Continue if there is text and contains "test"
if(sb.length() > 0 && sb.toString().contains("test")) {
// Remove all existing runs
for(int i = 0; i < numberOfRuns; i++) {
p.removeRun(i);
}
String text = sb.toString().replace("test", "DOG");
// Add new run with updated text
XWPFRun run = p.createRun();
run.setText(text);
p.addRun(run);
}
}
doc.write(new FileOutputStream(outpath));
}
}
编辑1:这是真的!我尝试更换第二轮工作正常。第一轮运行有问题。有人能指出来吗?
答案 0 :(得分:0)
我试过这个。它有效。
public class testPOI {
public static void main(String[] args) throws Exception{
String filepath = "F:\\MASTER_DOC.docx";
String outpath = "F:\\Test.docx";
XWPFDocument doc = new XWPFDocument(new FileInputStream(filepath));
for (XWPFParagraph p : doc.getParagraphs()){
int numberOfRuns = p.getRuns().size();
// Collate text of all runs
StringBuilder sb = new StringBuilder();
for (XWPFRun r : p.getRuns()){
int pos = r.getTextPosition();
if(r.getText(pos) != null) {
sb.append(r.getText(pos));
}
}
// Continue if there is text and contains "test"
if(sb.length() > 0 && sb.toString().contains("test")) {
// Remove all existing runs
for(int i = numberOfRuns; i >=0 ; i--) {
p.removeRun(i);
}
String text = sb.toString().replace("test", "DOG");
// Add new run with updated text
XWPFRun run = p.createRun();
run.setText(text);
p.addRun(run);
}
}
doc.write(new FileOutputStream(outpath));
}
}
