I am using Apache POI to generate docx files from a template. There doesn't seem to be an obvious way to replace all text in a paragraph and the documentation is pretty scarce. Right now I am able to read a document by looping through its paragraphs, then looping through each paragraph's runs, then looping through each run's text... This works pretty well and I can replace the contents of a text in a run, but my template placeholders (example: <>) may be split into several runs, which makes it really complicated to match and replace. Is there a way to set the contents of a XWPFParagraph? Or at least a way to zap all runs in a paragraph and create my own runs?
Here is what I have so far:
public static void main(String[] args) {
InputStream fs = null;
try {
fs = new FileInputStream("C:\\sample1.docx");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
XWPFDocument doc = null;
try {
doc = new XWPFDocument(fs);
} catch (IOException e) {
e.printStackTrace();
}
for (int i = 0; i < doc.getParagraphs().length; i++) {
XWPFParagraph paragraph = doc.getParagraphs()[i];
paragraph.getCTP().getRArray().
// This will output the paragraph's contents.
System.out.println(paragraph.getParagraphText());
for (int j = 0; j < paragraph.getCTP().getRArray().length; j++) {
CTR run = paragraph.getCTP().getRArray()[j];
for (int k = 0; k < run.getTArray().length; k++) {
CTText text = run.getTArray()[k];
// This will output the text contents
System.out.println(text.getStringValue());
// And this will set its contents
text.setStringValue("Success!");
}
}
}
try {
doc.write(new FileOutputStream("C:\\output.docx"));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
