I am trying to search a string in docx and replace with some other text using java apache poi but it is replacing randomly
getting error as arrayIndexoutofbound Exception in line

it misses some string, it not replaces entire document..please help with sample code
I do something similar in my project at https://github.com/centic9/poi-mail-merge which provides a general mail-merge functionality based on POI. It is using a bit different functionality from XmlBeans which replaces strings in the full XML-content of the document instead of each paragraph separately.
private static void appendBody(CTBody src, String append, boolean first) throws XmlException {
XmlOptions optionsOuter = new XmlOptions();
optionsOuter.setSaveOuter();
String srcString = src.xmlText();
String prefix = srcString.substring(0,srcString.indexOf(">")+1);
final String mainPart;
// exclude template itself in first appending
if(first) {
mainPart = "";
} else {
mainPart = srcString.substring(srcString.indexOf(">")+1,srcString.lastIndexOf("<"));
}
String suffix = srcString.substring( srcString.lastIndexOf("<") );
String addPart = append.substring(append.indexOf(">") + 1, append.lastIndexOf("<"));
CTBody makeBody = CTBody.Factory.parse(prefix+mainPart+addPart+suffix);
src.set(makeBody);
}
}

Let's assume i have a word document, with this body.
Word document before replacing images
private void findImages(XWPFParagraph p) {
for (XWPFRun r : p.getRuns()) {
for (XWPFPicture pic : r.getEmbeddedPictures()) {
XWPFPicture picture = pic;
XWPFPictureData source = picture.getPictureData();
BufferedImage qrCodeImage = printVersionService.generateQRCodeImage("JASAW EMA WWS");
File imageFile = new File("image.jpg");
try {
ImageIO.write(qrCodeImage, "jpg", imageFile);
} catch (IOException e) {
e.printStackTrace();
}
try ( FileInputStream in = new FileInputStream(imageFile);
OutputStream out = source.getPackagePart().getOutputStream();
) {
byte[] buffer = new byte[2048];
int length;
while ((length = in.read(buffer)) > 0) {
out.write(buffer, 0, length);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
}
So this code replaces any image with QR code.
But I have one trouble.
Word Document after replacing
So my question is?
How can I replace only the image i chose or how can i replace inserted figure with text with image generated by my own function?
Detecting the picture and replacing the picture data will be the simplest. In following answer I have shown how to detect and replace pictures by name: Java Apache POI: insert an image "infront the text". If you do not know the name of the embedded picture, a picture also can be detected by alt text. To edit the alt text of a picture, open the context menu by right mouse click on the picture and choose Edit A̲lt Text from that context menu.
In How to read alt text of image in word document apache.poi I have shown already how to read alt text of image.
So code could look like:
import java.io.FileInputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;

This replaces the picture or pictures having alt text "Placeholder QR-Code". All other pictures remain as they are.
Replacing shapes with pictures is very laborious as shapes are stored in alternate content elements (to choice shape and fallback) and so the shape needs to be changed as well as the fallback. If one would let the fallback untouched, then applications which rely on that fallback will further show the old shape. Furthermore detecting shapes by text box content is not really much simpler than detecting pictures by alt text content.
I can replace the text inside the table and footer, but I can't replace the text outside the table. I don't know why.

Want to parse just the first column of the large excel file and store the data into a string by concatenating then using a comma (,) and here I am using Apache POI library and SAX parser to parse the excel file by converting into XML. As the XML file is having two same elements i.e. "Cell" inside the "Row" as the Excel file having two columns in it.
If anyone have an idea then please share.

I have a workbook with two sheets:
Sheet1
Sheet2
And there is a sequence on Sheet2 at the range of A1 to A5:
aa
bb
cc
dd
ee
And in Sheet1, the cell A1 is validated by the sequence in Sheet2.
Excel screenshot
However, sheet.getDataValidations() returns an empty list for this case.
Did I miss something?
public static void main(String[] args) throws Exception {
String filePath = "/Users/fujiexiang/ExcelWorkbook.xlsx";
Workbook workbook = WorkbookFactory.create(new FileInputStream(filePath));
Sheet sheet = workbook.getSheetAt(0);
System.out.println("" + dataValidations + " " + dataValidations.size());
}
"[] 0" was printed out.
Apache POI bases on Office Open XML published for Excel 2007. And Excel 2007 had not supported data validation list constraint coming directly from another worksheet. There had must be created a named range for the data validation list constraint. Now current Excel versions support data validation list constraint coming directly from another worksheet but of course not backwards compatible. That's why apache poi also cannot read those constraints as it only reads CTDataValidations which are from Office Open XML published for Excel 2007.
In the XML the difference looks like so in /xl/worksheets/sheet1.xml:
Excel 2007:
<dataValidation type="list" allowBlank="1" showInputMessage="1" showErrorMessage="1" sqref="A1">
<formula1>Sheet2_A1_A5</formula1>
</dataValidation>
There "Sheet2_A1_A5" is a named range in the workbook that points to Sheet2!A1:A5.
Excel 365:
<x14:dataValidation type="list" allowBlank="1" showInputMessage="1" showErrorMessage="1">
<x14:formula1>
<xm:f>Sheet2!A1:A5</xm:f>
</x14:formula1>
<xm:sqref>A1</xm:sqref>
</x14:dataValidation>
There "Sheet2!A1:A5" is a direct reference to the other worksheet.
As you see, the new x14:dataValidation is in a separate name space. This is not covered by apache poi until now.
What one could do is using low level XML parsing methods to get the new XSSFX14DataValidations additional to the XSSFDataValidations. The following example shows a working draft for how to do this.

Thanks in Advance.......
You can use library like Jsoup
You can get it from here --> Download Jsoup
Here is its API reference --> Jsoup API Reference
Its really very easy to parse HTML content using Jsoup.
Below is a sample code which might be helpful to you..
public class GetPTags {
public static void main(String[] args){
Document doc = Jsoup.parse(readURL("http://www.todaysgoldrate.co.intodays-gold-rate-in-pune/"));
Elements p_tags = doc.select("p");
for(Element p : p_tags)
{
System.out.println("P tag is "+p.text());
}
}
public static String readURL(String url) {
String fileContents = "";
String currentLine = "";
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(new URL(url).openStream()));
fileContents = reader.readLine();
while (currentLine != null) {
currentLine = reader.readLine();
fileContents += "\n" + currentLine;
}
reader.close();
reader = null;
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage(), "Error Message", JOptionPane.OK_OPTION);
e.printStackTrace();
}
return fileContents;
}
}

You can use any of that's apis, but don't parse the HTML with the pure JDK, because it's too painfull.
