Master slide content is not replaced on update (Java)

We are already getting Latest version aspose library (19.12).
When I try to replace a text “Test” to “Tested” in pptx file,
After replacement I am getting same text is available in a master slides.

Implemented code:

// Initialize License Instance
com.aspose.slides.License license = new com.aspose.slides.License();
// Call setLicense method to set license
license.setLicense(TextReplacer.class.getResourceAsStream("/Aspose.Total.Java.lic"));

//Instantiate the presentation
final FileInputStream fis = new FileInputStream(filePath);
Presentation pptPresentation = new Presentation(fis);
//Get all text boxes in the presentation
ITextFrame[] tb = SlideUtil.getAllTextFrames(pptPresentation, true);
for (int i = 0; i < tb.length; i++)
for (IParagraph para : tb[i].getParagraphs())
for (IPortion port : para.getPortions()) {
String currentSearchString = “Test”
//Find text to be replaced
if (port.getText().contains(currentSearchString)) {
String str = port.getText()
String regex = getEscapeString(currentSearchString);
Pattern pattern = Pattern.compile(regex);
// Step 2: Allocate a Matcher object from the Pattern, and provide the input
Matcher matcher = pattern.matcher(str);
// Step 3: Perform the matching and process the matching result
String outputStr = matcher.replaceAll(toReplace);
port.setText(“Tested”);
}
}
}

/**

  • get escape search string
  • @param searchString
  • @return special character escape searchString
    */
    public static String getEscapeString(String searchString) {
    String search_str_esc = escapeRE(searchString);
    String[] split = search_str_esc.split("\ “);
    String search_pattern = “[\n\r\s\t]+”.join(” ",split);
    String pattern = “(?<![\/])” + search_pattern + “(?!\b.(com|co)\b)”;
    return pattern;
    }

@Amaran,

I have observed the issue shared and request you to please try using latest Aspose.Slide for .NET 20.2 on your end. In case the issue is still prevailing then please share the source presentation and output presentation with us for further investigation.
