includefile procedure

[golmatt]

I must make a procedure in java (preferred, but are accepted others languages, also).

The procedure must process the fields created by user with:

Insert -> Field -> More field.. -> Functions -> Input field ->

Code: Select all

[#includefile "toinclude.odt"]

The process must replace the fields with the contents of the files indicated.

In attachment:
maintemplate.odt (document with fields)
toinclude.odt
toinclude2.odt
result.odf (final result of processing)

Thanks in advance.

Is this a homework project?

I must extends xdocreport reporting functionality

This is a solution

Code: Select all

	        ...
	        com.sun.star.text.XText xText = xTextDocument.getText();
	         
	        com.sun.star.text.XTextFieldsSupplier xTextFieldsSupplier = UnoRuntime.queryInterface(
	        		com.sun.star.text.XTextFieldsSupplier.class, xTextDocument);
	        
	        XEnumerationAccess textFields = xTextFieldsSupplier.getTextFields();
	        
	        XEnumeration enumeration = textFields.createEnumeration();
	         
	        while (enumeration.hasMoreElements()) {
	        	com.sun.star.uno.Any textField = (com.sun.star.uno.Any) enumeration.nextElement();
	        	
	        	com.sun.star.text.XTextField xTextField = (com.sun.star.text.XTextField) 
	        			UnoRuntime.queryInterface(
	        					com.sun.star.text.XTextField.class, textField);

	        	String presentation = xTextField.getPresentation(false);
	        	
	        	if (presentation.startsWith("[#includefile")) {
	        		int start = presentation.indexOf("\"", 0);
	        		int end = presentation.indexOf("\"", start +1);
	        		if (end > start) {
	        			String filenameUrl = presentation.substring(start +1, end);
	        			XTextCursor cursor = xText.createTextCursor();
	        			
	        			cursor.gotoRange(xTextField.getAnchor().getStart(), false);
	        			
	        			xText.removeTextContent(xTextField);

	        			com.sun.star.document.XDocumentInsertable xDocIns = UnoRuntime.queryInterface(
	                    		com.sun.star.document.XDocumentInsertable.class, cursor);
	        			xDocIns.insertDocumentFromURL(filenameUrl, new PropertyValue[0]);
	        		}
	        	}
	        }

How can I optimize the code by testing if the xTextField is an Input Field before getPresentation call?

Every textfield type needs to support characteristic services.

Code: Select all

REM Basic:
...
textFields = ThisComponent.TextFields
For Each textField In textFields
    If textField.supportsService("com.sun.star.text.TextField.Input") Then
        REM Whatever you want to do
    End If
Next textField
...

I didn't find the corrispondent "textField.supportsService("com.sun.star.text.TextField.Input")" in java.

I'm not a user of java, but...

supportsSevice() doesn't need a specific implementation for java, but is a method of the uno object which must work as excpected as soon as the object is accessible at all the uno way. If not, the bridge is broken.

Did you correctly instantiate the ServiceManager for uno in your java code?
Does anything using uno services work as expected in your program?
How did you get access (open/create) to the document?
What do you get with aVariable = myTextField.getSupportedServiceNames()?
Did you regard that the service names are compared for identity (case sensitive)?

There are not these methods:

Code: Select all

textField.getSupportedServiceNames()
xTextField.getSupportedServiceNames()
textField.supportsService(...)
xTextField.supportsService(...)

As I already told, I am not a user (nor a friend) of Java. My only glances on the Language/System were about 20 years ago and didn't convince me of needing to study it to more detail. The code you posted didn't change my mind, in specific not concerning the usage controlling LibreOffice/AOO. (I'm not sure whether or not the bloated C-like appearance is unavoidable.)
Anyway: The interface XServiceInfo (https://api.libreoffice.org/docs/idl/re ... 18f9881e74) is an indispensable means using the uno API. If the bridge from your Java to the API cannot be configured to support it, it isn't suitable for the purpose.
You surely studied https://wiki.openoffice.org/wiki/Docume ... _Implement or similar info.
