Hi David,
Thanks lot for your suggestion.
Actually its for translation of PPTX files. So I have to replace whole
paragraph with its translation.
But paragraph is combination of some <a:r> ie; CTRegularTextRun, and
again <a:r> is parent of <a:t>.
1. I saw XML of each paragraph, but never faced more than one <a:t> in
one <a:r> (CTRegularTextRun), but in code it gives array of T. so
write code in this way.
2. I have to replace whole paragraph content by its translation. Its
not possible to divide translated text as per <a:r> or <a:t>. So I
removed all siblings of <a:r> ie; CTRegularTextRun except 1st one and
I am replacing <a:t> content of 1st CTRegularTextRun of paragraph by
its translation.
3. For blank paragraphs number of ctRegularTextRun is zero I guess. so
while setting its content by
ctRegularTextRun[0].setT("Some Translated Text"); gives
ArrayIndexOutOfBound exception. So I check for length. I
have modified it.
String originalParaText = replaceUnwantedChar(xslfParagraph.getText());
if ( ! originalText.isEmpty()) {
I am doing all operation. So now I don't need to check for length of
CTRegularTextRun[] for that paragraph.
Thanks lot for this suggestion.
4. Now I figured out the difference among
for(int index = 1; index <= ctRegularTextRun.length-1; index++) and
for(int index = ctRegularTextRun.length-1; index > 0 ; index--).
While traversing in forward direction (1st one) it gives
IndexOutOfBoundsException while traversing in backward (2nd one) it
works fine. So I was deleting ctRegularTextRun in backward direction
whereas I was leaving 1st ctRegularTextRun ie; present at 0th index.
but now I can put both.
CTRegularTextRun[] ctRegularTextRun = xslfParagraph.getXmlObject().getRArray();
for(int index = ctRegularTextRun.length-1; index > 0 ; index--){
xslfParagraph.getXmlObject().removeR(index);
}
or
for(int index = 1; index <= ctRegularTextRun.length-1; index++){
xslfParagraph.getXmlObject().removeR(1);
}
Thanks lot for your suggestion.
