Simanchal,

may I ask a couple of stupid questions?

I've removed some dead code & what's left
in the heart of all those nested if's & for's is this:

CTRegularTextRun[] ctRegularTextRun = 
xslfParagraph.getXmlObject().getRArray();

for (int index = ctRegularTextRun.length - 1; index > 0; index--) {
     xslfParagraph.getXmlObject().removeR(index);
}
if (ctRegularTextRun.length > 0) {
     ctRegularTextRun[0].setT("");
}

First you get an Array of all CTRegularTextRuns contained in the XmlObject.
Then you remove them all from the XmlObject.
(they now only exist in the Array you just got)
Finally you set the T Element of (only!) the 1st CTRegularTextRun (if 
present) to "".

Q1) Now I wonder why you need to iterate backwards through the Array?
Q2) Setting the T Element will have no effect (because you have just 
deleted all R's from the XmlObject?!

All the best,
DaveLaw
