Variables in the header and footer are not replaced with the values

[ssriharan]

There are cases where the variable is in the multiple runs, values are not substituted, this is mostly happening with the variables added in header and footer.

#{testVariable} is recognized as #, {testVariable and } runs, so it's not properly replaced with the value.

I believe this has to be fixed in the InsertStrategy implementation, something like below;

` public void insert(Insert insert, Variable variable) {
if (!(insert instanceof TextInsert)) {
return;
}
if (!(variable instanceof TextVariable)) {
return;
}

	TextInsert textInsert = (TextInsert) insert;
	TextVariable textVariable = (TextVariable) variable;

	XWPFParagraph paragraph = textInsert.getParagraph();
	TextSegement found = paragraph.searchText(textInsert.getKey().getKey(), new PositionInParagraph());

	if (found != null) {
		if (found.getBeginRun() == found.getEndRun()) {

			for (XWPFRun run : paragraph.getRuns()) {
				String runText = run.getText(0);
				if (StringUtils.contains(runText, textInsert.getKey().getKey())) {
					runText = StringUtils.replace(runText, textVariable.getKey(), textVariable.getValue());
					run.setText(runText, 0);
				}
			}
		} else {
			StringBuilder b = new StringBuilder();
			for (int runPos = found.getBeginRun(); runPos <= found.getEndRun(); runPos++) {
				XWPFRun run = paragraph.getRuns().get(runPos);
				b.append(run.getText(run.getTextPosition()));
			}
			String connectedRuns = b.toString();

			if (StringUtils.contains(connectedRuns, textInsert.getKey().getKey())) {
				connectedRuns = StringUtils.replace(connectedRuns, textVariable.getKey(), textVariable.getValue());
				XWPFRun partOne = paragraph.getRuns().get(found.getBeginRun());
				partOne.setText(connectedRuns, 0);
			}

			for (int runPos = found.getBeginRun() + 1; runPos <= found.getEndRun(); runPos++) {
				XWPFRun partNext = paragraph.getRuns().get(runPos);
				partNext.setText("", 0);
			}
		}
	}
