How to replace First Occurance of the Link? [on hold]

I am working with book.xml. I have added lot of Link for page Name with page numbers in Index Part [<secondaryie><link xml:id="ind2" linkend="ind2a">Apricot, Plum, and Raspberry</link>140,141</secondaryie>]. I want to find the page name[Apricot, Plum, and Raspberry] and page number [<author id="page4" />] in file except index tags and find the pageno (<author id="page140" />) and page Name in top of the file and replace the link in the page name[<link xml:id="ind1a" linkend="ind1">Apricot, Plum, and Raspberry</link>].
