Below I mentioned the Code. I need how to replace it using id numbers

Need to replace <xref ref-type="bibr" rid="b0001">Ewald <italic>et al.</italic>, 1993</xref> as <xref ref-type="bibr" rid="Ewald1">Ewald <italic>et al.</italic>, 1993</xref>

To Take the text from the ref-list id and replace in call outs

Example:

<xref ref-type="bibr" rid="b0001">Ewald <italic>et al.</italic>, 1993</xref>

<bib id="CIT-Ewald-b0001"> take the text found in id inbetween the text CIT- and -b0001 i.e. "Ewald" and find the id found in body text i.e. rid="b0001" and replace as rid="Ewald1"

<bib id="CIT-Kasten-b0002"> take the text found in id inbetween the text CIT- and -b0002 i.e. "Kasten" and find the id found in body text i.e. rid="b0002" and replace as rid="Kasten2"

Now u onderstand what I am asking

<body><p>Approximately 125&#x2009;231 joint replacements and 442 total
+ elbow replacements were performed in England and Wales in 2013 accor
+ding to data collected by the <xref ref-type="bibr" rid="b0004">Natio
+nal Joint Registry (2014)</xref>. Elbow replacements have a deep infe
+ction rate ranging from 1 to 12&#x2009;% (<xref ref-type="bibr" rid="
+b0001">Ewald <italic>et al.</italic>, 1993</xref>; <xref ref-type="bi
+br" rid="b0002">Kasten &#x0026; Skinner, 1993</xref>), with an estima
+ted mean of 5&#x2009;% (<xref ref-type="bibr" rid="b0003">Little <ita
+lic>et al.</italic>, 2005</xref>).</p><p><italic>Staphylococcus aureu
+s</italic> and <italic>Staphylococcus epidermidis</italic> together a
+ccount for approximately 50&#x2009;% of the agents isolated from infe
+cted joint prostheses, making them the most common causative bacteria
+ (<xref ref-type="bibr" rid="b0005">Tattevin <italic>et al.</italic>,
+ 1999</xref>). Bacteria responsible for elbow prostheses infections i
+nclude <italic>Staphylococcus aureus</italic>, <italic>Staphylococcus
