    copied!<p>Below is the XML structure. Its a specimen of my original structure, not the exact.</p> <pre><code>&lt;Docs&gt; &lt;Doc&gt; &lt;Para&gt; &lt;P n="1"&gt;&lt;B&gt;Constants : T&lt;/B&gt;he value of pi is 3.14&lt;/P&gt; &lt;P n="2"&gt;pi is a geometric term.&lt;/P&gt; &lt;/Para&gt; &lt;/Doc&gt; &lt;Doc&gt; &lt;Para&gt; &lt;P n="1"&gt;&lt;B&gt;Constants : T&lt;/B&gt;he value of g is 9.81 m/sqr of sec&lt;/P&gt; &lt;P n="2"&gt;g is a acceleration due to gravity.&lt;/P&gt; &lt;/Para&gt; &lt;/Doc&gt; &lt;Doc&gt; &lt;Para&gt; &lt;P n="1"&gt;&lt;B&gt;Constants : T&lt;/B&gt;he value of c is 3.00 x 10 power 8 m/sec&lt;/P&gt; &lt;P n="2"&gt;c is a speed of light in vacuum.&lt;/P&gt; &lt;/Para&gt; &lt;/Doc&gt; &lt;/Docs&gt; </code></pre> <p>I have generated XML files programmatically. The <code>B</code> node has data <code>Constant : T</code>, where as it should be only <code>Constants :</code>. I have written an XQuery to do the necessary changes, but its not working as expected.</p> <p>below is the XQuery - Version 1</p> <pre><code>for $x in doc('doc1')//Doc where $x/Para/P[@n="1"]/B/text()="Constants : T" return let $p := $x/Para/P[@n="1"] let $pText := concat("T", $p/text()) let $tag := &lt;P n="1"&gt;{$pText}&lt;/P&gt; return ( delete node $p, insert node $tag as first into $x/Para, insert node &lt;B&gt;Constants :&lt;/B&gt; as first into $x/Para/P[@n="1"] ) </code></pre> <p>Version - 2 (Smaller, sweeter but not working !!!)</p> <pre><code>let $b := &lt;B&gt; Constants :&lt;/B&gt; for $x in doc('doc1')//Doc/Para[P[@n="1"]/B/text()="Constants : T"]/P[@n="1"] return ( replace value of node $x with concat("T", $x/text()), insert node $b/node() as first into $x ) </code></pre> <p>Neither query is inserting <code>&lt;B&gt;Constants : &lt;/B&gt;</code>. Can anybody help me on this?</p>
