I want to write a script to iterate over each element “NewTempP” with attributes and child element and copy the structure to element “fig” as child element. “NewTempP” and “fig” are siblings.

Xml file:

<sec>
    <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
            <alt-text>Describes a picture</alt-text>
        </NewTempP >
        <p>test</fig>
        <fig> </fig>
    <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
           <alt-text>Describes a picture</alt-text>
    </NewTempP >
    <p>test</fig>
     <fig> </fig>
   ……..
<sec>

What I did:

xmlstarlet ed -L -P -u "//fig[preceding-sibling::*[1][self:: NewTempP/@*]]/inline-graphic" -x "string(../preceding-sibling::NewTempP [1]/@*)" test.xml

It does not work.

The result supposed to look like this:

<sec>
    <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
            <alt-text>Describes a picture</alt-text>
        </NewTempP >
        <p>test</fig>
        <fig>
           <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
              <alt-text>Describes a picture</alt-text>
          </NewTempP >
       </fig>
       <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
           <alt-text>Describes a picture</alt-text>
       </NewTempP >
       <p>test</fig>
       <fig>
         <NewTempP  mimetype="image" mime-subtype="jpeg" xlink:href="image1.jpeg">
              <alt-text>Describes a picture</alt-text>
        </NewTempP >
      </fig>
