Detailed Description

XML Extractor API.

Serializes a text block (paragraphs, spans, font and paragraph attributes) to a self-contained XML representation and applies such XML back to a text block, fitting the new text to the block by shrinking font size and line spacing when required.

Text lives in <tbspan> elements (one per span); all styling is a styles JSON attribute on the

(a para object plus a spans map of attribute->span-indices), so styles reattach by index.

Single text block – a <body> root:

<body xmlns="..." xmlns:xfa="..." xfa:APIVersion="2.7.8021.0">
  <p styles='{"para":{"text-align":"left"},"spans":{"bold":[1],"font-family":{"Helvetica":[[0,2]]}}}'>
    <tbspan>she </tbspan><tbspan>will </tbspan><tbspan>come tomorrow</tbspan>
  </p>
</body>

Whole page – a <page> root with one <block> per text block:

<page xmlns="..." xmlns:xfa="..." xfa:APIVersion="2.7.8021.0">
  <block><p styles='{...}'><tbspan>she will come tomorrow</tbspan></p></block>
  <block><p styles='{...}'><tbspan>second block...</tbspan></p></block>
</page>
