How to Preserve White Space for OCR
Extensible Markup Language, abbreviated to XML, is a markup language typically used as a set of protocols for encoding local and remote documents into a specific format. Optical Character Recognition (OCR) is a method by which an image-based computer file can be converted into a text-based document, in which all of the text is searchable. You can use the Extensible Stylesheet Language Transformations "XSLT" element "<xsl:preserve-space>" to preserve whitespace, which can be created within an XML file in Notepad.

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="<strip choose element>" />
<xsl:preserve-space elements="<preserve choose element>" />
<xsl:template match="/">
<html>
<body>
<xsl:for-each select="/">
<p>
<xsl:value-of select="value_1" /><br />
<xsl:value-of select="value_2" /><br />
<xsl:value-of select="value_3" /><br />
<xsl:value-of select="value_4" /><br />
</p>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Replace "value_1," "value_2," "value_3" and "value_4" with the specific element values of which you want to preserve and/or strip whitespace. Replace "<strip choose element>" and "<preserve choose element>" with the element values that you specify. This will provide you with the fundamentals on how to preserve white space with OCR XML.
