Using XSLT, I want to display some examples, however, not show you the original text. My sample file is a real-world example, but the content is a distraction. This simple transformation will convert all of the text nodes (document text) to x’s. During the transformation, the XSLT stylesheet will convert, all the capital, lowercase letters and the numbers to the lower case ‘x’. It will leave the punctuation alone, and the elements’ attributes are left unchanged.
Here is a sample snippet of the input file of S1000D Issue 3, XML:

Here is the transformation stylesheet:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<!– Use indent yes for development, no for production –>
<xsl:output method="xml" indent="yes"/>
<!–
Template match all items, except
SGML Notations and Entities e.g., illustrations.
–>
<xsl:template match="@*|element()|comment()|processing-instruction()" mode="#all">
<xsl:copy>
<xsl:apply-templates select="@*|node()" mode="#current"/>
</xsl:copy>
</xsl:template>
<!– Using the replace function,
context is: string, pattern, replacement string–>
<xsl:template match="text()">
<xsl:value-of select="replace(.,’[a-zA-Z0-9]‘,’x')"/>
</xsl:template>
</xsl:stylesheet>
Here is the result.s tree (a snippet).
