How to add attribute value to all elements?

[mariod1014]

I have an XML file that requires that the attribute os=" WINDOWS" be included in all elements. Right now some elements include that attribute, but not all. What's the best/easiest way to insert that attribute in all elements where its missing? Thanks for any help.

You could do it easily with XSL:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform">[/URL]
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:if test="not(@os)">
        <xsl:attribute name="os">WINDOWS</xsl:attribute>
      </xsl:if>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

But why are you doing this? Can you not use a namespace?

I'm not a programmer by trade, but a technical writer and I had two weeks to deliver an XML document based on a DTD from the customer. So I only had time to learn XML and have not gotten the time to learn other aspects, as for example, XSL. However, this is all very intriguing and I hope to come to speed on that too. Thanks very much for your help.
