Re: [xsl] How to produce X when an attribute of an element does not exist or equals Y?

Use this test in your xsl:if:

data-field[(_at_)tag='555'][(_at_)ind1='8' or not(@ind1)]

Hi, I'm new to the listserv and to XSL. Using the XML below and XSLT 1.0, I would like content to appear both when an attribute of an element does not exist and when it equals X. Specifically, I would like the contents of data-field tag 555 to appear if this data-field does not have any "ind1" attribute, or if its ind1 equals 8.

Data fields with indicators versus no indicators in my XML look like this:
<data-field tag="555" ind1="0">
  <subfield code="a">...</subfield>
</data-field>
<data-field tag="555">
  <subfield code="a">...</subfield>
</data-field>

This is the XSLT I have figured out, minus the missing part:
<xsl:if test="data-field[(_at_)tag='555'][(_at_)ind1='8'] | ...or if a data-field with attribute 555 has no attribute ind1">
  <otherfindaid encodinganalog="555">
<xsl:for-each select="data-field[(_at_)tag='555'][(_at_)ind1='8'] | ...or if a data-field with attribute 555 has no attribute ind1">
          <p>
              <xsl:value-of select="."/>
          </p>
      </xsl:for-each>
  </otherfindaid>
</xsl:if>

I would be very grateful for any help. Thank you!
