How can I test if there is a text node following and restrict the test to a certain parent element? By comparing ancestors. In the example I'd like to test if there is text following after the <s/> element up to the enclosing end tag of the <b> element. So, then, this <b> ancestor has to be common between the node you are at, and the nodes being inspected for being non-empty. This test should fire at the first s element because of the following BBB text, but not at the second s element in spite of the following AAA text. The structure below the b element may contain any number of nesting levels and element. Which is why one is dealing with the ancestor. I'd like to include the test in a template which tackles the s element, like <xsl:template match="s[some-test]"> The solution below addresses this, by first filtering following text nodes for having the common ancestor, and then filtering those for being non-white-space-only. It is using XSLT 1.0 ... you don't say which version you are using. Note that on large data sets this may be slow because of the use of the following:: axis. I hope this helps. . . . . . . . . . .
