    ~/drafts/xsl> cat regexp.xsl
    <xsl:transform
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
        version="2.0">

      <xsl:output method="text"/>

      <xsl:template match="/">
        <xsl:apply-templates select="root/test"/>
      </xsl:template>

      <xsl:template match="test">
        <xsl:value-of select="replace(., '\[[^\]]+\]', '')"/>
        <xsl:text>&#10;</xsl:text>
      </xsl:template>

    </xsl:transform>

    ~/drafts/xsl> cat regexp.xml
    <root>
      <test>text [with brackets]</test>
      <test>plain text</test>
      <test>text [with [problematic] brackets]</test>
    </root>

    ~/drafts/xsl> saxon regexp.xml regexp.xsl
    text
    plain text
    text  brackets]

  I'm not sure what you're looking for, but maybe
xsl:analyze-string, xsl:matching-substring and
xsl:non-matching-substring can be of interest.
