[oXygen-user] Find and replace with lowercase

[Oxygen XML Editor Support]

Hello,

Unfortunately that's not possible with the Find/Replace tool from 
Oxygen. It only supports Java regular expressions which do not have the 
ability to lowercase/uppercase (as  opposed to Perl 5 regular expressions).

Alternative solutions:
1. (for less then a hundred matches) Use "Find All" to obtain a list 
with all matches and then manually navigate them (Ctrl+Shift+] / 
Ctrl+Shift+[) and for each match use the Document > Source > To Lower 
Case action. You can assign a shortcut to this action in Options > Menu 
Shortcut Keys (search in the filter for 'to lower').

2. (for a hundred or more) Use an XSLT stylesheet that processes the XML 
and lowercases the values of those attributes @fileref).
e.g.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output method="xml"/>
     <!-- Match document -->
     <xsl:template match="/">
         <xsl:apply-templates mode="copy" select="."/>
     </xsl:template>

     <xsl:template 
match="@fileref[parent::*:imagedata/parent::*:imageobject/parent::*:mediaobject]" 
mode="copy">
         <xsl:attribute name="fileref" select="lower-case(.)"/>
     </xsl:template>
     <!-- Deep copy template -->
     <xsl:template match="node()|text()|@*" mode="copy">
         <xsl:copy>
             <xsl:apply-templates mode="copy" select="@*"/>
             <xsl:apply-templates mode="copy"/>
         </xsl:copy>
     </xsl:template>
     <!-- Handle default matching -->
     <xsl:template match="*"/>
</xsl:stylesheet>
This will remove the DOCTYPE if any, so you'll have to manually put it back.
Also note that by default a transformation expands the attribute 
defaults (from the DTD/schema). You can disable that in the 'Advanced 
options' (cogwheel button) of the Saxon 9 transformer when configuring 
the transformation scenario.
