[oXygen-user] Find and replace with lowercase

[Yudong Chen]

Hello, everyone,

I was trying to find and change some attribute values to lowercase in hundreds of xml files, using the Find and Replace feature of Oxygen, but without success.

For example, there are many values reading like this (just example):

<mediaobject>
<imageobject>
<imagedata fileref="../images/AbcdEfg.png" width=".81cm"/>
</imageobject>
</mediaobject>

I succeeded in finding all of those values using regular expression but I don't know how to replace them with their lowercase versions.

Have you ever succeeded in doing the same thing? Would you please share the way you did it? Or it is just impossible with Oxygen?

Thanks,

Yudong

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.

If you're processing a doc with a DOCTYPE, the following thread includes
a python script that cloaks entities and restores the DOCTYPE:

In this case, however, it might just be easier to use sed on the xml
file to lowercase the file names to begin with.
