If you want to see, what you have already done for a certain project of your repository, SVN offers you the ability to export the log as a XML-File.

svn log -v --xml https://server.org/svn/project

This will show the log directly in your console. If you prefer the output as a file append

> outfile.xml

If you’d like to have a more human readable output, you can use the following xsl, to transform it to a readable html table:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>SVN Log</h2>
<table border="1">
<xsl:for-each select="log/logentry">
<xsl:if test="author='USERNAME'">
<tr>
<td><xsl:value-of select="date"/></td>
<td><xsl:value-of select="author"/></td>
<td><xsl:value-of select="msg"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

Change USERNAME to your svn username and save it to svnstyle.xsl for example.

Now you can use the following command to export and transform the export-xml directly to readable html via:

svn log -v --xml https://server.org/svn/project | xsltproc svnstyle.xsl - > ~/Desktop/svnlog.html

This uses the XSLT-Processor xsltproc, which seams to be preinstalled on a Mac OS X system. But you can replace it with any XSLT-Processor of your choice ;)

The svn command may require username and password – so you may get asked for turing the process.
You can specify a username and password with the parameters –username USERNAME and –password PASSWORD.
But think of the little security issue.
