Question

Logging subsystem writes log in xml file.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<log version="1.0">    
<message time="2011-04-11 17:10:10.0020" class="info">
la la la la..
</message>

I assume that writing in login file may crashes. In result xml log file may contain wrong xml data strings

for example

<message ti

Is exist convenient way of clearing xml file from wrong data parts,except of using regexp?

upd:wrong data parts can occur in middle of file not only in the end.

Answer 1

This is a great reason not to use XML as a logging format. Even without crashes, the log is never well-formed XML, since you never close the root tag.

As to how to clean it? Assuming you only get truncated files, read in the file, look for the last "</message>", truncate there, add a "</log>", and try to parse it.
