Searching a pattern in a file.

Shell Programming and Scripting

Hi Guys,

I am writing a shell script to extract only the error message from a log file.

I am having difficulty in searching the highlighted text in the below code.

<runtimeinfo datetime="Sun Apr 04 20:02:52 EDT 2008" docid="" source="RAWDATA" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEValidateException:
com.lxnx.fab.ce.xce.tools.XCEValidateException: validateXML(): Data is not well formed. org.xml.sax.SAXParseException: The element type p must be terminated by the matching end-tag &lt;/p&gt;."/>
</message>

<runtimeinfo datetime="Sun Apr 04 20:03:01 EDT 2008" docid="" source="DOC" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEDocConversionException
: TransformEngine Raw data validation Exception: com.lxnx.fab.ce.xce.tools.XCEValidateException: com.lxnx.fab.ce.xce.tools.XCEValidateException:
::::1:411:410:The content of element type p must match (br|table|a|b|i) ."/>
</message>

  <runtimeinfo datetime="Thu Apr 08 06:08:04 EDT 2008" docid="" source="RAWDATA" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEValidateException: com.lxnx.fab.ce.xce.tools.XCEValidateException: 
::::1:2307:2306:Element type tbody must be declared.
::::1:2595:2594:The content of element type table must match (nl).
::::1:3555:3554:Element type tbody must be declared.
::::1:3843:3842:The content of element type table must match (nl).
::::1:8456:8455:Element type tbody must be declared.
::::1:8744:8743:The content of element type table must match (nl)."/>
</message>

Please suggest some solution.

Thanks in Advance

Is that XML-like message tag suppose to be in one line or it will span over a few lines

If it will span over a few lines, do you also want to display the complete XML-like tag

You need to specific on this

Here's one way to do it with Perl -

$
$
$ cat -n f5
     1  <runtimeinfo datetime="Sun Apr 04 20:02:52 EDT 2008" docid="" source="RAWDATA" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEValidateException:
     2  com.lxnx.fab.ce.xce.tools.XCEValidateException: validateXML(): Data is not well formed. org.xml.sax.SAXParseException: The element type p must be terminated by the matching end-tag &lt;/p&gt;."/>

     5  <runtimeinfo datetime="Sun Apr 04 20:03:01 EDT 2008" docid="" source="DOC" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEDocConversionException
     6  : TransformEngine Raw data validation Exception: com.lxnx.fab.ce.xce.tools.XCEValidateException: com.lxnx.fab.ce.xce.tools.XCEValidateException:
     7  ::::1:411:410:The content of element type p must match (br|table|a|b|i) ."/>
     8  </message>

    10  <runtimeinfo datetime="Thu Apr 08 06:08:04 EDT 2008" docid="" source="RAWDATA" event="ERROR" xceError="com.lxnx.fab.ce.xce.tools.XCEValidateException: com.lxnx.fab.ce.xce.tools.XCEValidateException:
    11  ::::1:2307:2306:Element type tbody must be declared.
    12  ::::1:2595:2594:The content of element type table must match (nl).
    13  ::::1:3555:3554:Element type tbody must be declared.
    14  ::::1:3843:3842:The content of element type table must match (nl).
    15  ::::1:8456:8455:Element type tbody must be declared.
    16  ::::1:8744:8743:The content of element type table must match (nl)."/>
    17  </message>
$
$
$ perl -lne 'BEGIN{$/=""} while(/^<runtimeinfo.*Exception:[ \n:\d]+(.*)."\/>.*$/msg){print "\n==== Exception Message No. ",$i++," ====\n",$1}' f5

==== Exception Message No. 0 ====
The element type p must be terminated by the matching end-tag &lt;/p&gt;

==== Exception Message No. 1 ====
The content of element type p must match (br|table|a|b|i)

==== Exception Message No. 2 ====
Element type tbody must be declared.
::::1:2595:2594:The content of element type table must match (nl).
::::1:3555:3554:Element type tbody must be declared.
