  • Hi Saranya,

    Do not enable XMLMapper in pipelineconfig.xml. You need to enable XMLMapper to "Yes" in optionalprocessing.xml file.


    Hope this helps!

  • You can get a more detailed description of the problem by increasing the logging verbosity


    PS>psctrl doctrace on

    PS>psctrl debug on

    Then use doclog to examine the logs. You can get a doclog -a after you have crawled a few problematic URIs. Log location  %FASTSEARCH%\var\log\

    The logs verbosity should be turned off after the investigation or else it starts filling up the disks quickly

  • Hi,

    One of the way to resolve this issue is  remove  this entry <ext name=".xml" mimetype="text/xml" /> from ifilter value in user_converter_rules.xml If possible try to delete it instead of comment it.

    These approach solved my problem.

    Hope it may solve your issue as well.

  • Check this MSDN Article. 

    The item processing pipeline detects the type of content by analyzing the actual data in the retrieved item. If it contains valid XML, it will be treated as XML and converted by using the XML Mapper. Some XML content may not have valid XML declarations and may contain element names that are frequently used in HTML. In such cases, the crawled XML items might be mistaken for HTML items. One solution to this problem is to bypass format detection for crawled items with ".xml" as the file name extension. You can do that by adding the following conversion rule in the configuration file user_converter_rules.xml.

             <ext name=".xml" mimetype="text/xml" />
