Subject Regex Transformer Error
Date Wed, 05 Nov 2008 18:18:33 GMT
Hi,

I am using Solr 1.3 data import handler. One of my table fields has html
tags, I want to strip it of the field text. So obviously I need the Regex
Transformer.

I added transformer="RegexTransformer" attribute to my entity and a new
field with:

<field sourceColName="content" column="content" regex="English"
replaceWith="XXXXX"/>

Every thing works fine. The text is replace without any problem. The provlem
happend with my regular experession to strip html tags. So I use
regex="<(.|\n)*?>". Of course the charecters '<' and '>' are not allowed in
XML. I tried the following
regex="&lt;(.|\n)*?&gt;" and regex="&#3C;(.|\n)*?&#3E;" but I get the
following error:

The value of attribute "regex" associated with an element type "field" must
not contain the '<' character. at
com.sun.org.apache.xerces.internal.parsers.DOMParser.parse(Unknown Source)
...

The full stack trace is following:
