Re: to extract the longest string (fwd)

["C.V. Radhakrishnan" <cvr@xxxxxxxxxxxxxxx>]

I tested the following code in SAXON and I could not get the
expected longest string, which is "cxxyycc".

Please check

Thanks


<?xml version="1.0"?>
<table>
<row>
	<col align="l"/>
	<col align="l"/>
	<col align="l"/>
</row>
<row>
	<col align="cxxyy"/>
	<col align="c"/>
	<col align="c"/>
</row>
<row>
	<col align="cxx"/>
	<col align="c"/>
	<col align="c"/>
</row>
<row>
	<col align="cx"/>
	<col align="c"/>
	<col align="c"/>
</row>
