[Expat-discuss] numeric entities

[Lee Brown]

Okay, I used xmlwf from 1.95.8 this way:

xmlwf -c -m -d tmp < test.xsl

test.xsl looks like this:

<?xml version="1.0"?>
<outer>
<text>BEFORE&#64;&amp;AFTER</text>
</outer>

The output file looks like this:

<document>
<starttag name="outer" byte="22" nbytes="7" line="2" col="0"/>
<chars str="&#10;" byte="29" nbytes="1" line="2" col="7"/>
<starttag name="text" byte="30" nbytes="6" line="3" col="0"/>
<chars str="BEFORE" byte="36" nbytes="6" line="3" col="6"/>
<chars str="" byte="42" nbytes="5" line="3" col="12"/>
<chars str="&amp;" byte="47" nbytes="5" line="3" col="17"/>
<chars str="AFTER" byte="52" nbytes="5" line="3" col="22"/>
<endtag name="text" byte="57" nbytes="7" line="3" col="27"/>
<chars str="&#10;" byte="64" nbytes="1" line="3" col="34"/>
<endtag name="outer" byte="65" nbytes="8" line="4" col="0"/>
</document>

Notice the strings "BEFORE" and "AFTER" in the input file, which are
separated by a numeric entity (the value of the at-sign) and a standard
entity.  The standard entity is repeated as a character value in the xmlwf
output, but the numeric entity is discarded.

But, if I do not use the -m option, I do see an exact copy of my input file.

This is the behavior I might expect for external entities, but it is my
understanding that numeric entities should work like the "standard"
pre-defined entities.

It is important to repeat that this appears to be a change in the behavior
from an earlier release.  Is this a bug that everyone sees, or is it a bug
in my port (in which case are there any suggestions about where to look), or
is my XML file incorrect (in which case, what would be correct)?

P.S., the xmlwf man page asks why anyone would want to use the -c, -m,
and -d options.  I found them quite useful to see if expat would indeed make
an exact copy of the input.

Thanks,
Lee
