Get_DCR problem

I have a dcr having a Visual Format Data node. I am using inner_xml function on another node of the same XML and retreiving the modified XML by get_dcr function before writing out the final dcr. However, get_dcr function usage produces unwanted results for the Visual Format data e.g.

Data before calling get_dcr result:
& lt;b & gt;This & lt;b/& gt; is a test & lt;a href="test" /& gt;

Data after calling get_dcr result:
& lt;b>This & lt;b/> is a test & lt;a href="test" />

The above example shows that the ">" is transformed as ">" for some reason in the resultant XML although the < remains unchanged. Is there a way to fix that? If not, does anyone know an efficient regex to fix that in the given node?

First - are you sure this is causing a problem? Despite how it looks, it is possible that XML parsers will accept spurious '>'s whereas they will not accept spurious '<'s

If it is causing a problem - you will have to get the contents of the VFE node separately so that you can encode it before putting it back into the structure - I believe HTML::Entities - encode_entities() will do what you want (read the perldoc for more information).

The dcr seems to break due to those unwanted ">". I am calling the get_dcr method after making the changes by calling the inner_xml. I can suppress the ">" with the following:

encode_entities($input, '>')

but the issue would be how to get to that node and make change without calling get_dcr or similar method. If I do the regex substitution in the resultant xml, it can possibly change a whole lot more while the encode_entities has to have the correct string passed to it which means that I have to access th VF node, change it and put it back in the xml without calling any method that may change it back.

As I said - you'll have to get that node separately so you can encode it and stick it back into your desired result structure to put it all back in the DCR - but this begs the question - what are you actually trying to accomplish?
