#2 Reading Arguments from XML

[Anonymous]

Hi,

I am evaluating the JOX software that is very easy to
convert Java Beans object to XML and back. It is truly
amazing. I am actually stuck in one important scenario:

My XML file looks like:
<item-list>
<stock_info name="YYY">SYM</stock_info>
</item-list>

I want to write an particular java bean code to get
access to symbol SYM.
can you please tell me how to do it?

thanks. I appreciate your help.

Hi all,
I have a created a patch for this. You only have to modify
the JOXSAXBeanInput class. The patch is:
/home/alva/src/Jox-1.17b3/com/wutka/jox >diff -bw
JOXSAXBeanInput.java Orig_JOXSAXBeanInput.java

< else if(stackOb instanceof ObjectInfo)
< {
< if (null != valueStr)
< {
< Attributes myAtts;
< myAtts = new AttributesImpl();
<
< ((AttributesImpl)myAtts).addAttribute

<
< processAttributes((ObjectInfo) stackOb,
myAtts);
< }
< }

1128,1139d1094
<
< // Begin Change --- Alva Powell 7/28/04
< public void setValueLoaded(boolean flag)
< {
< valueLoaded = flag;
< }
<
< public boolean getValueLoaded()
< {
< return valueLoaded;
< }
< // End Change --- Alva Powell 7/28/04

You will have to add a method public void setVal(String
value) to your class in order for this patch to work. Sorry I
know it is a little UGLY... Just didn't have time to come up
with a better solution.

One more follow up on this. After a nights sleep I realized I
could make a slight mod and this would actually work much
better.

Change the following line (which is new line 671)
((AttributesImpl)myAtts).addAttribute
("","Val","Val","CDATA",valueStr);

to:

((AttributesImpl)myAtts).addAttribute
("",unqualifiedName,unqualifiedName,"CDATA",valueStr);

This will cause JOX to use setStock_info in the above
example. Also the parameter type in the setStock_info(String
value) can be any simple type. I am not sure if you can get
away with a complex (object) here. I don't think so, but I
don't need to in my application so I am NOT going to play
with it to try and figure it out.
