[Revised] Adding IF ELSE into XML code in Extract Structured Data

Help Activities
1

How do I add a conditional statement such as IF ELSE into XML code in Extract Structured Data activity?

I am new to XML so please kindly provide a working XML code solution. Thank you.

[example pseudo code]

<extract>
	<row exact='1'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
	</row>
**IF <column exact='1' name='her' attr='text'> isNullorEmpty THEN**
	<column exact='1' name='him' attr='alt'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
		<webctrl tag='img' idx='1' />
	</column>
**ELSE**	
	<column exact='1' name='her' attr='text'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
	</column>
**END IF**	
</extract>

if attribute of ‘text’ has value null or empty then
…
else
…
end if

[REVISED example pseudo code]

<extract>
	<row exact='1'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
	</row>
**IF <column exact='1' name='her' attr='text'> isNullorEmpty THEN**
	<column exact='1' name='her' attr='alt'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
		<webctrl tag='img' idx='1' />		
	</column>
**ELSE**	
	<column exact='1' name='her' attr='text'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
	</column>
**END IF**	
</extract>

you dont need if-else i think

just put them on top of each other. Data scraping will see which one exists, and will use the one that exists

    <column exact='1' name='her' attr='alt'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
		<webctrl tag='img' idx='1' />		
	</column>	
	<column exact='1' name='her' attr='text'>
		<webctrl tag='div' />
		<webctrl tag='li' idx='1' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='div' idx='3' />
		<webctrl tag='div' idx='1' />
		<webctrl tag='a' idx='1' />
	</column>

Thanks. It seems to work.
But I also get a new empty column named “her1”.

put this in if statement

String.IsNullOrEmpty(String.Join(",", dt.AsEnumerable.Select(function(row) row("her1").ToString).ToList))

this will check if her1 column is empty, if empty then you can delete it

would recommend to scrap the him and her column as two correlated columns and doing the evaluation afterwards on datatable level

7

Yes, that was my original process indeed.

I was wondering if it could be done directly from XML code instead of evaluating the data table afterwards.

8

the available functionality triggered with the XML extract config does not offer an if/else condition functionality so far

9

OK. Thanks for clarifying this issue.
