Help! List Or Variable Ignore Empty/missing Elements

[mohsinx1x 0]

Hi Friends,

 

can anyone help me to solved my issue...

 

I'm trying to scrape an element (<span>) which is inside the <DIV>, but since all DIV doesn't have <span> element. my data are getting messed up when im merging with other lists.

 

i guess variables and list ignore missing element values. i tried in scrape attribute, Xpath plugin and Delite CSS. nothing helping me

 

is there anyway to do this.  attaching my sample data..

 

please help!

you have 2 options: compare and verify number of scraped elements in the list and "fix" it if it is no what you expect or scrape element html and parse it and add data one by one to the list

You want to use xpath and specify an offset, since you didn't post code here is a basic example:

set(#html,"<section>
<span class=\"mapMeta\">
<span title=\"3\"/>
<span title=\"4/5\"/>
</span>
</section>

<section>
<span class=\"mapMeta\">
<span title=\"3 star hotel\"/>
</span>
</section>","Global")
set(#example,$plugin function("XpathPlugin.dll", "$Generic Xpath Parser", #html, "//span[@class=\'mapMeta\']/span[2]", "title", ""),"Global")

You need to normalize the data.

If element == nothing:
   put something as a place holder like a 0(zero) or empty

 

this will make your data =

I always plan for the data to not be there and I will show "No data at XYZ".  So when it is there I will grab it and show it.

 

In other words you have to build in Error checks to avoid issues overall.
