Empty node strings

[Marius8881]

Hi,
Is it possible to select certain empty node values, "" , and change them to different types, ex, array ? I do not seem to see the option for this., tried it with tagValueProcessor , but it does not see empty "" .

I'm glad you find this repository helpful. I'll try to address your issue ASAP. You can watch the repo for new changes or star it.

@Marius8881 Can you please give some example? I'm working on fxp v4. I can probably consider new requirements in that.

[Marius8881]

 Example:
    <x>0</x>
    <y>44</y>
    <width>2</width>
    <minWidth>1</minWidth>
    <maxWidth>12</maxWidth>
    <height>4</height>
    <minHeight>4</minHeight>
    <maxHeight>48</maxHeight>
    <overlays/>
    <frame>
      <static>true</static>
      <nodePath/>
      <color>transparent</color>
    </frame>
 

<overlays/> is coming as empty, and I can not see the name of the attribute, because of it, even if its set as <overlays> <overlays/> , same for arrays.

[amitguptagwl]

Do you expect overlays = ' ' in case of <overlays> <overlays/> ?

[Marius8881]

Yes, unfortunately we deal with binary data, and need to use xml, and have issues with the types changing, and we needed to change the type value of a node to what we need, that is why is favorable to see them all, even if empty.

Try trimValues: false. But it may add "#text": "\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n", to the output.

closing as no update. reopen it if issue still exists

In my example, I'm parsing this:

<companies>
  <company></company>
</companies>

which parses into this:

companies: {
  company: ''
},

vs.

companies: {
  company: {}
},

Is there an option to control this?

[amitguptagwl]

@fpedroza Currently no. But you can create another issue for a feature request. If there are more users who are looking for the same or similar behavior then we can provide some common solution.

+1 for this issue. I would like to treat an empty tag as a null value, and I cannot process it with the tagValueProcessor because it skips empty nodes.

[dobeerman]

in my case, if specific empty tag exists, I need to replace its value with boolean, but currently, it is impossible due to tagValueProcessor skips empty tags.

[amitguptagwl]

Let's assume 2 situation <a><![CDATA[text]]></a> and <a><tag>text</tag></a>. Should we call tagValueProcessor for <a>?

[amitguptagwl]

I've created a branch "emptyNode_v2" for this change. But not publishing them due to a few pending decisions like when not to call tagValueProcessor.
