Read attributes from XML

[Cif1983]

Hi, I need to read data from an XML file, but since I'm fairly new to Labview and XML, I could really use some help.

Below is the content of the XML (part of it)

I need to read the serial number and weight from resource "ID1" and "ID8".

<resource name="printer">

<resource name="ID1">

- <counters>

  <counter description="product number" name="48030" type="lifetime" value="11081034" />

  <counter description="Weight [g]" name="48031" type="lifetime" value="692" />

  <counter description="Warm hours [h]" name="48032" type="lifetime" value="1454" />

  </counters>

<resource name="ID8">

- <counters>

  <counter description="product number" name="48030" type="lifetime" value="11081042" />

  <counter description="Weight [g]" name="48031" type="lifetime" value="692" />

  <counter description="Warm hours [h]" name="48032" type="lifetime" value="1454" />

  </counters>

</resource>

Why don't you try using Easy XML toolkit.

Its Demo version is free. 🙂

Here's a way to do it using the LabVIEW XML Parser functions.

Hi, thanks for the replies.

I started out with putting all data in an array, but it is simply to complex.

I had a look at EasyXML and it looks very promessing, but I can someone please help me with creating a cluster for the above mentioned XML?

Thanks,

Here is how to use the JKI Easy XML functions to convert between clusters and XML strings.

Thank you Ben, it was very helpful.

How'd you use the Easy XML to convert from XML to cluster or array of clusters for the same example?

[MangeshD]

Hi,

 Refer to example:

"<LabVIEW>\examples\JKI\EasyXML" .

Also you can get complete documetation for the same here

if you need to create parse data from XML you'll need to create the custer control (or constant as i do in the example in link given below) then parse the data from the XML to the output cluster.

I have created the code for your XML data here in dropbox (unable to attach VI on this forum due to error)

[winterishere8]

When you paste the XML code it into the string control, the resulting cluster is not populated correctly.

Also, would the behavior be the same if I create an array of clusters for counter?

It helped a lot, getting all the attributes from a file

Thanks

Could you please explain why you gave //*@ as the string constant to get all matched nodes

thanks in advance
