Using of Dart XML in Flutter

[Sandi Kastelic]

Dear sir,

Please, I hope someone can help me with usage of Dart XML in Flutter.  I would like to use it for reading an xml file as it is bellow. So far, I can open file, get it into a string and do this in code:

 

    if (masterFile.length > 0) {

      var skus = xml.parse(masterFile);

      print(skus.toString());

      skus.findAllElements("Item");

      var reader =

          xml.XmlReader(onStartElement: (name, attributes) => print(name));

      reader.parse(masterFile);

    }

 

 

With this, I get all names for all items. But, how can I get each item one by one, together with field values, so I can write records into database one by one? Maybe you can point me to some sample?

 

Regards,

Sandi

XML sample:

 

<?xml version="1.0" standalone="yes"?>

<Items>

  <Item>

    <BAR>0000000000005       </BAR>

    <BAR_DESC>BELGIOIOSO SNKNG                                                                                    </BAR_DESC>

    <QTY>0.000</QTY>

    <PRICE>0.0000</PRICE>

  </Item>

  <Item>

    <BAR>0000000000001       </BAR>

    <BAR_DESC>MISS C WATER                                                                                        </BAR_DESC>

    <QTY>0.000</QTY>

    <PRICE>0.0000</PRICE>

  </Item>

  <Item>

    <BAR>0000000000002       </BAR>

    <BAR_DESC>MISS C TOTE BAG                                                                                     </BAR_DESC>

    <QTY>0.000</QTY>

    <PRICE>0.0000</PRICE>

  </Item>

</Items>

Try reading this:

https://pub.dartlang.org/packages/xml

Or as they used to say: RTFM!

getValue(Iterable<xml.XmlElement>  items) {
  var textValue;
  items.map((xml.XmlElement node) {
    textValue = node.text;
  }).toList();
  return textValue;
}
