I have xml as follows:
<a>
<a>
<d>0</d>
</a>
<a>
<d>99</d>
</a>
</a>
This is my code javascript.
var a = document.getElementsByTagName("a");
var d = a[1].getElementsByTagName("d")[0].firstChild.data;
document.write("d = " + d);
The result is d = 0 but my expected result is d = 99.
Could you help me please?
I want to input only index 1 (a[1]) i do not want to input index 2.
You can use DOMParser function to create a xmlDoc and than read from it required value. The problem was in your element selector.
var text = "<a> <a> <d>0</d></a><a><d>99</d></a></a>"
parser = new DOMParser();
xmlDoc = parser.parseFromString(text,"text/xml");
var dNode = xmlDoc.querySelectorAll('a a:last-child d')[0];
var dNodeValue = dNode.innerHTML;
console.log(dNodeValue);
// 99
So basically you are looking for a[2]:
<a> <-- a[0]
<a> <-- a[1]
<d>0</d>
</a>
<a> <-- a[2]
<d>99</d>
</a>
</a>
Here is the update:
var a = document.getElementsByTagName("a");
var d = a[2].getElementsByTagName("d")[0].firstChild.data;
^---- this is what changed
document.write("d = " + d);
