xmldom getting elements by id 1

[stinkybee]

I need to get the contents of several nodes based on their parent nodes id attribute.

XML looks like this

<?xml version='1.0' ?>
<data>
<page id="1">
....other elements
</page>
<page id="2">
....other elements
</page>
</data>

I need to use asp to get all values within elements that have a parent node with a specific id. For, example, getting all of the elements within the "page" node that has an id of 1

I did find an xmldom resource which listed things like "nodeByID" but I couldn't get that to work.

Thanks in advance for any help on this

Thanks for that but my eyes are bleeding from looking through such resources for the last 8 hours. If anyone could provide an actual working example that would be great.

 

[DotNetGnat]

did you try this simple example from

http://www.w3schools.com

<script type="text/vbscript">

set xmlDoc=CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("note.xml")

for each x in xmlDoc.documentElement.childNodes
  document.write("<b>" & x.nodename & ":</b> ")
  document.write(x.text)
  document.write("<br />")
next

</script>

-DNG

>for each x in xmlDoc.documentElement.childNodes
To answer op's question, it's this.
[tt]for each x in xmlDoc.selectNodes("/data/page[@id='2']/*")[/tt]

 

[stinkybee]

that example doesn't select the nodes within an element based on a specific id.

In my example I need to select everything between

<page id="1">
....other elements
</page>

That means all of the child nodes of the page node that has an id of 1

thanks tsuji, that sounds a bit more like it. By the way my last reply was to the post before yours

 

[stinkybee]

Whilst we are at it, can you tell me how to get the actual "id" value for all of the "page" nodes in my example xml code.

 

[tsuji]

Do this to get to the essential.
[tt]
for each x in xmlDoc.selectNodes("/data/page[not(@id = ./preceding-sibling::*/@id)]")
response.write x.getAttribute("id") & "<br />"
next
[/tt]

 

[stinkybee]

getting this error

Expected token ')' found ':'. /data/page[not(@id = ./preceding-sibling-->:<--:*/@id)]

 

[tsuji]

Is it a cut-and-paste that produces that error? There is no line break and no spurious space in the path except surrounding "=".

 

[stinkybee]

I did cut and paste but there is no line break and the only spaces are around the "=

 

[tsuji]

I would check for other reason for the error to turn up. I make a test case and it works fine.
