Xml refers to non existing parent - NO Answer in other subj

I keep getting the xml refers to non existing parent and incorrect XML. The XML is correct, because I tested it with Poster and with the browser and validator. What am i missing?

This is my XML (it passes when I send it by itself):

<tree id="0">
<item text="testing" id="t899888" open="1" im0="gobe.png" im1="green_button.png" im2="globe.png" im5="accept.png" aCol="green" call="1" select="1">
<item text="gr_11444" id="gr_11" open="1" im0="accept.png" im1="up.png" im2="down.png" aCol="blue">
<item text="011691000157100" id="k1hi6ae6p6b5912iv7q1a96if0_0" checked="1">
<userdata name="deviceID">sgdemo01</userdata>
<userdata name="imei_num">011691000157100</userdata>
</item>
<item text="imei_1000151954" id="k1hi6ae6p6b5912iv7q1a96if0_1" checked="1">
<userdata name="deviceID">sgdemo03</userdata>
<userdata name="imei_num">imei_1000151954</userdata>
</item>
</item>
</item>
</tree>

This is how I call it:

		var tree = layout.cells("b").attachTree(0);
		tree.setSkin('dhx_skyblue');
		tree.setImagePath("dhtmlx/imgs/csh_bluebooks/");
		tree.EnableDynamicLoading = true;
		tree.enableCheckBoxes(true);
		tree.enableThreeStateCheckboxes(true);
		tree.loadXML("db/location_xml.php?xmlType=tree");

I have Debug ON and this is what It gives me:

Not an XML, probably incorrect content type specified ( must be text/xml ), or some text output was started before XML data
Loading: db/location_xml.php?xmlType=tree

I had that error when I took out the <?xml version='1.0' encoding='iso-8859-1'?> from the top of my xml. I knew I had a problem when the sample xml from the dhtmlx site would not work without it.

I am trying to get xml containing google map coodinates from a java servlet using ajax and build the tree with it. I usually only do java so this is a pain.

Best of luck!

Thanks Thomas, but when you put it back, did it work? For me it doesn’t even work with it.

#4

I have Debug ON and this is what It gives me:
According to debug, xml request return error 404 page
Be sure that php script is really exist in the specified location.

#5

PHP script does exist. The data itself is bad. Any other ideas?

#6

The above log states 404 error
If that problem was resolved, and message still appears - it possible that the top level tag has incorrect id

Normally it is

where 0 - id to which loaded list of items will be appended ( 0 - virtual root item )

#7

The id is explicitly assigned 0. when I run the url directly with Poster I get a good result of xml.

#8

If you run url directly - did browser colors is as xml or shows as plain text

There are two possible problems with xml parsing which may lead to incorrect xml processing

  • incorrect content-type, must be text/xml
  • some whitespaces before <?xml tag

in both cases xml may look as valid one, but browser will not be able to parse it

#9

The XML is fine. I even use the same XML to render the grid.

#10

If issue still occurs for you - please provide any kind of sample or demo link where it can be reconstructed.
