Re: Microsoft VBScript runtime error '800a01a8' Object required

10-Sep-09 4:38

Dear All,
I have a combination of classic ASP page and asp.net pages in the application. I am getting this error "Microsoft VBScript runtime error '800a01a8' Object required" on a asp page.
The error is coming from this code:

sRawHtml = Request("h_RawHTML")

Set xd = Server.CreateObject("MSXML2.DOMDocument")
Call xd.loadXML(CStr(sEncrypteXML))

set xel = xd.selectSingleNode("//WebSiteInformation")
xel.setAttribute "Site_HTML", CStr(sRawHTML)

Please tell me if I have written something wrong.

Thanks,
SP

Which line gets the error ? Is the MSXML2.DOMDocument class present ( I think it's part of IE, so it should be, but that seems to me to be what the problem is ).

Hi, the error is on the last line (xel.setAttribute "Site_HTML", CStr(sRawHTML)).
this is working for some HTML code passing thru sRawHTML; and not working for some other HTMLs

And is it possible you could post examples of working and not-working HTML? Or is it secret?

OK, well, that's easy. xel is sometimes null. I notice you don't write code to check if it is.

Hi i had been using XercersDomParser for parsing the XML file in C++

I am not familiar with XML. In the follwing XML file

<?xml version="1.0" encoding="UTF-8"?>
<Locomotives>
<Locomotive xmlns="http://localhost:8080/source/schemas/locomotive.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://localhost:8080/source/schemas/locomotive.xsd http://localhost:8080/source/schemas/locomotive.xsd">

<LocoRunNumber>UnReg</LocoRunNumber>
<LocomotiveGPSData>
<SampleTime>2008-07-13T13:37:33</SampleTime>
<Latitude>-32.86693333</Latitude>
<Longitude>151.75333333</Longitude>
<Speed>-1</Speed>
<Direction>-1</Direction>

<TrackNumber>87</TrackNumber>
</LocomotiveGPSData>
<Events>
<Alarms>0</Alarms>
<Faults>0</Faults>
</Events>
</Locomotives>
Eventhough i can traverse through XML file through

DOMTreeWalker but can't get idea to store Values in a strucured <list>

the structure look like this

typedef struct

{

Loco_Id LocoId ;

string /*DateTime*/ SampleTime ;

float Lattitude;

float Longitude;

float Speed ;

float Direction;

int KmPostPosition;

int TrackNumber;

int Alarms;

int Failures ;

}LocoDetails

Can any one tell how to access the value from the XML file and store to a list

Stuart Dootson5-Sep-09 2:52

There are a lot of ways to do it - here's some suggestions:

The DOMTreeWalker lets you set up a node filter. You can set up a filter to accept all element nodes whose tag is Locomotive. That means that each call to the DOMTreeWalker's nextNode method will step to the next Locomotive element. For each of these, you iterate through the found element's child nodes. Each child's tag name indicates which struct memeber they relate to, while the child's text node is the value that you'll convert to the correct type using string conversion functions like strtol.
From the root node, apply an XPath of "//Locomotive". That'll get you all the Locomotive elements, which you can process as above.
Get a DOMElement for the root element of the XML document. Use the getElementsByTagName method to retrieve all descendent nodes with the tag naem Locomotive. Process each node as indicated above.

Hope that helps you!

DOMElement* elementRoot = domDocumet->getDocumentElement();
DOMTreeWalker *walker =domDocumet->createTreeWalker(elementRoot,DOMNodeFilter::SHOW_ELEMENT,NULL, true);
DOMNode *pCurrent = NULL;
for ( pCurrent = walker->getCurrentNode();pCurrent != 0; pCurrent = walker->nextNode() )
{
if(pCurrent->getNodeType() == DOMNode::ELEMENT_NODE)
{
char *str = XMLString::transcode(pCurrent->getNodeName());
if(!strcmp(str,"LocoId"))
int i=0;
//myDetails->LocoId = XMLString::transcode(text->getNodeValue());
if(!strcmp(str,"Latitude"))
//myDetails->Lattitude = XMLString::transcode(text->getNodeValue());

XMLString::release(&str);
}
}
Could you please tell me where to set the filter as Locomotive

you also mentioned "From the root node, apply an XPath of "//Locomotive "
what does it mean

Thanks

Set the filter in the createTreeWalker method call.

Using an XPath[^] library such as Xalan[^] or XQilla[^], you apply an XPath evaluator class to the DOM. That will give you an iterator that'll go through the nodes that match the XPath expression you gave to the XPath evaluator.

Read up on XPath - it's a very useful tool to know how to use.

If you would like an answer to this:

0) You need to use the VB .Net forum
1) Please don't double post, be patient and keep your posts together so people can see what has been suggested
2) You will need to show what you have already tried, and where it goes wrong. People won't write the code for you
3) Give as much detail as possible. You seemed to be on the right track with your last post, but we don't know how you're storing your XML in your code, how you want to store it on the disk, etc.
