Adding Attributes to XML node using VBA
-
Hi, Code is working fine. I tried by removing on error resume next. Problem is that if i add attribute to that tags which is like Attribute="1,1,1,..." then it is giving error. I am not sure the way to keep the attributes there. Or is there any way after generation of an xml, can we open that xml file and add attributes to that? Regards, Priya.
I had a think about what i had written, and no it won't throw an excpetion, All that will happen is MatchAll will always be False so that code is effectively doing nothing (because 1 or higher is always greater than 0). All you are doing is generating a bunch of strings and bolting them altogether. After you generate the xml and the function exits, have you had a look at the XML file to see what it looks like?

In that case all you are doing now then is adding the attributes to the node. Create a helper function like;
getNodeAttributes(node as integer) as stringIn it, test node to see which attributes you need to build, then return them in the function, if the node does not need any attributes, then return an empty string. Then modify;strXML = strXML & "<" & Nodes(t) & ">"tostrXML = strXML & "<" & Nodes(t) & getNodeAttributes(t) & ">"simples........Dave Don't forget to rate messages!

Waving? dave.m.auld[at]googlewave.comHi Dave, Thanks lot. I tried adding the funtion like :
Function getNodeAttributes(node As String) As String
Dim str_att As String
If node = "Policy_Years" Then
str_att = "Attribute=" & "1,1,0,1,16711680,2,0,0,1,16711680,0,0,0,0,0,0.5,10,Arial,1"" Attribute2="""
End If
End Functionand also changed
strXML = strXML & "<" & Nodes(t) & getNodeAttributes(Nodes(t)) & ">"
Just tried assigning attribute to only one node. But I am not getting any in the output for the tag Policy_Years. Please Help.. Regards, Priya.

Of course you wont, your passing across the node index not the node name;

Hi Dave, Still no its not showing... :-( Is there any other way to implement this? Regards, Priya.
Well i fail to see what you are doing wrong. Don't give in! At the end of the day, all you are doing is simple string manipulation, it doesn't matter if it is in XML format or any other text based format. If your output XML file shows the attributes after your text generation then it is working. If your output does not show the attributes, then your code is wrong. You maybe need to start putting in extra breakpoints, debug.print(), or message boxes statements through your code until you can find out what is going on. everytime you generate a node or an attribute use these statements to see what the string is before and after. That way you will be able to see what you are getting versus what you are expecting at each stage. This is basic troubleshooting. As i have stated before your function is way to big, and you really need to restructure and break out lots of smaller helper functions which can then be called to piece the final text XML string. As i say, this is basic string manipulation, so something obvious is wrong somewhere!

Waving? dave.m.auld[at]googlewave.comHi Dave, Thanks really!... I am planning another way. TO open the xml file generated and then adding attributes to elements. If you dont mind can you please give me example for this. Yes i remember, you have sent me the reference to DOM Methods for implementing this. But at this point of time with so much stress i cannt think of anything and this have to completed asap i do not have even hours of time...pls pls help.. Thanks in advance..reply if ur online Regards, Priya

No that is not the way to go, you are making things harder for your self, you will then have to read, parse, inject , save strings. You have already got a function that generates a valid XML file, so you are 99% of the way there. Have you done what i have suggested with regards to breakpoints and or debug statements? strategically place them in your code, and you will see where the attributes you have added are then disappearing (if they are disappearing at all that is). Also, in the previous message did you replace both instances of the code where you inject the attribute function? you have 2 lines that do it depending on the state of some value. Did you please a debug statement in your attribute function to prove it is being called? Did you add a debug.print statement to see what it was adding to the string?

Waving? dave.m.auld[at]googlewave.comDave, <pre attribute="vb"> Yes I did debut and breakpoints. Actually I have to keep getNodeAttribute function in the first set not in the second set. I examined that. During call of the above function i print the var in immediate window. it is printing like : Attribute=1,1,0,1,16711680,2,0,0,1,16711680,0,0,0,0,0,0.5,10,Arial,1" Attribute2=" but when it go back to the main line from where are calling the function it is not returning anything..

It looks like you are missing quotes from the output string. As you already know, you have to increase the number of quotes if you want to add quotes to the output, you are only doing this in some of your code.

Look at the code after "Attribute=" the opening value only has a single double quote, which will result in Attribute=1,1,....etc. and not Attribute="1,1,...etc. yet at the end you correctly add the extra quotes. you can always consider user Char(34) in you string generator so you can see where you want to add the quote to the output e.g. (34 is the ASCII value for a double quote, look at asciitable[^])
str_Att = "Attribute1=" & chr(34) & "1,1,0,1,16711680,2,0,0,1,16711680,0,0,0,0,0,0.5,10,Arial,1" & chr(34) & " Attribute2=" & chr(34) & "some value" & chr(34)Dave Don't forget to rate messages!

Hi Dave, Yes I have noticed that and changed...but why the function is not returning anything. Regards, Priya.
Because you haven't returned a value yet! remember you need to set the function name to the value you want to return;
Function getNodeAttributes(node As String) As String
'Do whatever you need
'Return the output to the caller
getNodeAttributes = str_attEnd Function
