You answered yourself. If you have XML, say <circle radius="10px" color="red" x="50" y="100" />, you just parse it with classes from System.Xml, and then use GDI+ ( System.Drawing ) to draw that circle. AFAIK there is no "native" XML-based format for GDI+ (WMF maybe, but that again isn't text format, but binary one).

Unfortunatley, it is a little more complicated than that. The XML is all text and the XSL is the layout for an Invoice which includes text, html and images. I have never used System.Drawing and new to .Net generally. Is there perhaps someway to convert the transformation output to binary and feed the binary stream to one of the System.Drawing classes?

I think I am finnaly understanding the problem. You don't need to output image from XSLT transformation, but you need to save that output (HTML with images etc.) as image, right? I think your best bet is 3rd party component... I don't know any way (not to mention easy way) how to convert HTML to TIFF image.

Exactly! I tend to agree, I cant find anything online (code) that is not a third party product. I have even tried converting the html output to binary then to tiff or bmp with not much success. Thanks for all our help, if I figure out a way, I will post it out for others to use...

hi,
I am facing a problem of inserting two sheets in an excel workbook as well as corresponding data in it using XML/HTML.
please tell me whether this can be done and if yes then can I have a sample code for the same.
thanks.

First modify your post and check "Do not treat <'s as HTML tags", then tell us HOW you tried to change text of node, and WHY you were unable to do it, possibly show what EXACTLY error message say.
thanks

am using datasets to write an xml output file. one of the requirements, is to "nest" within a "nested" element.
I was writing out using
With ds.Tables("Account")
.Columns("stateacctrecordid").ColumnMapping = MappingType.Element
<<<< NEED to Nest another data set at this Point>>>>
.Columns("businessname").ColumnMapping = MappingType.Element
.Columns("businesstype").ColumnMapping = MappingType.Element
.Columns("operationtype").ColumnMapping = MappingType.Element
.Columns("county").ColumnMapping = MappingType.Hidden
.Columns("Active").ColumnMapping = MappingType.Hidden
End With
But now within this nest I need to nest another data set after the column "Stateacctrecordid"
Any Ideas would be helpful

I am looking to edit an XSLT that has 2 nested for-each calls in order to group items based on the value of a subnode of each item.
The innnermost for-next processes each item for html display. I'm using choos-when-otherwise combo to check the position() for the current group. If the position = 1 it is displayed differently than the other items.
What I'd like to do is put the first item contents into an HTML table row and then put ALL of the remaining items for the current group into the next table row.
My problem is I can't put <tr> or <td> tags into the xsl:otherwise node because they are inserted for every item, and I can't seem to put the html tags outside the xsl:otherwise section or use conditions (position=2) because then the html tags don't match up and the xslt document won't validate.
I'm new to XSL and must be missing something... ideas anyone?
==================================================
<xsl:key name="items-by-category" match="item" use="category" />
<xsl:template match="rss/channel">
<xsl:for-each select="item[count(. | key('items-by-category', category)[1]) = 1]">
<xsl:for-each select="key('items-by-category', category)">
<xsl:choose>
<xsl:when test="position() = 1">
<tr><td>item output format style 1</td></tr>
</xsl:when>
<xsl:otherwise>
item output format style 2 - includes all remaining items in the group
but I want to put all of these into a single TD as above, not each one in a separate TD?
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:for-each>
======================================================

hi, you probably have to use <xsl:value-of select="<td>" > etc., you can't have malformed HTML literaly in XSLT.
ps. I write this from head so sintax is probably wrong, but I hope you get the idea.

Hi
I want to delete node from xml file
this is example of xml file
<audit_list>
<control_type>xxx
<control_group group="xxx1">
<control_sub_group sub_group="yyy1">
<activity>
<control_activity>zzzz</control_activity>
<comment>large</comment>
</activity>
</control_sub_group>
<control_sub_group sub_group="xxx2">
<activity>
<control_activity>ccccc</control_activity>
<comment>medium</comment>
</activity>
<activity>
<control_activity>bbbb</control_activity>
<comment>large</comment>
</activity>
</control_sub_group>
<control_group group = "xxx2">
<control_sub_grop sub_group = "">
.....
this is my command to delete node but I get some error that I can't solv
please help me?
I want to delete node <activity> which have text of <control_activity> = ........ (get from user)
Dim listname As String
If rdo_type1.Checked Then
listname = "audit_list.xml"
ElseIf rdo_type2.Checked Then
listname = "audit_list_application.xml"
End If
'==============
Dim objdomdocument, objxmldomnode, objelement, strxpath, objCurrNode

objdomdocument.async = False
objdomdocument.load(Server.MapPath(listname))

Dim a As Integer
For i = 1 To 50
t_attribute = objCurrNode.childnodes(i).getattribute("group")
If t_attribute = lst_group.SelectedItem.Text.ToString() Then
objCurrNode = objCurrNode.childnodes(i)
For j = 1 To 50
x_nodelist = objCurrNode.childnodes(j).getelementsbytagname("control_activity")
For a = 0 To x_nodelist.length

objCurrNode.childnodes(j).childnodes.item(a).removechild(objelement)
Exit For
End If
Next
Next
End If
Next
objdomdocument.save(Server.MapPath(listname))
thank you.

If you find a node you want to remove, then you need to do theNode.ParentNode.RemoveChild(theNode). Something like that, the syntax is not exactly right.

plase suggest me more, I don't understand
I can remove node <control_sub_group> by using command below
Dim listname As String
If rdo_type1.Checked Then
listname = "audit_list.xml"
ElseIf rdo_type2.Checked Then
listname = "audit_list_application.xml"
End If
'==============
Dim objdomdocument, objxmldomnode, objelement, strxpath, objCurrNode
objdomdocument = CreateObject("Microsoft.XMLDOM")
objdomdocument.async = False
objdomdocument.load(Server.MapPath(listname))
objCurrNode = objdomdocument.documentelement.firstchild
strxpath = "audit_list/control_type/control_group[@group = '" + lst_group.SelectedItem.Text.ToString() + "']/control_sub_group[@sub_group = '" + lst_subgroup.SelectedItem.Text.ToString() + "']"
objelement = objdomdocument.selectSingleNode(strxpath)
Dim i As Integer
Dim t_attribute As String
For i = 1 To 50
t_attribute = objCurrNode.childnodes(i).getattribute("group")
If t_attribute = lst_group.SelectedItem.Text.ToString() Then
objCurrNode.childnodes(i).removechild(objelement)
Exit For
End If
Next
objdomdocument.save(Server.MapPath(listname))
I think command strxpath = ....... it can get me a node <control_sub_group>
but now I want to delete node <activity> that use <control_activity> to be condition
I'm not sure if I want to delete node <activity> I can use strxpath or not/
or I should use another command?
please revise my syntax or suggest me more
thank you

Ah.. maybe you need to remove the inner child nodes before you can remove a node that has children of it's own ?
I was saying that if you use an XPath to find the actual node you want to remove, you can remove a node using itself as the point of reference, because there is a ParentNode property you can use to get the node one higher than the one you're at. That way, you don't have to search for nodes based on the node you want to remove being a child, but just search for the node you want.

command ---
strxpath = "audit_list/control_type/control_group[@group = '" + lst_group.SelectedItem.Text.ToString() + "']/control_sub_group[@sub_group = '" + lst_subgroup.SelectedItem.Text.ToString() + "']"
objelement = objdomdocument.selectSingleNode(strxpath)
command above I can use parentchild.removechild(objelement) but
command ---
strxpath = "audit_list/control_type/control_group[@group = '" + lst_group.SelectedItem.Text.ToString() + "']/control_sub_group[@sub_group = '" + lst_subgroup.SelectedItem.Text.ToString() + "']/activity/control_activity"
this command not specific activity that I want to delete the activity node that i want to delete it depend on control_activity.value
this command how can i specific node activity that have node <control_activity> xxxx </control_activity>
I'm not sure do you understand my problem,I'm sorry if I make you confuse
Thank you.

I admit that I am unlikely to read carefully the huge amount of code you posted. If you're wanting to remove based on the parent node, then you don't need what I suggested.
Perhaps if you explained what error you are getting, it would be easier to help you.

error message is
" Object variable or with block variable not set "

On to your code:
For j = 1 To 50
Why 50 ? Are VB arrays 1 based ? ( Nothing would surprise me ). This will give you an error if you have less than 50 elements, and not search them all if you have more
x_nodelist = objCurrNode.childnodes(j).getelementsbytagname("control_activity")
For a = 0 To x_nodelist.length
x_text = x_nodelist.item(a).firstchild.nodevalue
If you look at your schema, control_activity does not have any child nodes, which is why this blows up, with the error you describe.
If x_text = lst_activity.SelectedItem.Text.ToString() Then
objCurrNode.childnodes(j).childnodes.item(a).removechild(objelement)
and therefore, it won't even get this far.
Exit For
End If
Next

Thank you very much for your kindness, but I still can't solve my problem

Hi - I was just looking at your x-path - -
audit_list/control_type/control_group[@group = '" + lst_group.SelectedItem.Text.ToString() + "']/control_sub_group[@sub_group = '" + lst_subgroup.SelectedItem.Text.ToString() + "']/control_activity/activity
1) I notice that: you have "activity" as child of "control-activity" while your xml is the other way around: "control-activity" is the child of "activity".
2) if this is corrected - then to remove the activity node:
Something like this:
//first get all the nodes that have control-activity = to user input
dim contActNodes, contActNode, actNode
contActNodes=objdomdocument.selectNodes("//control-activity[.='user-input']")
for each contActNode in contActNodes
//parent node of control-activity is activity
actNode = contActNode.ParentNode
//to remove activity, you need to get to the parent of activity
actNode.PerentNode.RemoveChild(actNode)
next

I have a XML file eg
<Root>
<Data>SomeData</Data>
<Data>More ...<Data>
</Root>
I now need to add another Data Item , I'm using XmlTextWriter.
How can I open the file without parsing the XML and add another Data item ?
and avoid having multiple root items.
Im using Windows CE so XMLDoc is too expensive, and I would like to avoid seeking through the stream to find </Root>
Thanks

Is there a SAX implimentation on CE ? SAX is a model for passing through large documetns without loading them into memory.

Quick look at MSDN shows that there is SAX on CE.

So does XmlReader/XmlWriter.
