We have been bitten by severe memory leaks in our project.
While having a dry run of one of the components code. I came across the following. This looks like a sure shot memory leak to me. Because of the fact that we are not doing a VariantClear().
Please confirm.
<<
try
{
IXMLDOMSchemaCollection2Ptr m_pSchemaCache;
hr=m_pSchemaCache.CreateInstance(__uuidof(MSXML2::XMLSchemaCache60));
if (SUCCEEDED(hr))
{
hr=m_pSchemaCache->add(szNameSpace_in, szSchemaFilePath_in);
if (SUCCEEDED(hr))
{
VARIANT varValue;
varValue.vt = VT_DISPATCH;
varValue.pdispVal = m_pSchemaCache.GetInterfacePtr();
m_pSchemaCache.AddRef();
m_pDOMDoc->PutRefschemas(varValue);
}
else
{
this->m_errorCode=ERR_XML_DOC_SCHEMA_ADDITION_FAILED;
return FALSE;
}
}
else
{
this->m_errorCode=ERR_XML_DOC_SCHEMA_INSTANCE_CREATION_FAILED;
}
}

(string-length(normalize-space($Curnode/@*[position()=7])) != 0)*($MsgLength + 5)
What will the above expression return if normalize-space($Curnode/@*[position()=7]) returns "0020100101".
What will (string-length("0020100101")!=0) return true,1,or stringlength???

Hi All,
I have a XML string with me in the format
<row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SEQNO>6</SEQNO>
<B_CO_CD>H</B_CO_CD>
<B_AREA_CD>K</B_AREA_CD>
</row>
the XML tags are taken in an actual string variable and then I need to find a particular tag and get its value to actually set that value in a dataset column that corresponds to this tag.
How can I do this ??
Pls guide me.. I need to give demo on this..Pls Pls

 Hi Omkar,
find below the code to get value in a particular tag.
System.Data.DataSet ds=new DataSet();
ds.ReadXml("D:\\MY_WORK\\ssis projects\\Executessis\\WindowsApplication1\\XMLFile1.xml");//here set your xml file path
int i=ds.Tables[0].Columns["SEQNO"].Ordinal;//getting the position of the column/tag
string s=ds.Tables[0].Rows[0].ItemArray.GetValue(i).ToString();//getting the actual vlaue inside the tag
Tell me if it will not work...

Hi,
I have a directory containing loads of xml files that change regularly. To generate a list of all the files in the directory i use this code:
Sub Page_Load(sender as Object, e as EventArgs)<br />
If Not Page.IsPostBack then<br />
Dim dirInfo as New DirectoryInfo(Server.MapPath(""))<br />
repeater.DataSource = dirInfo.GetFiles("*.xml")<br />
repeater.DataBind()<br />
End If<br />
End Sub
I then display this information in a asp repeater. Currently it lists the filename and size and when the document was last edited.
I wish to extend this concept to allow me to display the 'title' element of each xml file alongside the filename in my asp repeater. I know how to extract the 'title' from a static list of xml files by explicity binding to each one, but i dont know how to do this 'on the fly' with the xml files in my generated list. I hope that made relative sense to somebody.
Thanks alot.
Colm.

I have, for example, a variable $title accepting value (a string with value "title") from a text box .
Then I want to use this string to make reference to an element when I try to use a template that accepts a parameter as a node set.
<xsl:call-template name="show-items">
<xsl:with-param name="text" select="$title"/>
</xsl:call-template>
My xml is like this
<book>
<lang>english</lang>
<title>XML Basics</title>
<content>
......
</content>
</book>
but it does not work. The title accepted in the template "show-items" is not "XML Basics" but "title".
Please help!!!!

What you want to do is pass parameter "text" in "show-items" template with value "XML Basics" in it???
Try
<xsl:with-param name="text" select="/book/title/text()"/>
|
|
|
|
|
I want to use like
<xsl:with-param name="title" select="/book/$title">
but it doesn't work. It is said that a node set is needed, while the value of $title is 'title' (a string) not the title element, the "//book/title" one, the child node element of the book.
All I have now is a string with the value is the name of that element, and I want to use this name, translate it into a real element and then use that element.
Can I do that?

I help a small structure below
<jokes>
<joke>
<cat>poem</cat>
<title>ABC</title>
<content>
...
</content>
</joke>
<joke>
<title>123</title>
<content>
...
</content>
</joke>
</jokes>
As you can see, the values for <cat> is "poem" and "normal", for example. But I would like to make it like, when the <cat>poem</cat> appears, it means, the joke is in poem. But if the <joke> does not have <cat> or it has a empty pair <cat></cat>, the type of that joke is considered to be "normal".
How can I check to see if a tag is empty or not present?

You can test for the presence of a tag with XPath by just writing the tag name: //joke/cat This selects all <joke> tags that have a child <cat> tag. This selects all <cat> tags that are children of a <joke> tag. To test the actual contents of the <cat> you'll need other XPath functions (I just know basic XPath so I don't know the functions by heart, check out the docs)

No, that would select the "cat" elements not the "joke" elements.

 I was thinking the right thing, but explained it backwards.
|
|

The response above is correct. You can also use the boolean XPath function to determine if a tag is there or not:
/jokes/joke[boolean(cat)] would select all the joke nodes that contain a cat child element
/jokes/joke[not(boolean(cat))] would select all the joke nodes that don't have a cat child element

u can also compare value for that by using a query using XPathNavigator

Hi I need to merge several versions of xml documents which contain different data. I can't just append one document to another, instead it need to substitute elements which are the same (meaning having same tag in a hierarchy). One file will have higher precedence than the other and would substitute the data of the other one if same tag. I think an example would explain better than words.
<?xml version="1.0"?>
<!-- Old version, low precedence -->
<movies>
<movie name="Snakes on a Plane">
<director>David Ellis</director>
<year>2006</year>
<rating>M</rating>
</movie>
<movie name="The Descent">
<rating>R</rating>
<year>2005</year>
<director>Neil Marshall</director>
</movie>
</movies>
<?xml version="1.0"?>
<!-- Newer version, higher precedence -->
<movies>
<movie name="Snakes on a Plane">
<director>David R. Ellis</director>
<country>USA</country>
<rating>R</rating>
</movie>
<movie name="Finding Nemo">
<rating>G</rating>
<year>2003</year>
<director>Andrew Stanton</director>
</movie>
</movies>
<?xml version="1.0"?>
<!-- Merged version -->
<movies>
<movie name="Snakes on a Plane">
<director>David R. Ellis</director>
<year>2006</year>
<rating>R</rating>
<country>USA</country>
</movie>
<movie name="The Descent">
<rating>R</rating>
<year>2005</year>
<director>Neil Marshall</director>
</movie>
<movie name="Finding Nemo">
<rating>G</rating>
<year>2003</year>
<director>Andrew Stanton</director>
</movie>
</movies>
Notice in the merged version that for example director for Snakes on a Plane been updated and country added to same movie. Is there any way to do this using standard tools, like C#/.NET or SQLServer 2005 or some other library/product? Or do I need to implement this myself? Thanks for any pointers, Patric

One way to manupulate XML in this fashion would be to use the System.XML.XmlDocument and the XML DOM that it represents. There is information everywhere about using XML DOM. It comes in real handy so you may as well bite the bullet and get familiar with it.
