Thanks

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
