The second hit from google states that "Libxml2 is known to be very portable, the library should build and work without serious troubles on a variety of systems (Linux, Unix, Windows, CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, ...)" The XML C parser and toolkit of Gnome - libxml[^]
If you mean that you want to write your own XML parser that will be a very challenging task and most probably no one here can give you complete code for this. Your best bet would be to take a look at the sources of the available parsers to see how they tackle the problem.

If memory serves well there are some articles... At least one XML parser in C++ - probably portable to linux.

Hi,
I want to create a XSD schema to use for validating XML files like the following:
top>
top>
top>
top>
/top>
link> link> mid>
mid>
/top>
top>
bottom>
/top>
/top>
A "top" element can contain any number of "top" elements or any number of "link" elements or any number of "mid" elements. A "top" element can contain only one "bottom" element and no other element if it contains a "bottom" element. A "link" or "mid" or "bottom" element cannot contain any elements.
Any advice, please help?

Not tested, but should be at least a good starting point:
<?xml version="1.0" encoding="utf-8" ?>
<xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/XMLSchema.xsd"
xmlns:mstns="http://tempuri.org/XMLSchema.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="link">
<xs:complexType></xs:complexType>
</xs:element>
<xs:element name="mid">
<xs:complexType></xs:complexType>
</xs:element>
<xs:element name="bottom">
<xs:complexType></xs:complexType>
</xs:element>
<xs:element name="top">
<xs:complexType>
<xs:choice>
<xs:sequence>
<xs:element ref="mstns:bottom"></xs:element>
</xs:sequence>
<xs:sequence>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element ref="mstns:top"></xs:element>
<xs:element ref="mstns:link"></xs:element>
<xs:element ref="mstns:mid"></xs:element>
</xs:choice>
</xs:sequence>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:sche

Or even simpler...
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:complexType name="top">
<xs:sequence>
<xs:element name="top" type="xs:string" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="link" type="xs:string" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="mid" type="xs:string" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="bottom" type="xs:string" minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:element name="top" type="top" />
</xs:schema>

This doesn't cover the requirements that a "top" element can contain only one "bottom" element and no other element if it contains a "bottom" element.

True, didn't realize that was a requirement. I guess choice is the only valid approach.

i want to append data to <canada>
.....</canada>
Pls suggest

ImportRow is a DataTable method. If you are talking about XmlDocument, you can use the ImportNode method:
using namespace System;
using namespace System::Xml;
int main(array<System::String ^> ^args)
{
String^ srcXml =
L"<country>"
L"<canada>"
L"<lakes>yyyy</lakes>"
L"</canada>"
L"</country>";
XmlDocument^ srcDoc = gcnew XmlDocument();
srcDoc->LoadXml(srcXml);
XmlNode^ srcNode = srcDoc->SelectSingleNode(
L"/country/canada/lakes");
if (srcNode == nullptr)
{
Console::WriteLine(L"'lakes' node not found!");
return -1;
}
String^ destXml =
L"<country>"
L"<india>"
L"<states>1</states>"
L"<states>2</states>"
L"</india>"
L"<america>"
L"<value>xxx</value>"
L"<value>xxx</value>"
L"<value>xxx</value>"
L"</america>"
L"<canada/>"
L"</country>";
XmlDocument^ destDoc = gcnew XmlDocument();
destDoc->LoadXml(destXml);
XmlNode^ importedNode = destDoc->ImportNode(srcNode, true);
XmlNode^ destNode = destDoc->SelectSingleNode(
L"/country/canada");
if (srcNode == nullptr)
{
Console::WriteLine(L"'canada' node not found!");
return -1;
}
destNode->AppendChild(importedNode);
Console::WriteLine(destDoc->OuterXml);
return 0;
}

Hello,
I'm writing a web service that reads an XML from the web but this XML has some special characters that messes the reading method of the XmlReader and i can't find a way to resolve it.
here is the XML example im trying to parse to a datatable
<br />
<?xml version="1.0" ?><br />
<gsmrs_teams last_generated="20070428013954"><br />
<team team_id="2015" team_logo="true"><br />
<type>Club</type><br />
<br />
ETC.
the error looks like that:'>' is an unexpected token. The expected token is '"' or '''. Line 2, position 29.
My other Q is how can i read the output stream of the browser. Meaning how can i get the text equivalent to copy paste that i would do inside the browser text, but with asp.net methods (only text with no tags).
I want to Read text inside HTML tags.
Thanks,
Leo

The browser cannot file the document with that pathname. If you are accessing the file locally, then make sure this is the correct pathname. If you are accessing the file via HTTP, make sure the pathname is a relative or absolute URL.

hi guys,
I have failed to get a node set based on dates.
i have a simple xml
HTML Code:
<pre><code><PUBS>
<PUB>
<FIRSTINS>2006-12-08</FIRSTINS>
<LASTINS>2006-12-10</LASTINS>
</PUB>
</PUBS>
<PUBS>
<PUB>
<FIRSTINS>2004-12-08</FIRSTINS>
<LASTINS>2006-1-17</LASTINS>
</PUB>
</PUBS>
<PUBS>
<PUB>
<FIRSTINS>2007-12-08</FIRSTINS>
<LASTINS>2007-12-09</LASTINS>
</PUB>
</PUBS></code></pre>
in my xslt
HTML Code:
<pre><code><xsl:for-each select ="//PUB[FIRSTINS < LASTINS]">
..do some thing
</xsl:for-each></code></pre>
this always fails for me both less and greater than

If <Object> is your document node (topmost node) then your XPath should be: xxPath = "/Object[@name='" & LCase(menu11.Name) & "']"

I grabbed the following .xml and .xsd files from an online tutorial, and tried to import them into SQL Server by using XML Source. I want to be able to import ALL the data; however, the simpleType elements under the root <shiporder> are all missing from the XML source, e.g <orderpersion>. The root element, including any attributes from the root element are also missing...e.g <shiporder orderid="889923"
How can I import these missing fields? The .xml and .xsd files are below.
Any help will be greatly appreciated. Thanks.

Hi!
i am storing the user defined URL in XML file by using C#. I am storing that URL inside the tag as InnerText.
if i store the URL "http://www.google.com" it works perfectly, but when i try to store the URL "http://www.google.com/search?hl=en&q=abc" it corrupts the XML file and gives error "A semi colon character was expected."
can anybody tell me what is the reason behind this error...?
Thanks,
Regards,
Affan Ahmad Toor

Hi
I am quiet sure that the & is the error because it is a special sign in XML. If it also doesn´t work than i might suggest the ?.
Thats the two possabilities.
Hope i helped.

|
|
|
|
Thanks for reply,
i checked the & sign as you suggested. You was rite, the error was because of the & sign.
Looking forward for more help from you in future...
Thanks again...
