XML Search

Re: XML Search

XPath is pretty versatile. Any recurrsive method you might write should be
able to be implemented as an XPath expression, but run faster through XPath.
Can you give us an example, maybe someone could give you a snip to try out.

Re: XML Search

GetElementsByTa gName is one way to do it.

Re: XML Search

Hi Richard,

Thanks for your response but it was kind of general. As far as, I know
it works for XML TagNames but I'm looking for data which are in any place of
an xml file not any tag name. Let's say I have an xml file as below and my
program should find any thing like "#19384A" or "center" in below code. Does
the "GetElementsByT agName" works for this too ?

<?xml version="1.0"?>
<Form SurveyName="emp ty" SurveyID="1" StyleUsage="URL "
xmlns=http://www.yahoo.com SurveyProgramme r="ramsin" DateTime="2/12/2004
5:00:54 PM">
<Params>
<BackgroundColo r>#19384A</BackgroundColor >
<LinkColor>#fff fff</LinkColor>
<VisitedLinkCol or>#ffffff</VisitedLinkColo r>

<Header><tab le width='600' cellspacing='0' callpadding='0' border='0'

</Params>

</Form>

Thanks

You could use an XPath expression like the following to achieve this:

//*[contains(text() , '#19384A') or contains(text() , 'center')]

Just pass that to SelectNodes and you should be set.

Good luck,

Re: XML Search

Hi Derek,

Thanks for your response but what you said it's imposibile since
SelectNode() works for nodes not data or string embedded among nodes.

Re: XML Search

Hi again Derek,

I liked your idea but I tried it on below xml code. Please if you get a
chance try it maybe there is something that I'm doing wrong! When I ran

//*[contains(text() , 'b1') or bbb the an excpetion error coems up and
compalins about DataSet!

Any idea ?

- <AAA>

<BBB id="b1" />

<BBB id="b2" />

<BBB name="bbb" />

<BBB />

</AAA>
