Help with RegEx?

Copy linkTweet thisAlerts:
Jun 16.2006

Hi all,

1)
———————————————————————-

var str = “<td charts=”ExcelGraph1,ExcelGraph2″ formula=”1″ standard=”” style=”border-right: 1px solid rgb(228, 227, 201); border-bottom: 1px solid rgb(228, 227, 201); background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Arial; font-size: 10pt; text-align: left;” class=”cell” id=”cell-4-2″ cellvalue=”1″><div class=”nowrap”>1</div></td>”;

From the above string, I need to replace the charts attribute with “” using RegEx, I tried like this,

str = str.replace(/charts.*ExcelGraph.*s/g, “”);

But I couldn’t find any solution, can anyone help me with a better Solution?

str = “<table><img style=”display:none;” class=”charts” id=”ExcelGraph1″ src=”/test.chart/jfreechart2999.png” height=”200″ width=”300″>
<img id=”spacer” src=”spacefr.gif”><img style=”display:none;” class=”charts” id=”ExcelGraph2″ src=”/test.chart/jfreechart2930.png” height=”200″ width=”300″ ><table></table>”;

From the above string, I need to remove the img tags with id starting with “ExcelGraph” using RegEx, I tried like this,

str = str.replace(/<img.*id.*ExcelGraph.*>/gi, “”);

But I couldn’t find any solution, can anyone help me with a better Solution?

Thanks & Regards,
Suresh.

str = str.replace(/ charts="[^"]+"/, "");

...or...

str = str.replace(/ charts="ExcelGraph[^"]+"/, "");

@KorJun 17.2006 — Will I be excused, but I feel that if you had have used DOM methods to create your elements (table, tr, td, img) it would have been extremely easy to change elements' attributes' values later.

On the other way, it looks to be that your HTML elements in your strings are not correctly written. A table must have row/rows and cell/cells. A sequence <table> - <img> - </table> looks incomplete and incorrect to me.

@ssureshkumarauthorJun 17.2006 — Hi Kor,

Thanks for your response.

I have given only the sample htmlstring.

Actually, its a large html file. From that I have to remove the image tags.

Hope u understand.

Regards,

Suresh.

It is the same concept/technique as the one I've already done for you. Figure out what I did for that one and you can apply that knowledge to the second one.

@ssureshkumarauthorJun 17.2006 — Hi,

thanks for your help.

I solved the problem.

Here is my solution to remove the corresponding image tag,

replacedValue = replacedValue.replace(/<img.*id="ExcelGraph[^"]+"[^<]+/gi, "");

It produced me the correct result.

I need to clarify, whether this solution works in all the conditions.

Thanks for any response,

Regards,

Suresh.

Yeah, so tell me... When you receive the entire HTML source of a page as a string of text, and you wish to selectively modify parts of that text string... How would use the DOM to make that modification to the text string? The only way I know of is to have the browser first render the unmodified text and, then, use the DOM (after the fact) to modify the rendered HTML. I don't think that is as good of a solution -- though it would certainly work just fine (harder to find the desired elements, though).

@KorJun 17.2006 — make it an XML from the begining
Copy linkTweet thisAlerts:
@phpnoviceJun 17.2006 — Now you're changing the whole setup. This would cause a major conversion of all existing HTML-only source to XML. Not very efficient. :rolleyes:

@KorJun 18.2006 — Yes, I know, it is another discution. You are right, as long as ssureshkumar has already a string...
