Need to Hide <a> Tag that is generated automatically from other source_问答_开发者

I need to put RSS viewer web part that shows Stock Quotes for JPMorgan Chase.

RSS feed that I found for that is : http://www.quoterss.com/quote.php?symbol=JPM&format=0&uid=1280868448 but his feed also retrives unnecessary links such as FaceBook cheat codes, Iphone cheat codes ... I want to hide those unnecessary links for the cheat codes.

XSLT for RSS viewer web part having above mentioned feed is provided below.

                </xsl:when>
                <xsl:otherwise>
                     <xsl:value-of select="rssaggwrt:MakeSafe($Html)"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:template>

</xsl:stylesheet>

From the above XSLT I was able to figure out that HTML is generated automatically, that is done by

        <xsl:template name="GetSafeHtml">
            <xsl:param name="Html"/>
            <xsl:choose>
                <xsl:when test="$rss_IsDesignMode = 'True'">
                     <xsl:value-of select="$Html"/>
                </xsl:when>
                <xsl:otherwise>
                     <xsl:value-of select="rssaggwrt:MakeSafe($Html)"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:template>

If I am going in the right direction, if HTML is generated automatically, I will not be able to hide those unnecessary links using XSL. So I tried to do that using JQuery.

HTML that is generated automatically is as follows.

<table border=0 cellspacing=0 cellpadding=1 width=150><tr><td bgcolor="#000000"> <table border=0 cellspacing=0 cellpadding=0 width="100%" class="pq_all"> <tr bgcolor="#DDDDDD"><td width="100%" align=CENTER colspan=3 nowrap> </td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;Last </td> <td width="40%" nowrap align=right>45.74</td></tr> <tr bgcolor="#DDDDDD"><td width="100%" nowrap>&nbsp;Change </td> <td width="40%" nowrap align=right><font color="#409940">+1.18</font>&nbsp;</td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;% Change </td> <td width="40%" nowrap align=right><font color="#409940">2.65%</font>&nbsp;</td></tr> <tr bgcolor="#DDDDDD"><td width="100%" nowrap>&nbsp;Volume </td> <td width="40%" nowrap align=right>77445704&nbsp;</td></tr> <tr bgcolor="#EEEEEE"><td width="100%" nowrap>&nbsp;Last </td> <td width="40%" nowrap align=right>4:02pm&nbsp;</td></tr> </table> </td></tr></table> _<div><a href="http://cheatcodes.com/iphone/">iPhone Cheat Codes</a></div>_

I want to hide the link containing reference to the http:.//cheatcodes.com/iphone/ which is rendered as "iPhone Cheat Codes" in ITALIC. By using JQuery I tried

$('a[href*=http://cheatcodes.com]').hide()

...... but this doesnt work. I also tried to dig into it and when I tried to fetch the value of href tag using

alert($('a[href*=http://cheatcodes.com]')).attr(href)

JQuery shows me undefined as a result. Also the links for the cheat codes also get updated on daily basis ... only thing that I found is this portion of the URL remains same is: http:.//cheatcodes.com/... As per my understanding as the HTML is generated automatically JQuery is not able to hide that Anchor tag.

I am kind of stucked into this. If some one gives me light on the exact cause of the behaviour and the solution, I really would appreciate it. Also if some one knows about other RSS feed where I can get the stock quote for the JPMorgan Chase would be helpfull to overcome this issue.

Thanks, Dhaval

Did you try alert($('a[href*="http://cheatcodes.com"]')).attr(href)?
