dear all,


i am doing my project which need to convert xhtml to xml using xpath.
take for example, i need to collect the data from this td tag

code:
-<tr>
- <td align="left" valign="top">
  <img height="1" src="http://pics.ebaystatic.com/aw/pics/s.gif" width="10" /> 
  13-Jul-2005 13:26:47 IST 
  </td>
  </tr>



i used to like using

code:
tr[1]/td/img/text()


xpath expression to collect the data i want
but my problems is every webpage may contain different number of total of row, so without knowing the x number of row, i cannot specify in the tr[x],
is there any other way to do it?

any help is greatly appreciated

thank u

Sorry just cleaned up the path using square brackets like that can break in the board


Um is there something unique to that row? Without some form of identifier it's going to be hard to pull a specific row

If you are using XSLT why not use XSLT, that is what the <xsl:for-each/> loop or the <xsl:apply-templates/> is for.

If you put you XSLT in here I might be able to offer you further assistance in getting done what you need to get done, but the XPath without anything else is not going to give me enough to work with.

i am totally new to xslt and
i try with this xslt


code:
<xsl:template match="table[starts-with(normalize-space(tr/td[2]/span/b/text()),'User ID:')]">
		<xsl:for-each select="tr[$counter+1]">
		<buyer>
		<xsl:value-of select="td[2]/a/text()"/>
		</buyer>
		<price>
		<xsl:value-of select="td[3]/text()"/>
		</price>
		</xsl:for-each>
	</xsl:template>



but it only can get the first tr result, but what i want is after the for loop can get

code:
tr[1] , tr[2]



hope you understand what i mean :>

thank u

Your for-each looks fine if you lose the square braces, you then should be fine to match against every <tr>.

The match on your template looks really funky. I don't know how you are expecting to match XPath in the text of a bold tag in a span. If you are the HTML must be pretty crazy.

hi,


i sucessfully get the data, but is it possible to dynamically name the element tag name.

what i get:

code:
<buyer>
naveen71
</buyer>
<buyer>
sweetsam84
</buyer>



is it possible to make it like

code:
<buyer_$counter>
naveen71
</buyer>
<buyer_$counter+1>
sweetsam84
</buyer>



i try with this but get compiled error.
is there any way to name the tag by using variable?

thanks

You might be able to key off of the TR count.

<xsl:element/>

hi,

thanks for your suggestion. i try with this.

code:
<xsl:param name="counter" select="'2'"/>
........
..........
<xsl:template match="table[starts-with(normalize-space(tr/td[2]/span/b/text()),'User ID:')]">
		<xsl:for-each select="tr">
		
		<xsl:element name="$buyer">
		<xsl:value-of select="td[2]/a/text()"/>
                                <xsl:value-of select="$counter+1"/>
		</xsl:element>
</xsl:template>




but how come i fail to get the tag name printed out.
what i want is,

code:
<2>
value
3
</2>



and can i know whether the counter will keep track of the previous value in the for loop or always follow the default value as i always get the value for $counter+ 1 is 3,
i thought that it should be 3,4,5.....

thanks !!

I would do the following.

code:
<xsl:template match="your crazy table match">
  <xsl:for-each select="tr">
    <buyer>
      <name><xsl:value-of select="select the name"/></name>
      <number><xsl:value-of select="position()"/></number>
    </buyer>
  </xsl:for-each>
</xsl:template>



I am not testing this. It is a general idea, but it might fail.

Element names cannot start with a digit.

Use

code:
$counter+position()

or just

code:
position()

as WarMage said.

hi,

thanks for helping.
but for my data collection, i need to collect many buyer details.
so what i hope to have is like this:

code:
<buyer_name1>naveen71</buyer_name1>
<buyer_name2>sweetsam84</buyer_name2>



and i hope to generate the tag name dynamically, is it possible?

again, thanks for all of your helps.

code:
<xsl:element name="buyer_name{position()}">[element content]</xsl:element>


However, it would probably be better with a structure something like

code:
<buyer id="1">...</buyer>
<buyer id="2">...</buyer>

hi hi

thanks a lot~~~~~~
another problems here, for my for loop, i will get some unwanted value
and i try to use the <xsl:if> to help me

take for example, the first tr/td value is "a", but i want to disgard this
so i try with this

code:
<xsl:template match="your crazy table match">
  <xsl:for-each select="tr">
    <xsl:if test="name != a">
    <buyer>
      <name><xsl:value-of select="select the name"/></name>
      <number><xsl:value-of select="position()"/></number>
    </buyer>
   </xsl:if>
  </xsl:for-each>
</xsl:template>



my intention is wan to eliminate the buyer name 'a' , but what i got is all buyer name is eliminate and fail to get the buyer details.


thanks a lot!

hi,

thanks , but still cannot.

code:
<table>
<tr>
<td>A</td>
</tr>
<tr>
<td>B</td>
</tr>
</table>



i want to discard the "A"

so this is how my xsl code

code:
<xsl:for-each select="tr">
<xsl:if test="tdtext() != A">
		<buyer_name>
		<xsl:value-of select="td/text()"/>
		</buyer_name>
 </xsl:if>
</xsl:for-each>



so i should be able to get "B". but instead, i didnt get anything
it seem not it stop at the if statement there

thanks!!!!

hi hi, thanks so much

can i know whether xslt provide substring function?
take for example:


code:
- <tr>
- <td>
  <p class="plabelb">Shipping fee: $1.00</p> 
  </td>
  </tr>
- <tr>
- <td>
  <p class="plabelb">The seller has chosen the following shipping services:</p> 
  </td>
  </tr>



and i just want to compare the "Shipping fee" string
take for example:

substring( tr/td/p/text() ) = 'Shipping fee'
as the full string for tr/td/p/text() is Shipping fee: $1.00


thanks so much!

XSLT has a substring function, but what I think you're looking for is the contains function.

Some links on them: http://www.w3schools.com/xpath/xpath_functions.asp
