sum function and formatting

[oandie]

Hi there,

I am trying to sum some coordinates, afterwards I want to format them and display the issue.
I tried the following but it didn't work out.

Code: Select all

<xsl:template name="x">

				<xsl:variable name="x_sum" select="sum(xplan:position/gml:Polygon/gml:exterior/gml:LinearRing/gml:pos[substring-before(.,' ')])"/>

				<xsl:variable name="x_count" select="count(xplan:position/gml:Polygon/gml:exterior/gml:LinearRing/gml:pos)"/>

				<xsl:variable name="x_format" select="format-number($x_sum, '#')"/>"

				<xsl:variable name="x_rw" select="3400000"/>

				<xsl:variable name="x_ges" select="$x_rw*$x_count"/>

				<xsl:variable name="x_ges1" select="$x_format - $x_ges"/>

				<xsl:variable name="x_ges2" select="$x_ges1 div $x_count"/>

				<xsl:value-of select="$x_sum"/>

				

			</xsl:template>

The source looks like this:

Code: Select all

(...)

<gml:pos>3480252.383 5889479.27</gml:pos>

<gml:pos>3480289.585 5889464.571</gml:pos>

(...)

On the display it says that it is not a number, so I used "number" to convert it but it didn't work as well.

Maybe somebody could give me a tip..

cheers

I forgot to say that I want to summarize the first coordinates with the leading 3 and then the second with the leading 5.

Hi,

gml:pos[substring-before(.,' ')]

This selects the gml:pos nodes that have some content before a space character inside them, so it will not select the text that for the first number.
