It is not clear what you want to achieve above. Your select expression 
../../svg:g[@title] looks at svg:g children of the grandparent element 
having a title attribute. If you want to output the title attribute 
value then you need ../../svg:g[@title]/@title.
As your SVG sample above does not have any g element with a title 
attribute I can't tell which expression you are looking for.

Also note that in XSLT 2.0 the xsl:attribute element allows a select 
attribute so you can shorten e.g.
   <xsl:attribute name="foo">
     <xsl:value-of select="bar"/>
   </xsl:attribute>
to e.g.
   <xsl:attribute name="foo" select="bar></xsl:attribute>

Again it is not clear what you want to achieve. The select expression 
../svg:text[@svg:width] select svg:text children of the parent which 
have an svg:width attribute. As attributes in SVG are in no namespace I 
think you rather want
   ../svg:text[@width]
or assuming you want to output an attribute value you want
   ../svg:text[@width]/@width

position() gives the position in the currently processed nodes. As your 
xsl:apply-templates has select="//svg:text[@class='tch']" the currently 
processed nodes are svg:text elements at all levels and position() 
refers to the position in that sequence.
Look into xsl:number to get a different value:

As for extracting the numbers in translate( 40.00, 59.55) you could use 
xsl:analyze-string for that: http://www.w3.org/TR/xslt20/#analyze-string
