Trying to count the preceding-siblings?-cousins? of input[@type='radio']
that belong to the current group or form:
Input example:
<html>
<form id="1">
<input type="radio" />
</form>
<form id="2">
<input type="text" />
<radiogroup>
<input type="radio" />
<p>
<input type="radio" />
<input type="radio" />
</p>
<input type="radio" />
<input type="radio" />
</radiogroup>
</form>
</html>
processing form[@id='2'], the result of my xpath should enable the following
indexing of radio buttons:
Output example:
<form id="2">
<input type="text" />
<input type="radio" id="radio_1"/>
<p>
<input type="radio" id="radio_2" />
<input type="radio" id="radio_3" />
</p>
<input type="radio" id="radio_4" />
<input type="radio" id="radio_5" />
</radiogroup>
</form>
the closest i've come is with match="input[@type='radio']"
<xsl:variable name="idx"
select="count(preceding-sibling::input[@type='radio'])+1"/>
which only works per level:
1
<p>
1
2
</p>
2
3
or
<xsl:variable name="idx" select="count(preceding::input[@type='radio'])+1"/>
which ignores the radioGroup boundary.
Basically each radio needs to count the preceding relatives of his own
radiogroup family.
or am i thinking this through wrong...?
TIA!
