Multiple child elements in XSL for each - xslt

Question

Am using for each tag in XSL:
Scenario
Input xml
<root>
<parent>
<Child 1>
<Child2>
data1
data2
data3
....
...
</child2>
<Child2>
data1
data2
data3
....
...
</child2>
<Child2>
data1
data2
data3
....
...
</child2>
</child1>
</parent>
When I am using for each on parent tag, in transformation file it is taking only the first occurence of child 2 repeatedly .
My requirement is, it need to take all the child two elements of child one.

Pretty sure from the comments that you've not got well-formed input XML. You can't have 2 R3 (root) elements at the top level of the document. This could be a push in the right direction.
Which data are you actually hoping to return, and in what format?
You've also hamstrung yourself by not having a repeating group inside Adress.
If you have the option, I'd reform your XML document into something more useful, because currently it's close to unworkable.
Recommend:
<?xml version="1.0" encoding="UTF-8"?>
<AddressBook owner="" date="">
<Address>
<addr firstName="" secondName="">
</addr>
<addr firstName="" secondName="">
</addr>
<addr firstName="" secondName="">
</addr>
</Address>
<Address>
<addr firstName="" secondName="">
</addr>
<addr firstName="" secondName="">
</addr>
<addr firstName="" secondName="">
</addr>
</Address>
</AddressBook>
This way, you can iterate through the elements which are named the same.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="/AddressBook">
<xsl:for-each select="Address">
<xsl:for-each select="addr">
<xsl:value-of select="concat(#firstName, ', ', #secondName)"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Alternately, if you need to add address lines, make a repeating group inside your addr elements, and give them id's to sort by, to make sure they're in order.
Hope this points you in the right direction.
